Lullaby, a Moon Creative Lab venture that offers personalized sleep training services and an app for parents and their newborns, exhibited at a pop-up event in Tokyo called "Papa Mama Boku Watashi," which took place at the main building of the Isetan Shinjuku store Feb.16-21, 2023. Approximately 10,000 people visited the exhibition to see 47 brands selling a wide range of lifestyle items such as clothing, bags, cosmetics and tableware. Lullaby also collaborated with Sandesica on co-branded sleep sacks for newborns and offered gift cards people can use on the Lullaby app.<h3>What is Lullaby?&nbsp;</h3><img src="https://moon-website-prod-images.s3.us-west-1.amazonaws.com/Group_438_c54c862799.jpg" alt="Group 438.jpg">Lullaby is a personalized sleep training service and&nbsp;app for parents and their newborns. Lullaby has welcomed Dr. Mariko Morita, a mother of three children, a physician, and an infant sleep specialist, as a subject matter expert to develop informative sleep support for parents based on scientific evidence of modern daily life in Japan. The app offers three easy-to-use functions for busy parents:<ol><li>Virtual courses provide carefully selected sleep-related resources recommended by physicians according to the baby's age.&nbsp;</li><li>Online schedules keep records of the baby’s sleep and identify the best time for naps.&nbsp;</li><li>In-depth consultation offers a matching service with CISA -certified pediatric sleep consultants when needed.(CISA =&nbsp;Consultant of Infant Sleep Association)&nbsp;</li></ol><h3>Step One: Know Your Baby’s Rhythm</h3>On the first day of the pop-up event, Dr. Morita hosted a fireside chat with special guest&nbsp;Dr.Tomori, a dermatologist. The theme of the discussion was, "Baby’s sleep &amp; Mom's sleep, and the beauty before and after childbirth."<figure class="image"><img src="https://moon-website-prod-images.s3.us-west-1.amazonaws.com/Lullaby_2_d744c73983.jpg" alt="Lullaby 2先生.jpg"><figcaption>Left: Dr. Mariko Morita, Lullaby app supervising doctor and sleep specialist. Right: Dermatologist&nbsp;Dr. Arata Tomori</figcaption></figure>Most importantly, the doctors shared valuable advice such as learning your baby's rhythm, which is the first step to getting good quality sleep – for mom, dad, and baby.&nbsp;Here’s a snapshot of what they discussed during the fireside chat:&nbsp;Dr. Tomori: "Many moms-to-be experience changes in their skin during pregnancy, some of which is caused by the appearance of additional estrogen, a female hormone that is produced more during pregnancy. Symptoms vary, with some women experiencing smoother skin while others develop acne. These changes are normal, and ultimately, moisturizing is the key.”&nbsp;Dr. Morita: "However, it is medically proven that one of the causes of dryness and troubles of the skin is lack of sleep. Sleeping is very important not only for your baby's growth, but also for your skin and hair."Dr.Tomori "Especially after giving birth, the mother’s hormone balance tends to be unstable, so it is important to have a well-scheduled routine to enable better sleep, both for her and the baby. Iron is also very important because it’s good for skin and hair, and even helps you avoid depression – and it’s good for the baby, too."Dr. Morita: “That’s right, because after 15 months, babies are prone to iron deficiency, and iron is important for a baby's sleep. The good news is that in Japan, baby food with iron supplements is widely available.”&nbsp;&nbsp;<h3>Lullaby Merch Was a Hit!</h3><img src="https://moon-website-prod-images.s3.us-west-1.amazonaws.com/Lullaby_1top_ebd76042dd.jpg" alt="Lullaby 1top.jpg">In addition to the app, Lullaby collaborated with Sandesica, a designer of sleep sacks for newborns. The co-branded sleep sack – sold exclusively at this event – was a huge success, selling out the available inventory. The Sandesica sleep sack is a “wearable blanket” that provides a safe sleeping environment for newborns, the development of which Dr. Morita directed.