Cannot recommend this enough! I have been using this on you tube with my 4 month old on and off since he was born, and a lot more recently but it was using up data, so downloaded this so I can play it anytime even in the car! It's like it hypnotises my baby! He could be in the middle of a screaming fit, I play this and it's like an off switch! Literally saved my sanity! Thank you to the creator!
