I remember as a little girl, I liked boy stuff meaning I was never interested in playing with dolls or makeup. I liked to ride my bike, build tree forts, and play with frogs. I was still a little girl (I was just a tough little girl!) and thank goodness this muck wasn't going around at that time. We must allow kids to be kids and maintain their innocence as long as possible. Don't hurt them with this BS.
Tomboys grow up to be beautiful women who are tons of fun to be with.
