That Boy of Mine

My 5-year-old Caveman. He's a sweet little boy, very cuddly and loving. His daddy is a little disturbed that he will happily play with Barbies and dress-up with his sisters, but I think it's just because he's such a social creature. His bossy big sister will not tolerate Superman, the Hulk, dinosaurs, or cowboys for very long, if at all. So he'd rather play her games than play by himself. Unfortunately, he just can't stand being alone. And it's also unfortunate for all of us that he'd rather have negative attention (as in screaming) from his sisters than no attention at all. I wish I had a nickel for everytime I heard someone scream "Stop it, Caveman!" or "Mama, make him get OUT of my room!" (That's usually after a dinosaur has decided to crash Barbie's party and start attacking.)
Yesterday, he informed me "Mama, I'm going to teach Juju to be a brat. It's good that there are two of us, because I can pester Gem, and he can pester Mojo."
I wonder how long he's been thinking about that and planning it out?
