You begin teaching your children about their body parts at a pretty young age. As, as with most other subjects, I'm a firm believer in the power of books to help you educate your child on the wonder that is the human body. But it can be hard to find books that explain anatomy to kids that don't sugarcoat things. Some children's book authors seem to be of the mind that children are too young to fully grasp the concepts of the human body, and tend to keep it vague when referring to body parts for children.
Rest assured that there are books don't keep it vague. No matter how old your child is, there's a book that will help explain the human body to them in a clear, educational, and straightforward way — sometimes, you just have to dig a little to find them. From explaining where your belly button comes from, to why hair grows, to reproduction, there are books that cover it all. Because even when you feel comfortable teaching your children about their bodies, it can help to have a book to back you up.
By introducing educational and entertaining books about the human body, you'll instill in them not only a love for learning, but the knowledge to answer any questions they might have about their bodies. So keep a few of these stocked on your kid's bookshelf, and let them read it any time they please.
