Query: Good Book

My 19 month old daughter has both "Bye-Bye, Diapers" and "Bye-Bye, Crib". She responds well to baby Piggy and the rhythm of the stories. She seems to understand the concept that Piggy used to wear diapers, but now she's like the big kids and uses the potty. This is a good book... one that I don't mind reading over and over and over again.
