My aunt has twin 4-year-olds, a boy and a girl. She is a HUGE proponent of gender separation, the girl likes everything pink and mummy-ish, the boy likes blue and tractors and trucks - IMO not because they LIKE these things as much as they were pushed on them since they were infants.
Anyway, I went to buy them a couple of carseats for my car not too long ago. The boy wanted a pink one like his sister, because he thought it was cool. I was totally fine with it and would have bought it had there been 2. As such, there was only 1, so I bought it first and installed it. Came back and explained the situation to the twins & their mother. She promptly went "Don't you dare buy him a pink car seat - he is a BOY he does not need anything pink. Pink is for girls."
Of course he then parroted his mother the rest of the time "pink is for girls, I don't want it now," whereas before, we'd had a lovely chat about how every colour is for everyone and a particular colour isn't just for one gender or the other. I spoke to her privately and asked was it really a huge deal for him to have a pink carseat in MY car - it's not as if she would have ever seen it, they only ride with me maybe once every week or two, and no one else would even know!! Her response was "Because eventually he will know that pink is for girls and he will hate it and want you to buy him a new one." I got tiffed and said that it was only the perpetuation of these gender stereotypes that would lead him to think that later.
Anyway - not wanting to cause a huge family row I bought him the black & tan carseat.
Who was BU?
(BTW: The car seat was not 100% pink - here is a link to it and its "masculine" equivalent: "boy" and "girl"
