The cynical me thinks they have the stuff in pink/blue so to stop you reusing baby items for your 2nd, 3rd etc.
I agree.
I also have very strong feelings about "banning" pink rather than having it as just another colour IYSWIM. i.e. parents who 'forbid' their girls to have pink/things with girls on them. Far better to let 'toys be toys' for both girls and boys: so boys get pink if they want and girls blue if they want but do not 'forbid' pink. Not 'decide' that pink is inherently limiting before I get the lectures: MAs in arts psychology and lots of postgrad and work in child development, I don't need a lecture, I understand the other theories.
I had this "pink is sexist and will make you thick" message foisted upon me as a child in the 80s in a rather crude manner by one parent (who didn't do it subtly and had 'read the books'
) and it really affected my self esteem as a teen: I started to obviously look like a 'girl' (i.e. bad/sexist), like boys (i.e. bad role model, lacking ambition), could cook (was told I was holding feminism back by being good at this, although I was also great at science: better to NOT be good at cooking) and so on. Much inner conflict before I realised you could/should have both.
Blue meant aspirational, clever, trying to make your way in the world and be middle class. Pink meant deadbeat bimbo, living to impress boys.
To me, for a while it meant:
Girl = low status. Boy (or girl in blue) = high status.
It further compounds the issue, highlighting different status for different gender identities and thus suggesting one code of behaviour is for 'leaders' with enlightened middle class parents and one for followers bimbos.
Especially as it's trendy for little Cecily to only have blue... but if little Tarquin wanted a dress? No way. I am always impressed by parents of boys who let them have sparkly and 'girly' items: particularly between about 2-6 they love them because they are bright, textured and silly. And far more taboo breaking.
Toys are toys. Within the bounds of not spoiling, let any child have any age-appropriate toys: girls and boys.
