If she has a good attention span for being read to, you can start reading chapter books with her. When my daughter was that age, we were reading Charlotte’s Web, The Trumpet of the Swan, Stuart Little, and the Chronicles of Narnia. We’d read a chapter or two a night. My two boys, who are 5 and 6, still prefer books with more pictures and lose interest in the longer chapter books. It all depends on the child’s interests, so these may not work out for you yet.
Other good chapter books to start with would be the Junie B. Jones series, or the Magic Treehouse series. There’s also Magic Schoolbus, and if she has a silly sense of humor she might like Captain Underpants (my boys love those crazy books).