<img src="https://moon-website-prod-images.s3.us-west-1.amazonaws.com/Lullaby_3goods_1514293e09.jpg" alt="Lullaby 3goods.jpg">Lullaby also sold gift cards that parents who have completed Lullaby sleep training could give to other parents interested in Lullaby’s services – the cards were packaged with a multipurpose handkerchief parents could use with their own newborns as a reminder to check out Lullaby’s sleep consultation services, with the aim of lowering the psychological barrier for seeking advice on their baby's (and their own) sleep.<h3>Newborn-tested, Parent-approved&nbsp;</h3>At the Lullaby booth, the sold-out "Sleep Consultation for Baby, Mom, and Dad" session helped pregnant parents and parents with infants aged 0-2 years so they could talk to Certified Infant Sleep Consultants (CISC) who have specialized knowledge in improving sleep habits and infant sleep.&nbsp;Here’s what a few attendees had to say:&nbsp;"I was happy that I could ask many questions.&nbsp;I could tell they are professionals.” (Mom of a 4-month-old)“I asked about my baby’s sleep and also how I can help her take longer naps.&nbsp;I felt better after talking to someone. It’s much better than struggling by myself.” ( Mom of a 5-month-old)&nbsp;"I'm glad I was able to ask a lot of questions! I'd come back again if I have any problems as we continue with the sleep training." (Dad of a 2-month old)"It was very helpful and motivated me to try! I'd like to talk to the professionals again if I encounter any struggles."

<a href="https://www.lullabysleepbaby.com/">Lullaby</a>, a personalized sleep training service and platform for parents and their newborns, has collaborated with industry leader Pigeon Corporation launching a new service together that provides individual online consultations for breastfeeding, diet, and childcare.&nbsp;<h3>Key Learnings</h3><ul><li>Lullaby enhances their app with new consultation service</li><li>Meet the consultants&nbsp;</li><li>Research reveals mothers’ top 3 concerns&nbsp;</li><li>Hearing from the consultants</li></ul><hr><figure class="image"><img src="https://moon-website-prod-images.s3.us-west-1.amazonaws.com/image3_c4541eac51.png" alt="lullaby_pigeon_image3.png"></figure><h3>Lullaby enhances their app with new consultation service &nbsp;</h3>As Certified Pediatric Sleep Consultants1 and under the supervision of doctors, Lullaby provides the latest research on baby sleep health and information tailored to parents in Japan. In addition to its existing infant sleep training service, Lullaby has recently launched a new range of consultation services for parents, including breastfeeding, weaning, and childcare.Through a partnership with Pigeon Corporation, which focuses on creating a more baby-friendly world through its products and services, Lullaby is able to offer more consultation services than ever before. By having access to industry experts such as midwives, nutritionists, weaning/infant food advisors, childcare professionals, speech therapists, physical therapists, teachers, and many others, new parents are able to get the guidance and resources they need throughout their parenthood journey.&nbsp; &nbsp;<h4>&nbsp;</h4><h3>Meet the consultants&nbsp; &nbsp;</h3>Fujiko: nursery teacher Childcare consultation services for mothers and caregivers by a childcare professional, including advice on how to interact with and talk to children to promote their physical and mental development.Momo Mommy: nutrition Consultation on baby and toddler food, including how to prepare easy and healthy food for your child.&nbsp;Hana: midwife from Kaneko Midwifery Clinic Provides help with breastfeeding and weaning.Kaori: Montessori educator and nursery teacher Offers guidance on childcare for children up to 3 years old.