I, too, am of the 'not imposing gender stereotypes' onto DS. I did always say that he will be as gender neutral as possible until he makes his own preferences - which, I'm well aware, will be partly influenced by social norm (which influences what he sees being done around him). Same attitude towards icons, too - I didn't want to buy cartoon character logo stuff till he showed an inclination towards such. So, we have a LOT of Bob the Builder now! He took an interest in real life diggers and construction from our drive through Ireland in Jan (with just about every arterial being ripped up and improved!) and it grew from there. We actually probably 'fed' him trains before that and it just hasn't had the same impact (to explain, I live near Puffing Billy and a train line so we don't have to go out of our way to talk about trains!), so Thomas is not nearly as loved, but the only other thing he'll watch with interest.
As for clothes, he still doesn't care less about it - he'll just as quickly put on his cousins pink spotted tunic top as his cargo pants (mummy has a pair just like them ) and has done just that recently!
He's going to cop enough 'training' for the masculine role when I have less control over what he is exposed to, so while he's mainly with me or at childcare (they're great about that sort of thing, advantage of being a university attached centre!) he'll not be told what's a boy or girl thing.
I cringe and have to stop myself from saying something when I hear someone tell a child "Boys don't do that" or "That's for girls" etc - unless Oscar's there. If that kind of thing gets said in front of Oscar, I make a light comment because I don't want him to ever believe I condone that thinking.
He can do whatever he chooses, as long as he's chosen it (and even if that choice is influenced by social norm) and it hasn't been dictated and imposed by shame and ignorance.
