This book was my very awkward introduction to what was going on in my body as a preteen from my mother. I really could have done without it. I don't feel comfortable saying anything else on this topic. Please don't traumatize your daughters this way. Just sit them down and talk about it. That's how my mom and I had the sex talk (while watching The Secret Life of the American Teenager), and that went much better. When it comes to that stuff, talking is always better. Trust me.
