My daughter turned into a princess around the age of 3. She wore princess dresses and a tutu more or less constantly for a good 2/3 years and played with her barbies whilst watching Disney films all the time. Aged about 6/7, the gaggle of barbies looked like they had joined Siouxie and the Banshees, she'd chopped their hair off, coloured it all shades of black and blue and they all had black lips and ripped clothes. She's now 23, and has been in and out of uni and I'd say she's quite princessy again. She loves her make up and her sense of style (edwardian at the mo!!) but boy, if any male took her for a passive, girly girl they'd be in for a shock. Edited to add. I think the greatest role model for a little girl is her mum. If she has a ballsy, intelligent mother (and you all sound like you'd fit that description) then she will no doubt turn out the way you hope she will.