&nbsp; &nbsp;<h4>&nbsp;</h4><h3 style="text-align:justify;">Research reveals mothers’ top 3 concerns &nbsp;</h3><figure class="image"><img src="https://moon-website-prod-images.s3.us-west-1.amazonaws.com/image1_851d1bee06.png" alt="image1.png"></figure>After surveying mothers of children who are 0-11 months old, the team learned that the top three concerns for new mothers are breastfeeding, sleep, and baby food.2 Though these things are all normal for new moms, concerns could be about their baby not taking to breastfeeding, not sleeping through the night, having allergies, or being introduced to new foods at the right time.Additionally, interviews with Lullaby app users3 revealed that the ideas about breastfeeding, sleep, and baby food differ from family to family and are difficult to discuss with others, thus creating a need for more individualized consultations with specialists. &nbsp;<h3>Hearing from the consultants &nbsp;</h3>To choose their consultants, Lullaby worked with Pigeon to conduct a series of monitor tests where users were able to consult with area experts. &nbsp;Consultation topic: dealing with the “terrible twos” Consultant: Fujiko, nursery teacherUser feedback: “I was able to talk with her in a very friendly atmosphere and relaxed my shoulders about how to deal with the early stages. It was helpful that she gave me ideas on how to deal with my child and ideas to ease my way of thinking. It was very easy to talk to her! I was impressed with the idea of making food a fun event. I was also impressed by what she said when I told her that my daughter sometimes doesn't eat and I worry about whether she is getting enough nutrition.”&nbsp;Consultation topic: Montessori education Consultant: Kaori, Montessori teacherUser feedback: “I hated myself for getting angry and frustrated when I was working with children, but I was relieved when [Kaori] said that it is difficult unless I know why the child is behaving the way he or she is. She told me why my child was acting the way he was, what he was interested in by age, and not only that, she told me about my son's actual behavior. Just knowing how I should treat my son in these situations and what he is interested in at this time has made me less frustrated than before, and I have learned to be calm with my son and allow him more time for his behavior. As for playing at home, there are many items that can be found at 100-yen stores, and I can quickly incorporate them into my home, so I feel that I am able to spend more time at home on holidays and rainy days, and I feel more fulfilled.”&nbsp;Consultation topic: how to play with children as they grow Consultant: Kanako, physical therapistUser feedback: “First of all, I am surprised and grateful that the process from application to individual consultation went so quickly and that I was able to discuss my concerns right away. In my case, my concern was about my child turning over. In child-rearing books, it is written only that ‘it is time for the child to be able to turn over,’ etc. I did not understand how the child's body works to turn over, and was puzzled as to why the child did not turn over very often. This time, I learned a lot by learning in detail about the causes of not turning over and the mechanism of turning over. First, she praised me for what my child was doing, and then told me what I was not doing or what I was missing, so I could easily accept her advice. Also, Kanako taught us by using her body, so it was easy to visualize what she was doing.” &nbsp;For more information about Lullaby, visit their <a href="https://www.lullabysleepbaby.com/">website</a>, <a href="https://twitter.com/lullaby_nenne">Twitter</a>, and <a href="https://www.instagram.com/lullabysleepbaby/">Instagram</a>.You can download the Lullaby app via <a href="https://apps.apple.com/jp/app/lullaby-%E4%B9%B3%E5%B9%BC%E5%85%90%E3%81%AE%E5%AF%9D%E3%81%8B%E3%81%97%E3%81%A4%E3%81%91%E3%82%B5%E3%83%9D%E3%83%BC%E3%83%88%E3%82%A2%E3%83%97%E3%83%AA/id1541996755?shortlink=c40c4a7&amp;pid=Official_site&amp;c=Official%20Site_LP&amp;is_retargeting=true&amp;af_dp=https%3A%2F%2Fapps.apple.com%2Fjp%2Fapp%2Flullaby-%25E4%25B9%25B3%25E5%25B9%25BC%25E5%2585%2590%25E3%2581%25AE%25E5%25AF%259D%25E3%2581%258B%25E3%2581%2597%25E3%2581%25A4%25E3%2581%2591%25E3%2582%25B5%25E3%2583%259D%25E3%2583%25BC%25E3%2583%2588%25E3%2582%25A2%25E3%2583%2597%25E3%2583%25AA%2Fid1541996755">iOS</a> and <a href="https://play.google.com/store/apps/details?id=com.lullabysleepbaby.app">Android</a>. &nbsp;Sources 1.

