I bought this book for my 15 month-old son, and he adores it. Of his many children's books this book is one of his favorites by far. The pages are easy for little hands to turn, it is a steardy board book, and the flaps are easy to lift and fun for small children. The illustrations are bright and colorful, so it keeps the attention span of little ones. He especailly loves to open the big flap at the end of the book that reveals Luna, the moon. If your child likes Bear in the Big Blue House and Lift- the-Flaps books, they will love this book.
