We (as a family) are supposed to be having Christmas lunch with husband's parents and BiL and his family. They've made quite a celebration of it because it is the first time everyone will have got together for Christmas post-Covid and I was looking forward to it too.
2 days in advance: DD2 has a post-cold inner ear problem (vestibular neuritis) and can be fine for hours and suddenly flags and gets dizzy and sick. She might be fine, but she also might not! She will be a bit gutted if she can't go, but if she goes and feels unwell it would be a bit miserable for her.
DD1 is T1 diabetic and has major OCD, which often manifests itself in anxieties about food - she's got a very limited diet and gets very hung up on her own ever-evolving "food rules". She's getting very agitated about whether there'll be things she can eat, she doesn't want to go, she says she won't be able to eat anything if she goes, etc.
Part of me things it would be better for me to stay home with them both and DH and DS can go to lunch. But it seems a bit miserable! DD2 won't want to miss it and she might well be fine. DD1 very definitely does want to miss it, but I don't really feel that letting her opt out of anything challenging is the answer.
AIBU? Yes - they should both go. No - stay home or at least play it by ear.
