my 3 sons

So DD is in a total state of flux and really wanting (maybe even needing) to be a boy. If we let her, she would follow DS2 around so closely that she would be attached to him. Now, I waited a long time for a girl and I'm trying to be a bit understanding...but I don't want my DD trying to pee standing up. I know it's a stage many girls go through - especially with older brothers? - BUT, she's 9.5 years old for heavens sake. I also know that emotionally and socially she is MUCH younger (maybe 5)...but that still seems a bit past this stage. Playing with cars and building castles with legos is not a problem...but we are past that. She literally repeats every word the boys say. She stares and them so amorously. I guess I just don't want to be on Jerry Springer some day!
What a torn feeling - I want her to love them, but I don't want her to want to be them!
