Why are toys still so gendered?

Well, yes, but it's been tried before and nature simply takes over. Put young boys and girls in a room full of toys and the girls will gravitate to the dolls and dolls houses and clothes and the boys will head for the cars and lego etc.
I absolutely agree that they must have opportunities and choice, as there will always be some who buck the trend. Myself for instance, I loved toy cars when I was young. But generally speaking they will stick to the things that they naturally love.
It's different when they get older, of course. But aren't there already such choices and opportunities available these days?

You are right it is odd it still happens as we went through all this in the 1970s. However much we as adults feel that every toy should be for everyone small children do seem to go towards the toys designed or offered by manufacturers for each sex. I wonder if your GD will make the dinosaurs into families and play houses with them!! When my children were small they played with each others toys a lot.
Just out of interest I wonder how many female Physicits there are in this country, quite a few I would imagine.

Same here rafichagran.

I have to confess I don't care, I buy the toys the child wants. No matter what gender they are put in.
