Query: Wow! This is amazing.

My sister bought this book for my daughter when she was 6 months old. My daughter has loved it since then. She's now 2 1/2. I have another daughter and she loves it, too. She's almost 9 months and all she does is laugh when she sees the pictures of the babies. She can't get enough of it. The binding is falling apart from use. That's how much my girls love this book. I agree with the reviewer below -- the diversity is great. What a refreshing change.