On June 30, 2023, Yukari Tago, founder of <a href="https://www.lullabysleepbaby.com/">Lullaby</a>, a personalized sleep training service and platform for parents and their newborns, and Dr. Mariko Morita, the platform's supervising physician, spoke at an event held by the Work-X Office, an organization dedicated to improving the office environment at Mitsui &amp; Co. More than 40 Mitsui employees from different departments gathered for the event and participated in roundtable discussions.Yukari and Dr. Morita discussed Lullaby’s success and shared personal stories and challenges experienced when balancing childcare, work, and homelife. They answered questions and offered several tips and solutions for common problems that parents face.Key Learnings<ul><li>Sleep training significantly improves sleep for infants and parents</li><li>Tips on balancing childcare, work, and homelife</li></ul><hr><h3><img src="https://moon-website-prod-images.s3.us-west-1.amazonaws.com/image2_615f8a855f.jpg" alt="image2.jpg"> The Effectiveness of Sleep Training</h3>Yukari Tago: What I am most proud of is Lullaby's performance of a 99% improvement rate in children’s overall sleep. Our app has a feature that allows users to rate the service, and of the 2,300+ paid napping consultations we provide, 99% of those who have used the service have rated it as good: meaning they have found it to be very successful! Users have shared their success stories and we are very proud of the results.&nbsp; &nbsp;Dr. Morita: The problems related to proper bedtime routines are big and are the number one concern for parents in Japan. Those who are troubled feel very strongly about it because they cannot get proper sleep with a newborn. On the other hand, what about children's sleep in Japan? Comparing the total sleep time of children aged 0-3 years old in 17 major countries, Japan ranks last. Data from the Organization for Economic Cooperation and Development (OECD) shows that Japan also ranks last among the 38 OECD member countries in terms of sleep for adult males and females. I feel this is a good indicator showcasing Japan's low awareness of sleep. Marital discord, divorce, postpartum distress, and postpartum depression are some of the effects people face due to their lack of sleep and frustration with their children’s sleeping habits. In Japan, there is currently no common methodology on how to improve a child’s consistent nighttime crying.The reason I am confident in the 99% improvement rate is because I have evidence. In a survey that analyzed 52 articles on sleep training, 94% of the articles concluded that sleep training was effective in improving nighttime crying, and the results showed that on average, it improved nighttime crying in more than 80% of children. Although the results are solid evidence that sleep training does in fact improve sleep, it is still not widely used in Japan. Even if you go to medical institutions or midwifery centers, they do not provide guidance or proper sleep training techniques. I think that is a problem.Factors that affect sleep deprivation in adults include the fact that children do not sleep, but also the fact that they will wait for their entire family to return home and eat dinner together instead of utilizing that time for rest. However, the impact of sleep problems on children during infancy, the most difficult time of child-rearing, is still quite significant.It often takes on average 1-2 hours to put a child fully to sleep. Children often wake up every 1-2 hours to feed throughout the night or wake up between 4:00 to 5:00 a.m. Parents often find themselves stressed with these new circumstances and often experience difficulties to increase their own sleep time.Studies have shown that the rate of postpartum depression, estimated to be around 10%, has increased to 25% since the coronavirus pandemic. The lack of sleep has had a significant impact on mental health and it’s no surprise that if people can't sleep, they will be irritable and their mental health will suffer.I want Lullaby to improve nighttime sleep deprivation and help create a society where people are not limited in their choices when it comes to parenting.