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.

    The in utero sound cuts out after about 5 mins. Works great for those 5 mins the my son wakes up. The app says its still playing but no sound. Is there a way to fix this? Full Review

    Great sounds for baby to fall asleep to. Love the fact you can record your own voice and have it played over and over so baby thinks you are right there. Bought the app to show my appreciation Full Review

    Can't cope without this app. I've used this app with my both my 2 babies now and it always drifts them off to sleep within minutes. Can't recommend this app enough! I can get things done much easier round the house. Love how it still plays the sounds when your on different apps or your phone is locked etc. It's so easy to use and with a great choice of sounds you're guaranteed to find one your baby likes :) I wouldn't use any other app to help my babies sleep!

    In utero glitch? This app is great except for one major flaw: the in utero track is unreliable. Sometimes it's the in utero heart beat sound with occasional bubbles, but most of the time when you press play, it's just bubbles. There seems km be no rhyme or reason as to which one it will be, and since the in utero sound is the only one that my daughter will fall asleep to, this is really frustrating. Please fix!

    Best womb sound in town This app is totally worth the money. We use this app every night. It's nice to be able to continually run the sounds for our babies. I'm not sure if i could even sleep without it now. Full Review

    Works under certain conditions, but definitely speeds up bedtime! Took me a while to understand when this app can make a difference, being a first time parent. Now I know when the baby looks drowsy but restless and then the washing machine sounds do the rest! Thanks! Full Review

    Miracle app. X This has helped my baby boy from newborn and upto today now he is 5 months old. He loved the utero sound for the first 2 months..then the washing machine noise then the musical box noise. They are like an off button. Thank you and worth the 1.99 donation after 5 months of easy nights x Full Review

    Timer function is wrong The hairdryer sound works really well to help my baby get to sleep. Unfortunately he wakes up when the sound stops, which is why I paid for the app. However, the 6 hour timer on the hairdryer stops after 2 hours, as I found out at 4am this morning... Edit: changed 3 stars to 2. Had the hairdryer on never-ending for the past two nights. First night was fine. But last night it stopped suddenly after about an hour. Restarted when I hit the power button, but kid was already awake :( Full Review

    This app is often an important part of our bedtime eoutin I used these sounds every day and every night. My babys favourite is the music box but sometimes the vacuum is needed haha.. i find the shushing works quit well. Somtimes i just go through them all and see which one the baby like tonight... so grateful for this incredible tool. And the recording function is great! When i leave the baby with a sitter i leave a recording of myself singing her fave lullaby . So thank you to the creator of this app, so many mothers are sleeping Full Review

    Glitchy Paid for the update thinking it would remove the popping sound in utero but it hasn't. Disturbs my 5 month old! I use the GO ON function which is great, but the pops are horrible. Fix it & you'll get 5 stars. Full Review

    The most used app on my phone For the first year of my baby's life I've used this app numerous times. At first just used the free version, but upgraded to use the noise longer. Is great for road trips, camping, or out of the house in general. Full Review

    My 3 week old loves the in utero. I am excited to try the recording feature as the dishwasher in our house is a favorite. I am hoping you can record more then one thing. If not that would be a great addition to this app. Along with a dishwasher noise. Full Review
