One of the best books for babies.
Format: Board book
Great book for a one-year-old! Such a colorful, bright, book about a caterpillar that eats all sorts of things before turning into a butterfly. Terrific book for counting also.

Cute and educational
Format: Board book
Besides being such a cute story, the tactile features in this book hold my one year old's attention span: the different size pages and hole cut-outs. Also good for introducing days of the week, numbers, and fruits.
