Bless her!
I must say though most little kids try on makeup just because they're in a playing mood, I put it down to who they spend most time with, a bit unfair of Nadia's father to give her a slap for doing so.
I remember reading an article which frustrated me, a woman had written in to a woman's magazine and stated that her 7 year old son was trying on her clothes and make up nearly every day and she was worried he would grow up gay, now I don't know about anyone else but come on, he is a little kid that wants to play dress up, and it doesn't mean he wants to be gay. Does that mean when I dressed up as a devil at 6 years old that I wanted to be the devil when I grew up, I don't think so!
Anyway for all those mum's out there, don't start worrying about your son's dressing up until they reach say their teens and they're still doing it, then worry!
