Prob more of a wwyd, but here goes. I'm fairly religious, as is my mother & some of my family/friends. DH & his family don't believe in God at all. However, he is happy for me to get DS christened, so we have booked the date with the priest etc etc, told my mother & MIL, but we haven't mentioned it to anyone else or sent out any invites yet as we needed to find somewhere to take everyone to afterwards for food/drinks. Now I find out it's Mothers Day on that day, & everywhere like the local pubs that we would normally book a room in for a party, won't let us book as they want the Mother's Day lunch people in, fair enough.
I'm more than happy to cut the guest list down to just our parents, DH's bro & sister & their partners, and the godparents so that we can just do something simple at our place (no room for any more people there) but MIL has apparently already gone & told all his aunts/uncles/cousins about it, & they are all making plans to come down for the weekend. Considering none of them are religious, and they just want to come down for a pissup get together, WIBU just to tell MIL she has to call them all & cancel it?
