This book is wonderful! I bought this for my niece for her upcoming 4th birthday. My 2 1/2 year old son currently has this book and every time she comes over to our house she is amazed with this book. It has great pictures and the best part it the pronunciation guide for parents! I hate trying to pronounce the names of dinosaurs and my son always wants to know the names. This book tells how big each was compared to humans and little facts about each dinosaur. Great beginning dinosaur book for kids.
