Ok - so my DDs uncle (DHs brother). meant to be looking after my 18 month old on sat - have a family wedding to go to (my side not theirs). It’s been arranged for months. Today he got really huffy that he was meant to go to a wedding sat (first time I’ve heard of it) and now can’t go - it’s a friend apparently - and neither he nor his GF will be able to go. He asked why DDs gran can’t do it (she’s elderly and infirm), why can’t we get a babysitter (might be too late and no opp to acclimatise). My DH thinks we just make him honour his babysitting obligation anyway but added to the fact that I’m totally pissed off at his attitude I now feel totally uncomfortable leaving my DD after the outburst. So AIBU to drop out of the wedding?
YABU - go anyway and make him babysit
YANBU - stay with your DD
