Young children have a natural desire to know more about themselves. This book will answer some of their questions. It's part of a series of books, "Staying Healthy," that includes such titles as Dental Care, Eating Right, Let's Exercise, and Personal Safety. The colorful pictures are clear and eye-catching without being overpowering. The layout of the book is clean; there's lots of white space and clear large type is used. While this may not be a child's choice to pick up and read or browse through, the audience will be there for the caring adult who initiates the reading. One concern: the text states that there are five stages of sleep and then only lists four of them.
