Or maybe I’m just naive. DH and I are expecting a baby boy in September. When we found out he was a boy, we thought a plus was that we wouldn’t have to be constantly combating all the lazy sexism we that is directed at girls from every angle. With boys, the stereotyping is still very much there of course, but we somehow thought of it as more benign and easier to bat away.
But it’s already starting to grate on us, and our baby hasn’t even seen the outside of my uterus yet. Example: my mother asked about his movements and I commented that he’s more active after I’ve eaten, to which she replied ‘he’s a typical boy – loves his food’. (So I suppose a female foetus would naturally demur from exhibiting biological responses to the stimulus of calories being transferred to her through her umbilical cord 
). There have also been comments about how he 'can't wait to get on the football pitch' and so on, though maybe she’d say that about a girl too (though I doubt it). The in-laws are equally guilty of comments like this – boys are like this, girls are like that etc (I keep having to remind myself that they’re talking about foetuses and newborns).
Similarly, a friend of mine who has been having trouble breastfeeding her newborn was told by her health visitor that the reason she’s struggling is because her baby is a boy and therefore ‘lazy’. I’ve heard of cases where reduced foetal movement has been put down to the foetus being a ‘lazy boy’ too.
AIBU to find it irritating? I know the comments on their own are silly and harmless, but there’s a drip-drip effect going on. Already certain expectations of him are shifting into position.
WIBU to just direct my mother and in laws to Delusions of Gender and related material, or would that seem uppity / precious / hectoring? Both DH and I have called out these attitudes before, many times, but it never seems to get through.
Also, please share any examples of similar, it would help to know it’s not just us
