The Very Hungry Caterpillar is such a sweet, beautifully illustrated book. The simple story, bright colors, and fun cut-out pages keep little ones completely engaged. It’s perfect for teaching counting, days of the week, and healthy eating in a way that feels playful and memorable. My kids ask for it over and over, and it’s one of those books that adults enjoy reading too. A true classic that every child’s bookshelf should have!

One of the best books for babies.

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.
