When we started using the library last year, we came across a great book called Jazz Baby by Lisa Wheeler. It quickly became favorite with Gavin. We always used the maximum amount of due date extensions allowed so that we could hang on to the book as long as possible. Chocked full of great illustrations and bright colors, I found myself reading it to a beat.
