I was doing research on kids books. As I am writing an informative kids book myself and I came up on this book. I have not read this book nor will I ever read it. It isn't worth my time. As a teacher by trade I would like to know...What in the world is the word "SEX" is doing in a child's book? This world is so messed up that I don't even know what to say about it!
