For a bit of context, MIL is the sort of person who's incapable of going to doctors appointment and any appointment really alone, mostly because she doesn't speak english, so needs translating. she also won't settle for a translator and expects people to go out of their way to attend with her.
recently, i've been having works done at home, between that, and having gone through a flu at home, i've had to cancel a few appointments of hers as my priority was my son (1yo) who was unwell, and my renovations. since she couldn't find an alternative and wouldn't want her husband to take her (who speaks fluent english), i cancelled her appointment, as again, i couldn't attend myself.
she's been complaining of tooth pain, to which i recommended her a dentist who speak our language, so she was fine to attend on her own as going forward it wasn't realistic for me to have to attend her every appointment.
i have an upcoming hospital appointment, which she knows of, and have asked family if possible to take care of my son, as i'm having an invasive procedure done and will not be able to care for my son at the hospital. my husband had taken off a few days when my son and i fell quite ill in the last weeks, and shouldn't be taking any more days off work, so i assured him my sister would be fine to babysit our son and he didn't need to take off work for me to attend my appointment.
my mil however, thinks she's entitled to her son having to take off work to take her to the dentist appointment. he's said no multiple times, as he cannot attend, yet i've heard bang on about about five times today.
she really is taking the mick, no? would it be wrong of me to stand up since she obviously isn't listening to my husband? he's so passive sometimes and it seems like she's not respecting his answer. i feel it's not my place. but it's really annoying me with every whine i hear.
