How do I explain puberty?

We have written two books for kids in the pre-puberty period. What’s The Big Deal? Why God Cares About Sex (Book 3 in the God’s Design For Sex series) is written for kids eight to eleven and is designed for a parent and child to read together. Facing the Facts: The Truth About Sex And You (Book 4) is written for kids eleven to fourteen. Facing the Facts is designed for your child to read alone, though we urge you think about reading it alongside your child and talking about the issues it raises. Ideally, we think each of these books is designed to be read early in its designated age ranges, particularly Facing the Facts in preparation for puberty around age eleven or twelve. These books contain thorough examples of how to talk to your child about the changes of puberty.
