This is what I think of as a classic potty training book. There's one for a boy and there's one for a girl. You can even get a DVD of the story if you need it. This is a frank description of how a little boy makes wee wee with his pee pee and even has a hole in his bottom for poo. Step by step, a boy hears how he was born making wee wee in his diaper and now that he has a potty, he can decide to go in the potty when he feels things coming. The girl book explains the girl's side of the story.
