I'm a mother of two girls (2 preteens). I love the American Girl Libraries. Your school library should have them. Also, if their fighting over boys, how old are they?
JHB, I contacted the Dove site they sent 2 coupons and a self-esteem book for mothers and daughters. They told me I could copy the booklet. Is this what you were speaking of? I'm going to take it to the school and see if they are willing to copy the book and give it to our girls.
