Noises the same, don't waste you time.
At first I thought this app was great, then I went to use the heart beat sound, it's the same noise as womb noise. Annoyed.
I have a 5 week old who would cry the minute I put her down at night. After nights of this I was a zombie, once I got this app and played it the minute I put her down...(drumroll) she listen to it and fell asleep within seconds. For this I would have paid much more....infact cd are sold for much more, this is convenient as I just hook up my charger and sit it next to her crib. Even I can sleep thru the sound! First best sleep I've had since she was born!!!
My 1 month old is so soothed by this. When tightly swaddled and provided some movement she becomes very quiet and goes to sleep. Even during her fussiest time . According to Dr Karp the "shushing" has to be pretty loud and that seemed to be the biggest key to her benefiting from this. Only complaint is that I wish it could run in the background while I use other phone applications. Highly recommend for the fourth trimester!
