My 9yr old dd is showing signs of starting her periods - we're talking about it in very small doses, lead by her, but I was wondering if there was any reading material that anyone can recommend that we can read through together. She is a little shy about it and so I don't want to give too much information if she isn't ready for it - but thought a book might a good chance for us to have quiet time together or she can read at her own speed.
