Um, well, that's cute.
But I'm still against with moms who treat their sons like a girl and dress them up with girly stuff. I think gender differences must be taught to them since they're kids (well, no need to be thoroughly taught, just simply tell them and show them that a boy should behave like a boy and vice versa). This kinda stuff tends to affect their personalities in the future. Just my opinion though, you may decline it if you don't think so.
