This app Baby Sleep Instantly can be used to help your child / baby sleep. It can also be used by adults suffering with insomnia / sleep disorders.
Not only can you record 360 seconds of the noise that best helps your baby fall asleep (like a song or your own voice!).
Your kids will never cry at night with beautiful sleep music. Soothing songs will relax you and your kids.
You have the option to play the sounds indefinitely (until you decide to stop it) or you can set a timer. If you set the timer for 5/15/30/60 minutes the app will automatically stop after 5/15/30/60 minutes and so on.
