I'm probably a try-hard martyr but we do…
Book advent - 24 Christmas stories in December (books are all from charity shops, my childhood books or freebies and come out every year). Basically replace the bookshelf with Christmas books.
Advent calendar- 24 little toys like Lego, Peppa pig characters etc in a Lidl reusable cloth calendar, then their main Christmas present is the house or set to go with them. Toys are collected throughout the year and mainly secondhand. I save Christmas cracker jokes and pop one in there too.
Elf on the shelf - YES I KNOW. But I love it. Ours is female and only really hides round the house or molests other toys.
December 1 breakfast- normal breakfast foods made to look festive. Eg. Toast cut with cookie cutters.
Christmas Eve box - hot chocolate, new pjs, bubble bath, toothbrush, book and snacks for a movie. DH and I have a joint one too with fancy Christmas booze from m&s and a book each. I also put in a Christmas ornament each to represent our year to hang on the tree. The idea is, we'll build up a lovely collection of meaningful Christmas ornaments this way gradually over time.
Bethlehem dinner - ok, so this is wanky… we eat what we think people would have eaten during Jesus' day for Christmas Eve dinner. So, flat bread, hummus, lamb chops etc. It's basically a cold mezze that's all dh's fave foods. So it's easy to cook, eat and clear up.
Toy clear out for Father Christmas- we sort out all our old toys for FC to take back to North Pole with him for children next year. Hence why sometimes dc get secondhand bits in their stockings.
My dh and dc refuse to make Christmas cards, forage for pinecones, bake Christmas cookies or help me do anything else remotely wanky so this is all we do.
