My family does a few things:
My dad’s extended family, on Christmas Eve, has a large get-together. This ends up being close to 60 people. My dad is one of 9 (two have passed,) so the remaining 7 and their spouses (and the spouse of one of the deceased, ) and I am one of 21 cousins that sprang from those 9. Of those 21, all but 8 of us are married. Of the ones that are married, there is a total of…19? 20? kids…it’s hard to keep track of them all. At any given time, I’m almost guaranteed to have a pregnant cousin/cousin-in-law.
So that’s over 60, but any given year a few won’t/can’t show. We do a big potluck sort of thing…appetizers, desserts, etc…Then we do a large ornament exchange (generally about 2/3 participate in that.) It’s a variant on Yankee Swap. Everyone gets a number, then when your number is up, you can either pick an unwrapped ornament, or steal someone else’s. But that person has to get a new, unwrapped, one.
When my immediate family gets home from that (well, now that we all have our own homes ,we go back to my parents’,) we unwrap one present, which is an ornament to each of us from our parents, and then the ones my brother, sister, and I got for them. We all have “themes.” My sister has rocking horses, my brother has bears, I have mice, my mom has angels, and my dad has snowmen.
On Christmas Day, after we open presents and clean up, we always have wings. Damned if I know how it started, but we get them Christmas Eve during the day, reheat them in the oven, and chow down before actual dinner.