<h3> Dr. Morita on Weaning, Napping, and Work-Life Balance</h3>Dr. Morita: In the preliminary questionnaire for the Q&amp;A during the event, many participants were concerned about their own sleep, including naps and power naps. We also had many questions about children's sleep and balancing home and work.To answer how I do it myself, first of all, I use Lullaby to put my own children to sleep. This is the punchline – haha!However, I think that putting children to bed and getting a good night's sleep is very important for balancing work and family life. What to do if a child is obsessed with breastfeeding?We received a question from a person who has a 2 1/2-year-old and said that her child is attached to breastfeeding. Regarding this, I think it is possible to stop breastfeeding at night. If you want to sleep at night, there is no problem to breastfeed only during the day with nocturnal weaning.However, at that age, I think the child will resist a lot. Be prepared for that, but I think they will get used to it in a week or two. It would be better to first tell the child that he or she will not drink at night, rather than stop during the day as well. How can someone take an effective nap or power nap?It is very important that naps for adults are only 20 minutes maximum. If you sleep longer than that, you will go into a deep sleep and have difficulty waking up, or you will feel foggy when you wake up. I recommend setting an alarm or having some caffeine before napping. It takes about 30 minutes after you drink it to take effect, which is said to be just right. If it is too bright for you to sleep, try using an eye mask. How do you maintain work-life balance?I recognize that work-life balance may be a matter of priorities. By far, the lowest priority is housework. I think it is important not to do the housework itself. I have three children of my own, so I hardly cook meals anymore. I outsource the preparation of meals.When I was pregnant with my third child, I physically couldn't cook anymore due to the morning sickness I was experiencing, so I asked someone to come every week and prepare a week's worth of meals for me and my family. To be honest, it doesn't last the full seven days, but on the one or two days that remain, I would cook dried fish, vegetables, rice, and so on.We also vacuum only once a week. Sorry if it seems dirty! We hire an outside cleaning service to do the cleaning once a week. This alone is a huge relief.This is a small detail, but serving food from containers is also a hassle in itself, so we put storage containers on the table and make it buffet style. The kids are happy when I tell them they can take whatever they would like. I think it's okay to make it a single-plate meal. It might be another small detail, but I tend to be very sloppy too, like not using chopstick rests.As for work, I really wanted to do both work and provide childcare, so I chose this line of work partly because I wanted to make child-rearing time useful while I was able to work.<h3> Yukari Tago on Balance and Mental Wellness</h3>How do you ensure proper sleep for your children and for yourself in the midst of balancing work and family?Yukari: Let me first give you some basic information about me. My son is 6-years-old now. My parents live in Tokyo, 15 minutes by bicycle from our home. My husband's parents live in Shizuoka [over 100 miles from Tokyo].Typically, I drop my child off at around 8:30 a.m. and pick him up at 6:30 p.m., while my working hours are from 9 a.m. to 6 p.m. I have free time at night two-and-half days a week. My husband and I take turns doing this schedule, and we both make sure to have two-and-a-half days of free time each week at night. During that time, I try to spend my free time doing the work I want to finish, meeting people, getting massages, physical therapy, saunas, etc. to refresh myself and take care of my health. By doing this, I maintain my mental health and consciously try to keep myself in a state where I can be happy. How do you maintain your mental health?Mental control is the biggest thing I have learned since I was transferred from Mitsui &amp; Co. to Moon Creative Lab and started working on Lullaby. I always feel like someone is evaluating my work, but that is why I try to maintain my mental health. Of course, there are times when things don't go well, but I think that if my mental health breaks down, my work efficiency will drop very badly.As for work, most of the people working for Lullaby are outsourced, except for me, so the content and volume of outsourcing are clearly defined, and I feel that makes it easy to work efficiently. How do you make time for yourself?I thought it might not be very helpful to know how to generate time, as there are many external factors, but I feel that Moon's flexible working style (core hours are from 10:00 a.m. to 2 p.m.) makes it very easy to work.The scale of the business is still small and I have authority to make most of the decisions. I make decisions on what to do, which I think is one of the main reasons why I can work quickly. Also, since it is a domestic business, there are no overseas business trips.Also, many mothers have a lot of spare time. In order to make the best use of our spare time as mothers, we are gradually preparing useful tools on our app all while consulting with our members. Almost all of our staff members are mothers, and since we are all sleep consultants, our children are all asleep around 9 p.m., allowing us