We’re on our way to see in-laws, having not spent Christmas with them this year. We don’t get on particularly well, barely see them (their fault, not ours) and generally aren’t very close. Every time we go to stay (they live a couple of hours away so it’s always an overnight stay) they mention DS going to stay with them. DS is 4, doesn’t really have much of a relationship with them, and so isn’t particularly comfortable around them, even with us there, let alone if he was on his own! I usually sort of ‘hmm’ and brush it off somehow, but I can’t keep doing that! So, AIBU to tell them no? And what do I say so I don’t start a family civil war?!
