The intrinsic problem is that all their clothes are colour coded pink. And then the toys are colour coded pink. The cooking, washing, ironing, child care toys are pink, and are therefore for girls.
I agree that there's nothing wrong with pink, and that it would be nice if we encouraged boys to wear it. But in the grand scheme of things, girls are growing up to think that they are pink, and that the pink toys are for them. And the pink toys are the 'home-making' toys, a lot of the time. I don't think it sends a good message.
Also, I don't really like brain-washing of any kind, and I think girls AND boys are being brainwashed into unnecessary gender role stereotypes, and colour (ie, pink vs blue/black/grey,etc) is one of the major tools that is bringing it about. IMO.
Are ELC still making the stuck-in-the-fifties old fashioned type nurse outfit they used to do? All nurses, male or female, wear the same sort of thing these days, don't they?
