Description

From the listing uploaded by “appupdater”.

Lullaby is an app that helps sleep-deprived moms and dads get their babies to sleep and improve night crying. helpful in raising children ① Sleep course: Sleep-related knowledge supervised by a doctor (2) Bedtime schedule according to each baby's age We will provide ────── Characteristics of Lullaby ────── ・It is an application developed and supervised by Japanese pediatricians, nurses, and midwives centered on Mariko Morita, a doctor who graduated from the University of Tokyo School of Medicine and has knowledge of pediatric sleep. ・In order for moms and dads who are busy every day not to struggle to find the information they want, we will deliver the really necessary information according to the age of the month in a "word memo" every day. ・ We will deliver the best bedtime schedule for babies according to their age every day. Lullaby proposes an optimal schedule (adaptive schedule) based on the real-time sleep time of the baby that day. ────── What is Lullaby's sleep training? ────── ・I think there are many mothers and fathers who are resistant to "training" their babies. Especially in Japan, crying babies at night has been considered as something that cannot be helped or endured. ・ Nentore is (1) Mothers and fathers create life rhythms according to the growth of each baby (2) Create an optimal sleep environment ③Learn the techniques to make contact with the baby so that it is most comfortable to sleep These will gradually help your baby (approximately 6 months or later) to sleep through the night on their own. Honestly, it's not easy. You need to be prepared to continue. Depending on the family, it may take several weeks, but for the baby, it is a gift of "quality sleep for a lifetime" from mom and dad. Babies don't want to cry, they really want to sleep soundly. But at first, they just don't know how to sleep, just like they don't know how to walk or talk. ・The greatest feature of Nentore is that it has been proven in numerous studies based on scientific evidence. There may be times when you feel like you're going to break your heart, but I would be happy if you could trust Lullaby and work together with us. ────── Effect of Lullaby ────── ・99% of the users who participated in the user test responded that they "felt some kind of improvement" and "I'm glad I did it". ・Actually, sleeping training is childcare that dads are better at than moms. Mommy smells like boobs, so babies wake up at night and get some milk when they are held by mommy! I get a little excited. If your baby wakes up in the middle of the night and is held, he/she can concentrate on sleeping again. Let's get dads to actively participate and have them do childcare that they are good at. ・A baby who sleeps well at night will be like an adult, cheerful during the day, and easy to interact with. If mom and dad can sleep well, they can spend more time with their baby smiling during the day. ・If your baby can get a rhythm to go to bed at the same time every night, mom and dad will have their own time and it will be easier to make plans. Having time to make plans while raising a child is invaluable. ・The baby's sleep is not over once it is improved. After that, you will need to adjust the schedule little by little as your baby grows. Lullaby will become a long-term partner for moms and dads and watch over their babies' growth. ────── Recommended for such people ────── ・ I'm having trouble sleeping, putting myself to sleep, and crying at night. ・ I want to acquire knowledge about sleeping, putting me to sleep, and crying at night ・ I want to keep a childcare diary ・I want to know the recommended bedtime and sleep time optimized for babies ・I want to use the childcare record app to do sleep training and sleep training ────── Lullaby’s official website/SNS ────── HP: https://www.lullabysleepbaby.com/ Instagram: @lullabysleepbaby Twitter: @lullaby_nenne
