so i get a phone call today from my fmil and she goes ahead and tells me that fi grandmother just gave her an updated list with kids but his family has no idea who they are. and that includes fi's 6 year old 1st cousin. we said when we got engaged that we were going to have an adult only wedding, kids are allowed at the ceremony, but his aunt still thinks that her child is invited and with thanksgiving coming up and we will all be together, i have a feeling its all going to come out and world war III is gonna take place. how do we handle this situtation. or how do we go about this issue... i would love any suggestions.
