I have to take slight issue with blackcurrents' comment If you put your daughter in something sparkly-and-fragile or a skirt without leggings or whatever, you restrict their movement.
I agree with that, but as a parent you don't always have the choice, as I discovered yesterday when DD (2yo) insisted on wearing a party dress, even though me and DH routinely dress her in leggings and tops. I hasten to add, we've never actually bought her dresses, but plenty have been given to her as presents and/or hand-me-downs. Anyway, for me it was a battle not worth fighting, so I acquiesced and compromised by putting leggings on underneath (although DD would have preferred tights, but she let me have my way with that one). Personally, I'm not bothered if the dress gets dirty or whatever, although I would be concerned if it actually constituted a dangerous restriction to her play (in fact, it kept getting hitched up, so it tended to be out of the way anyway!)
What I'm saying is, with the best will in the world, children will sometimes make their own feelings very clear about what they want to wear and you either have a big fight about it, which isn't usually worth it IMO, or you just grit your teeth and let them get on with it.
I suppose I could just get rid of all the dresses she's been given, but I can't quite bring myself to do that as once in a while, it's rather nice to see her in a dress...
I'm very sad to hear about girls being hassled/discouraged when it comes to playing with boys. I have a few friends with boys of DD's age and they love DD getting together with their DSs to play (as do I). I can't get my head around the attitude that somehow it's wrong
How ridiculous.
