I received this book as a baby shower gift. It soon became our favorite book to read at about 7 months! By 11 months, my son could point out colors and animals on the back cover. It was a GREAT teaching tool as by 15 months he knew all his colors, each animal, the sounds they made, where they lived, etc...It was so very easy to explore even farther into his little mind with this book. Now, I always include it in my shower gifts!
