@Sivonnah, I thought we were the only ones that did that
I’m trying to think of other ones for the week leading up to & the day of Christmas. I know that we have others, but I’m completely drawing a blank right now 
I make a simmer pot or a diffuser blend, sometimes both with seasonal scents. We use seasonal-themed mugs; we have Christmas outfits or tops that we wear. I have a winter-themed onesie with a hood & a reindeer onesie that I wear. The second has a hood with little antlers & a red nose on it. My daughter has a onesie outfit best described as either a candy cane or an elf. My son has a suit type, but it has words that say, Merry Christmas, You Filthy Animal from Home Alone. My other son wears a Bob Ross Christmas sweater that lights up that day.
My daughter & I wear Christmas earrings. I have 10 holes that I put them in… so sometimes it’s reindeer, light bulbs, wreaths, bells, trees, red & green sparkly bulbs at the end of silver chains, red ball ornaments, snowflakes, stockings… I have quite a few. So I will put 4 pairs in & my daughter will wear a pair. I have Christmas-themed stud earrings, too… it’s a thing 
I know we have others that have to do with certain decorations or candles that we light. When I think of them, I will let you know, though!
I always hide their special gift (which is usually something they wanted but small enough for this) somewhere in the tree
If I give them any gift or game cards, I had found these puzzle boxes that I put the card in & they have to solve the puzzle to get it out. So I can wrap them like a gift & put them in their stockings.
My oldest son, his fiance, & I are the only pagans. So I make a witch’s ball ornament each year that I hang on the tree & when we take it down, I hang it in my room for the rest of the winter. I also make an intention pine cone ornament that hangs on the tree. When I celebrate Imbolc by my fire pit, I put it in there with the past year’s Brigid’s Cross
during that ritual/celebration.
