About this app

This app can be used as a form of donation if you like Baby Sleep. It also unlocks longer playback durations. Thank you very much for your decision to purchase Baby Sleep Unlock. We will use your contribution to further improve the app.

This app is intended for babies and their parents It helps babies to fall asleep instantly. Uses classic monotonous sounds (lullabies) proven to be effective by generations of parents! Your babies will soon get used to it and when getting older even demand it and choose their own lullabies. The app becomes an integral part of the babies and their parent every day sleep routine.

Why is my baby crying?

Your baby is fed, has a clean nappy, no issues with colic, you were playing with your baby but still it is crying? The baby is probably too tired, but at the same time unable to fall asleep by itself. This is a common situation of newborns and a situation when Sleep Baby Instant can help the most.

Sleep Baby Instant helps your baby to fall asleep using classic monotonous low frequency sounds proven to be effective by generations of parents:
Such sounds include:
• Shower
• Washing machine
• Car
• Hairdryer
• Vacuum cleaner
• Shush
• Fan
• Train
• Musicbox
• Heartbeats
• Sea and stream...

From practical experience, we have learned that such sounds are more effective as a lullaby than tones, music or sing.

Even for older babies Baby Sleep Instant helps to increase the overall noise level in the room, so that sudden urban sounds like traffic would not disturb your baby from sleeping.

Baby Sleep instant is easy to use so that even your babies can start the lullaby. They just choose one of the available sounds. Each lullaby has a colour and a big image do that babies can find their favourite lullabies. A timer will automatically stop the lullaby when times run out.

We do highly recommend not putting the phone closer to the baby than necessary and turning on airplane mode as well as muting alerts during the entire use of this app.

Simple yet Brilliant!! Thank you for creating inexpensive much more needed application. When we were blessed with twins, you app. Was lifesaver for us. We had sleepless nights but I did some research n came across your app. It is been almost 5.5 years we are using "Music Box" tune. It works like magic. Kids love it. Whenever they have trouble sleeping they ask us to play the tune.

Worth using Pro Version, Basically there is no difference in pro and free version, but the thing is... It's truly effective for kids... When it comes about kids and their happiness... Paying a very small amount not a big thing.... Thanking the developer from depth of heart 💙

Fantastic app! User friendly and modern design. I rarely buy apps but this is an absolute exception. I love all the sound options. I have a question regarding customising sounds. My baby loves the sound of the car but the indicator light is too loud compared to the other background noises and it wakes him if he is sleeping light at that very moment. It would be nice if it could be customizable e.g. reducing or removing some content of the sound sample. Is it something doable in the near future?