time to catch up and discuss Lullaby. We all have a shared love for the business, so we think about it all the time, 24 hours a day, and I think that is one aspect that allows us to make a lot of decisions quickly.At home, my son is fast asleep by 9:00 p.m., which is a big advantage. Perhaps the most important thing for me is that he’s in good health because of his sleeping pattern. He has attended various preschools, kindergartens, and afterschool programs, and he has received perfect attendance awards to all of them. It may not all be due to sleep, but I still believe it is related to the fact that lack of sleep often relates to getting sick more often.You might be familiar with the book, The 100-Year Life: Living and Working in an Age of Longevity, and I feel that book is the root of my way of thinking. Life is long, so it is a question of what to prioritize now. I'm not able to save much now, but I've decided that it's one stage in the long run, and I'm outsourcing as much housework as possible, and even if I have to live in a smaller house, my first priority is to generate time for travel distance, work, and family.I can relate to Dr. Morita as I also use a make-and-prepare service and have found it to be very helpful.<hr><img src="https://moon-website-prod-images.s3.us-west-1.amazonaws.com/image1_7b2395e541.jpg" alt="image1.jpg">Yukari Tago, founder of Lullaby, is a mother to her son and experienced child rearing years in the United States. While raising her son, she struggled with his frequent nighttime crying and, after practicing a sleep training program she learned while in the U.S., she experienced a dramatic improvement. Using her experience in startup investment in the EdTech industry, she commercialized her idea to improve nighttime crying. She joined Moon Creative Lab from a career at Mitsui to start Lullaby.&nbsp;<img src="https://moon-website-prod-images.s3.us-west-1.amazonaws.com/image3_a6318fc14a.jpg" alt="image3.jpg">Dr. Mariko Morita is a mother of three and supervising physician for Lullaby.

Lullaby is a personalized sleep training service and platform for parents and their newborns.In this article, hear from founder Yukari Tago on how cultural differences and an unfortunate accident inspired her to create Lullaby.&nbsp;<h3> Key Learnings&nbsp;</h3><ul><li>Different countries, different childbirth experiences&nbsp;</li><li>An accidental wake-up call</li><li>Better sleep becomes more than a dream</li><li>Global effects of sleep deprivation</li></ul><hr><figure class="image"><img src="https://moon-website-prod-images.s3.us-west-1.amazonaws.com/image1_74171e0d92.jpg" alt="image1.jpg"><figcaption>Yukari Tago, founder of Lullaby</figcaption></figure><h3>Different countries, different childbirth experiences&nbsp;</h3>The launch of Lullaby was greatly influenced by my experience giving birth in the United States. While the procedures and preparations were more inconvenient and difficult than in Japan, I was surprised at the high level of child-rearing literacy that mothers had in the U.S.Japan is safe and well insured. With an infant medical care card, you can receive free medical care throughout the country. But the situation is quite different in the United States.One time I was at a friend of mine’s US-based home and I had noticed her thick medical dictionaries covered in sticky notes. She told me that she went through every detail of a recent doctor visit’s recommendation, such as whether there is a generic version of a recommended drug, if there is a cheaper alternative, what tests were recommended, etc. She even had suggested options that differed from her doctor's opinion!&nbsp;There were also differences in the birthing process. I had to choose the hospital where I would give birth and also make an appointment with an obstetrician that was covered under my medical insurance. Immediately after birth, I was assigned a pediatrician, and I needed to make an appointment with that doctor in advance. Making separate appointments for the hospital and the doctor was a big difference in itself, but I was indeed surprised when I asked an acquaintance for a hospital recommendation, he replied, "X hospital won't rip you off.”Since I did not have many local acquaintances I decided on a hospital on my own after gathering information using classified websites and other resources. Other mothers I had met were so skilled in gathering such information, which was quite impressive to me. Also, in California, it was not unusual for mothers to return to work three months after childbirth, and it seemed normal for them to invest time and money in preparing for this.One of the things I learned through my experience giving birth in the U.S. was sleep training, which helps babies develop the habit of falling asleep on their own rather than being put to sleep by