Long after Bratz and Barbie dolls are gone, your DD and DS will follow suit in your train of thoughts, on what is appropriate, what outfit a bratz or barbie doll has on, is not going to contribute to who they are as a young lady, or young man.
That may be true but I still dislike Bratz dolls. I can't help it - although I am fully aware, like I said before, that my DD doesn't look at them in the same way - I see a toy that is representative of this early sexualisation of children, little girls especially, whereas she just sees a pretty doll to play with. So, while I am reluctant to buy one for her, I am not going to ban them - if she is given one, she will be able to play with it. She prefers other toys atm anyway, so it's a bit of a non-issue really.
