Nonfiction is also good, if she has subjects she is interested in. The sky's the limit. Nursery rhymes are excellent. A good Mother Goose collection is a great book to have around the house. My First Mother Goose by Iona Opie is a good choice.
Board books are also good.
They are made of heavy cardboard, so they're durable. There are excellent board books with primary colors and just a few, well-chosen words. Barnyard Banter by Denise Fleming is a good choice. It combines excellent pictures with a story that has animal noises. I also recommend two books by Marc Brown.
