I think the earlier the better, that way they don't see as much awkwardness about the whole subject. My mom finally decided to have "the talk" with me when I was 14 years old....and by then, I had figured it all out in ways that would have been better if she'd just told me at a much, much younger age. It might seem very weird to talk about that stuff now but better it comes from you than other kids at playgroup, etc.

Kudos for homeschooling, though! I was homeschooled thru middle school, and my husband was homeschooled k-12! (In different states; we didn't meet until mid-college.)

I am a health and pe teacher and I definately think children need to know about this stuff early on.. She is not too young to start.. If you want to PM me, i might have some books for ideas that you can use to help her out!! Good luck
