Recommend
Format: Board book
My daughter and I enjoy reading this. She matches the pictures on the pages with those on the buttons. Lots of words she already knows and a good mix of new words. Durable hardback pages.

Who doesn't like Eric Carle books?
Format: Board book
Always been a fan of Eric Carle books. My 10 month old likes the sounds and pictures. He has other similar books, but we like him to see a variety of illustrations. With the pandemic going on, my he is missing out on a lot. One day we will go to the zoo and see real animals, but for now these books will have to do.
