Nice idea, but doesn't work
We ordered this book for our 6 week old who has acid reflux and has had a hard time sleeping. While a great idea in theory, the CD did nothing for us. She found the music scary and it ended up keeping her awake more than anything. We did get her to relax by baby Mozart and use that as our nighttime tool. Best wishes to those looking for a good night's rest: but you won't find it here!
