We shop for a live tree together as a family every year. Bring it home and set it up. I do the lights (takes a few days) and then enlist the kids' help to add ornaments. We hang stockings, including one for the dog, put lights on the house and decorate out front, and the rest of the interior of the house (garland, candles, various themed items, rugs, guest towels, etc). We attend as many Advent services as we can and look forward to the Christmas Eve Candlelight service.
We bake. Daughter helps with the decorated sugar cookies. I make 2 batches of fudge usually. Chocolate chip/M&M cookies (using holiday colored candies) are made. And usually sausage/cheese biscuits are made, too. We get together with friends and have dinner, usually exchanging small gifts. The kids do a gift swap at church at some point with the youth, or with friends of their own also.
Christmas Eve, after we get home from the candlelight service, everyone goes to bed, and I stay up and stuff stockings, and put out the last gifts (wrapped in different paper, since they come from "Santa".. even though our kids are WAY old enough to know it's made up). We've done it that way since they were small. Christmas morning, we get up (not too crazy early, maybe 7:00) and open gifts and have coffee and a bite of something to eat. Usually done in time to get quick showers and off to church at 11:00. Then back home to relax and have a ham dinner (or leftovers if we did that for Christmas Eve). Since my husband works shift work in the FAA, we have lots of holidays that he is at work, so sometimes we have "Christmas Dinner" as "Christmas Eve Dinner" instead, and so on. Sometimes it's just me and the kids going to the service. But we always and only open gifts as a family. When the kids were small, they opened their stockings, and if Dad was at work, we waited until he got home to open everything else.
We also try to watch the Christmas specials on TV. The Grinch (classic with Boris Karloff voicing the narrator) is my favorite, but also the Year Without a Santa, with the Heat and Snow Misers. Plus Rudolph, of course. The rest are ok, but those three are the big ones.
Since daughter has become a bit more accomplished, I usually will try to get over to the local Hospice and she will set up in the lobby area and play piano for about an hour. Both holiday music and other stuff... the residents, visitors and staff all seem to appreciate it.
We always "try" to go drive around looking at Christmas lights, but several years the weather hasn't cooperated well (just rainy and not very pleasant for being on the roads), but we do try to squeeze that in. If we manage to get out of town family in to visit, we put on some wassail to enjoy as well.