co-sleeping or being held, as is typical in Japan. My obstetrician told me about the importance of sleep training and how proper sleep health, for both child and parent, is essential. After all, “you can't raise a healthy child if you are exhausted,” as she said.I still wasn't sure whether or not to actually seek sleep training consulting, but an unforeseen event occurred when my child was six months old which drove my need for it. &nbsp;<h3>An accidental wake-up call</h3>My baby was continuously crying at night, leaving me so exhausted that it was hard for me to function throughout the day.When my baby was six months old, he was still crying throughout the night, and I started noticing how constantly foggy my mind was during the day. One day, while he was sleeping on the couch, I took my eyes off of him for just a moment, but when he woke up he fell right off the couch. Had I not been sleep deprived, I probably would have kept a closer eye on him or noticed the moment he woke up.Fortunately, it was nothing too serious. But I remember panicking and rushing to call a cab to take him to the hospital. I was terrified that I might have caused serious injuries. After that scary accident, I decided to seek consulting for sleep training.<blockquote>"You can't raise a healthy child if you are exhausted.”</blockquote><h3>Better sleep becomes more than a dream</h3>Before that incident, I had only considered sleep training. In California, where I had given birth, mothers often returned to work three months postpartum. It was common practice to work with a sleep consultant – a professional that handles sleep training and nighttime crying – to prepare a baby’s sleep environment, allowing the mother to return to work fully equipped to handle nighttime crying and sleep training on her own.At the time I had been reading The Happiest Baby on the Block, a well-known book about parenting and increasing a baby’s sleep, since my son was three months old. But just reading about it didn’t really help the problem I was facing. I still wasn’t sure what to do.The couch incident showed me that I had not been thinking clearly thanks to my baby’s continued night time crying and my own unwavering sleep deprivation. I decided to seek help right away. After receiving consultation and working on sleep training with my husband, I saw a change in my baby’s sleep pattern after just three days.We would leave the room after putting my baby to sleep and watch him through the monitor to measure the time from the start of crying to the end of crying, and we would let him cry for about five minutes, then have contact with him for two minutes, and leave again for a short while, following a time chart. If I had been alone without my husband’s support, I would have broken down when I heard my baby crying.The first few days were pretty rough but to my surprise he quickly began to adapt. After a few weeks, I was actually able to sleep through the night on my own as if by magic. I was so happy about it that when I shared it on Instagram, I was inundated with questions from my friends in Japan, "What is sleep training!?"I received the same response from other people who used sleep training with their infants using the same method as I did. To this day, I still receive comments from users of the Lullaby app saying that they start to see changes in their infants after about the third day. Of course, there are individual differences, but that is the magic of sleep training! You can see improvement almost immediately.For me, the change was drastic. I had read some papers with scientific evidence at the time, but I felt that perhaps if I had the knowledge, parenting would be much easier.I was finally able to get more sleep and I even had enough time to myself that I could take night classes at UCLA Extension. Looking back, the first three to four months after giving birth are a hurdle for just about anyone looking to sleep train because it is a time when the baby does not yet have the strength to sleep through the night. With such knowledge, I would have felt more relaxed about the position I was in.<h3> Global effects of sleep deprivation</h3>Since my job was to develop new businesses in the EdTech industry, I had the opportunity to hear directly from CEOs and COOs about startups in Japan and overseas at the time. Perhaps that is where I was first attracted to the world of startups.Later, I became pregnant in 2016, gave birth in 2017, took maternity leave, and returned to work in 2018. At that time, I particularly remembered the words of a senior employee at Mitsui &amp; Co. who had started his own business. He said that when it comes to new businesses, it’s important to find a deep pain point. If it is deep, and if it is an issue that you want to solve no matter how much money you have to pay, it should be a viable business.