*Your baby requires permanent attention*
Your baby might be sleeping and then he/she awakes in the middle of the night.
This app allows you playing beautiful relaxing music either manually or automatically. That means that it will start playing when your baby requires it, so it will start when your baby cries and it will try to calm them down. You can set up for how long should it play.
Sometimes they just wake up in the middle of the night just because and this will help them(us) to keep sleeping. Try it at night or just during a nap.
