When I have the choice, I will choose blue for boys and pink for girls. So I bought a blue moses basket not they they slept in them for the DS's, and a lovely pink frilly one for DD. That was my choice.
When it comes to children making decisions, then that is their choices. DD will often pick out beautiful blue and green colours for her clothes, but loves pink too. She is free to choose.
DS is currently playing with a lot of DD's old toys, and many of them are 'girly'.
I think the problem comes when we specifically take a toy away or say 'that's a boy's toy, or girl's toy' to them. Making it a problem.
Or indeed the opposite. I have known some parents so fierce in their desire not to conform to gender stereotypes, they make their girl wear boy clothes, and play with boys toys. One lady I knew, her daughter used to look at DD's dresses and ask if she could get a dress like that. Mum said no way, she's conforming to what society wants (
). So the poor thing was dressed only in very 'boy' clothes. If only she could see the irony.
Her DD got called a boy all the time (she had short hair too) and it used to rile the mother up no end, that she had to keep correcting everyone.
Or my SIL, who really wanted a girl, and dressed her son up in pink, tutus and painted his nails (when he didn't want them done!).
So, I guess I'm saying, let your kids grow and make decisions. Don't force one way, or indeed, the other.