&nbsp; &nbsp;<a href="https://www.mooncreativelab.com/stories/design-research">Why Design Research Is Important in Building a Startup</a>&nbsp;After my son was born, for the first time in my life I was faced with the challenge of sleep deprivation. It was the most physically and mentally exhausting experience of my life so far, a true pain point.While sleep training was a common solution in the U.S., it wasn’t in Japan. I thought, "This is it!" I continued to gather information to commercialize this idea. I later learned that Moon was going to hold its first pitch event, so I decided to apply. It seemed like a good opportunity. I pitched my idea for Lullaby and that was the start of my business to improve children's nighttime crying and improve parent’s own sleep.Later, Dr. Mariko Morita, who participated in the project as a supervising physician, also found that the problems related to bedtime are significant.According to data published by Ehime University in 2018, Japan ranks last when comparing the total length of sleep of three-year-olds in 17 major countries1.But it's not just children’s sleep that is affected. Data published by the OECD in 2016 showed that Japanese adult males had the fourth-shortest total sleep duration of all 38 countries at the time (35 OECD member countries plus China, India, and South Africa), and adult females in Japan had the lowest sleep duration2.Sleep deprivation is a major problem in Japan, and many people associate this to their feelings of anxiety about returning to work after parental leave, to fight because of frustration with their children not sleeping, to get divorced because their marriage deteriorates, or to suffer from postpartum depression. Although the methodology on how to improve this nighttime crying problem has not been established at all in Japan, there is evidence for the effectiveness of sleep training.Out of 52 treatment studies from the American Academy of Sleep Medicine, 94% of the studies report that sleep training has been effective in improving nighttime crying, and more than 80% of children demonstrated significant improvement that was maintained for three-six months3. Even though the results are well documented, in Japan, there are no medical institutions or midwifery centers to provide guidance.Research has shown that the rate of postpartum depression, stated to originally be about 15%, has increased to about 30% due to the impact of the coronavirus pandemic4, which may have a significant impact on mental health. And problems related to infant sleep contribute to the increased percentage as well.I created Lullaby to help solve this very problem. &nbsp;&nbsp;Lullaby is currently expanding its business domain by matching sleep consultants, providing reliable childcare information under the supervision of sleep medicine physicians, and developing other services such as general childcare consultation services.The company has also begun joint development with Pigeon, and as of July 2023, plans to offer a "Nen-ne Kaizen Pack," which combines several services including the use of an application for local governments and the provision of sleep seminars for parents. Demonstration tests of the effectiveness of sleep improvement for families with infants and toddlers will begin sequentially in five municipalities: Kashiwabara City (Osaka Prefecture), Namegata City (Ibaraki Prefecture), Otsuki City (Yamanashi Prefecture), Gyoda City (Saitama Prefecture), and Morioka City (Iwate Prefecture).&nbsp;&nbsp;Check out the <a href="https://www.lullabysleepbaby.com/">Lullaby website</a> and <a href="https://www.instagram.com/lullabysleepbaby/">Instagram</a> for the latest information and updates! &nbsp;&nbsp;*1 <a href="http://childsleep.org/guideline/wp-content/uploads/%E6%9C%AA%E5%B0%B1%E5%AD%A6%E5%85%90%E3%81%AE%E7%9D%A1%E7%9C%A0%E6%8C%87%E9%87%9D.pdf">Health, Labour and Welfare Science Research Grants: Research Group on Sleep and Use of Information and Communication Devices by Preschool Children</a> (ed.).

<h3>Mission</h3>Build parental confidence through sleep.<h3>Challenge</h3>Sleep deprivation is a significant pain point for new parents. However, solutions are hard to come by, especially when conservative Japanese parents look down on the concept of sleep training. This prevents new parents (more often women) from achieving fullness of life due to lack of restful sleep.The challenge for Lullaby is to create a scalable, but customizable experience that works for the dynamic lifestyle of new parents.<h3>Solution</h3>Lullaby aims to create and communicate a new culture of “sleep training” to parents in the Japanese market. Lullaby is looking to show how sleep training is healthy and beneficial for both babies and parents. The opportunity for Lullaby is to be a first-to-market mover on sleep training in Japan.
