I think my parents would’ve died of embarrassment if they had to spend too much time on that topic. They gave me a wonderful book by American Girl that covered all that. It went through puberty, hygiene, good eating and exercise habits, sleep… It was great, I didn’t have to feel embarrassed with my questions. Although if you’re looking for something that covers sex this doesn’t touch that topic. It’s called The Care and Keeping of You. You can probably get it for like five bucks.
Edit: obviously this isn’t a faith based book, but there was nothing in it contrary to our teachings
