I have been looking for an informative book to give Gracie (who is nine) that will help teach her what to expect with her changing body. Today I found The Care & Keeping of You: The Body Book for Girls. It's put out by American Girls, which is a bonus because she loves Amercian Girl dolls and I can trust how its written. Topics include: body care, body changes, hormones, acne, bras, eating healthy, menstrual cycles, etc. It seems to be just what I was looking for and best of all I found it at a thrift store for $1!!
I just thought I'd share in case there were other moms approaching this age with their daughters. So far I'd say this is a great book to read with your daughter! It's written very positively and I like how it doesn't make girls want to rush into growing older. It teaches them to love the body they are given and take everything in stride.
