Obviously I dont have boys, but if we did I would have no problem letting them play with what they wanted to play with.

I have a friend who has a boy and they will not let him play with the girls things when they come over because he is a boy and is only allowed to play with boy things. It drives me nuts. Mind you my girls have a mixture of traditional boy and girls toys. Then I have another friend whose little boy loves to dress up and do anything and everything his big sister does!

Oh I just wanted to add that when DD1 was born I made sure everyone knew that we did not want to stereotype her into only traditional girl things, colours, experiences etc.
