You don’t have to do anything you don’t want to do.
But I’m not sure why you would call it a manic time especially if you aren’t running about doing all the stuff you’ve opted out of.
We participate in our Christmas lights switch on which is a massive deal and takes at least 8-10 weeks to organise in the build up with lots of meetings and evening events in the build up to take the kids to. Then the actual event.
We have decorations day where we go get the tree and decorate the house and garden. We watch a Christmas film that night.
We go to see Santa and we go to the school Christmas fair, the school Christmas play, the school Christmas disco. We go to the town Christmas craft market and the church Christmas fair. We have a trip to the pantomime or theatre (locally, cheaply).
We buy a new tree decoration on some fun day out during the year so get a new tree memory. We do advent calendars and reverse advent calendars. We go Christmas shopping in town a few times in December.
Santa comes and we track Santa and we leave out carrot and mince pie, hang stockings, read a night before Christmas.
Santa brings gifts and a stocking and is just another person who brings presents, we also give presents and so do friends and family.
We always host so do a lot of cooking, baking and preparing in the build up and calculating where everyone will sleep - so their primary memory will probably be sleeping on the floor in large groups every Christmas to fit all the relatives in. Last year we had 14 to stay, we have a small house so it does get very squeezed.
We host a New Year’s games party each year so that will be a memory I’m sure.
We don’t do elves, or church services, midnight mass or Christmas jumpers. We make all our Christmas cards and wrapping so we don’t buy new things every Christmas. It means we all wrap gifts together which is nice. We have very few hot chocolates, I’m not a fan! We do walk the local Christmas lights advent trail which is in house windows but we don’t participate in it as one of the decorated houses on the map so we swerve that. We do have Christmas Eve PJs but not in a box and they are just nice PJs not Christmas themed.
