The Miracle of Creation Series is a sensitive, biblical, and user-friendly tool for parents to use as they introduce their children to God's plan for sexuality and reproduction. These picture books Why Do Plants Grow? and Why Do Birds Build Nests? teach younger kids about nature's amazing reproductive processes and gently prepare them for a later discussion of human sexuality in What Is God's Design for My Body?
This is the 3rd time I've read this, once each with 3 kids, at about age 7. It's well done. Two of the kids were more book-learning oriented and did well with the book. The other child preferred to learn by asking questions, which is also fine. The book started prompting that child's questions. I like the Biblical imagery of a garden. I think I also may re-read part of it to the older two kids - the part about the candy store.
