I was a tomboy as a kid, too and I will never discourage that with her.
I refuse to be one of those "older moms" that is so paranoid about everything (AKA politically correct) that I'm not going to let her be a kid - bumps, bruises, stitches and broken bones included - the last 2 I hope I don't have to encounter.
She's a child and she needs to be allowed to be a child and I intend to allow her to be - within guidelines!!!
