I'm Jewish and my partner is Christian, so we celebrate some of both, and mush them together in a "Chanumas" celebration. We have a tradition of putting up a tree right after Thanksgiving, too, but this year we've decided to leave the tree down. The kittens are just too curious and wild! We've been lighting Chanukah candles and giving small gifts to the kids, leading up to the bigger ones at Christmas. We'll join my partner's family in PA for the actual Christmas celebration, and then I'll take my kids to my own family in another part of PA for a New Year's Eve celebration with my parents, brothers, and their families. It's kind of busy and tiring, and a bit too costly, but we love the season--especially sharing it together.
Merry Christmas and Happy Chanukah, everyone!
