When I was little (up until I was 12 or so), I would receive one present on Christmas Eve: my Christmas nightgown. It was always red and white or red and green, and usually flannel. We'd have a fire going in the fireplace, and I'd warm my new nightie by the fire before changing into it and going to sleep.
On Christmas morning, we had a large breakfast, then opened our gifts. I always had a stocking full of little things "from Santa". Dessert after Christmas dinner was fruitcake, which my mother always flamed. (Pretty to see, disgusting to taste!)
Until I was about 10 or so, we had a real Christmas tree every year. There's nothing like the smell of fresh pine, and our living room smelled of it all December.
Then my parents decided they were sick of dealing with the needles, so it was artificial trees from then on.
Current family traditions... I'm Jewish now, so I celebrate Hanukkah, but we pretty much just light the menorah, nothing fancy. My husband and I visit my family every year for Christmas, and we still do the big breakfast, gift opening, and Christmas dinner with fruitcake
for dessert.
