Query: Helps my baby sleep.

We used this at nap and bed time since by son was born. Now that he is 16 months, if he wakes in the night he "fishboxes" himself! He hits the large blue button and the music soothes him back to sleep. When he was younger we joked that we needed a remote control to start it back up when he would wake up.My only complaint is that it seems to eat the batteries pretty well.
