An new format for preschoolers on body parts and the differences between boys and girls and dogs?! Simple straightforward depictions and explanations of the parts and functions of the body that are the same and those that are different. There is a short introduction of girls maturing into women and boys maturing into men and the results of that process. There is also a reference to mommies and babies and nursing or bottle feeding. "When boys grow up--they can become daddies." How babies are made is not described. A serviceable book to provide families an opportunity to discuss bodies and all the names for body parts and their functions.
