E.g. Being "devastated" that you're expecting one gender over another? Maybe it's because I had a long wait for what looks like my one and only child or because I've seen people who desperately want children unable to have them, but I actually get quite annoyed that people say they have such strong preferences.
However this does seem to be quite common and universally acknowledged as a thing which the mother should be sympathised with and cosseted for.
Am I weird for feeling like it's very self indulgent unless there's a reason like an inherited disease one gender doesn't get?
