Query: Not the best in its class

I didn't care for this book and returned it. My child is only 3 months old, and I didn't find much for her here at all. Lots of the text is devoted to nursery rhymes and songs. The rhymes you can get from other sources. A lot of the songs are obscure, and there's no music. Not too useful! In addition, I found that the manner in which the text was arranged didn't make the book user friendly. Games Babies Play is a better choice.
