content: This book is very simple, yet it is very educational, but more important, FUN for my 11-month-old granddaughter. She loves all books, but especially ones that she can interact with. The pullouts on this book are excellent...very strong, yet easy for a young child to move. The pictures and colors are vibrant!! She absolutely loves this book...it is a must to own. Purchase at least one of these great board books by Chuck Murphy...there are 3 others...Shapes, Colors and Opposites. I gave the same review to the other book she has in this series, "Colors" because it too is a great book.
