I'm not sure I have a list but then I was the one who tackled the wrestler in girl vs. boy football after being clotheslined across the nose poor guy didn't even have the ball

It sounds like she's the victim of some catty girls within her current social circles - might not be too early to check out the book Queen Bees & Wannabes to help deal with the external attitudes... that crap is starting earlier all the time.

Find a few movies with strong female leads - one age appropriate would be Ever After - Cinderella standing up for herself, Very Cool. There are more & more strong female lead action movies or activist movies, but I am a little short on those w/ a PG rating

Also, find an activity that she can start & impove her strength. I'd probably reccomend coed, so as to avoid creating another catty environ. Karate or horsemanship or swimming or cycling or rock climbing - something that challenges her to grow and builds her up mentally & physically - so that she knows She Can do it, and that there is more than slumber parties and glitter gloss in her future. I don't know enough about 4H or Girl Scouts or Boys & Girls club to know if they'd work - so much of that depends on the group & leadership she'd be involved with.

Not only are women strong, but we're brilliant too! I'd also research mentor opportunities in the academic arena, hopefully the school system already has something in place that would be appropriate. (National Engineers day? Math programs? Art Workshops?) Is there a strong & empowered teacher that she looks up to that could take her under her wing?

I hope she finds & embraces her inner strength soon *hugs* to all the little girls out there!
