Why is your baby crying? Why doesn't your baby sleep through night? Babies have their own good reasons. But even the wisest parents can't read their babies' mind – and babies don't have the words to tell us what's wrong. Baby Stop Crying & Sleep Sounds is an app to help your baby stop crying or fall asleep faster. Simple one-click design to select and start a white noise or music that will gently lull your crying baby to sleep. 1. Stop Crying The growl of a vacuum cleaner might not seem very soothing, but many babies are calmed by a steady flow of "white noise" that blocks out other noises – much like the constant whoosh of bodily sounds they heard in the womb. 2. Baby Sleep Music or singing at bedtime is a tradition that has been passed down since ancient times, across many cultures. 3. Mom's Voice Record papa/mom's or other voice to lull your baby.
