I notice my DS has been on a reading kick lately and has taken a renewed interest in books he "outgrew" because he can now read much of the books himself. As your DD is more mature than my DS, maybe some of the books in my toddler media thread (under preschool age) would serve as good "outgrown" books for your DD to do the same thing. All the books are stories I read to DS, not ones that he reads independently. I'm particularly thinking of Slinky Malinki, which is quite poetic and charming. I highly recommend Jon Agee's books, too. Simple and deceptively hilarious, much like Mo Willems.
