I usually don't like illustrated books for the baby yet. She just doesn't seem as interested in drawings as in photos of real things, especially if they have faces. This one is just so cute, though, and the rhythm of comparisons makes it easy to adopt a little sing-song as you read aloud. It's all about similar items that are large and small: Elephants are BIG, Mice are little etc. My favorites are Ladies are BIG, Ladybugs are little and The moon is BIG, My nightlight is little. It's a bit different from the usual opposite kind of books. If you've got a little one who likes bright, simple pictures and learning about similarities between objects,BIG Little might be a good choice!
