I haven't bought this book and I'm still trying to decide if it's worth all the effort. This is a spiral bound book that can hardly keep the pages in place. I borrowed this book from the library, and granted it was in pretty bad shape when I got it, but by the time my 16 mos. old and I were ready to return it, the front cover had fallen/ripped off. I'm a book lover, so to me this was horrifying. But, I could never let my son read/look at it by himself just because it wouldn't stay in one piece. He loved looking at the pictures, but it's certainly a book that needs lots of supervision. Sadly, this book nothing you could hand to a child and let them play with without being concerned for the condition that the book is going to end up in. I can't figure out why the publishers thought a sprial bound book was the way to go. Hmph...I thought Baby Einstein was supposed to be "kid friendly".
