My theory about Christmas is that if any of it is not fun, then stop doing it.
DH and I have a no-gift agreement with all our siblings and their offspring.
We buy for each other, our children, our parents, and a couple more. We have a Google sheet that we both contribute to listing ideas and things we've actually bought.
No Christmas Eve boxes.
We have lots of Christmas bags that we use instead of wrapping paper, so we just get those out each year, drop the presents in, and label them.
We order a nice piece of beef from the supermarket but other than that don't buy much extra food. We'll have a nice roast dinner on Christmas Day - we'll cook it together.
No idea who will do the food shopping. I used to do most of it but DH is perfectly capable so he may well.
DH shopped for crackers because I forgot (more difficult to buy here in the US).
I like making mincemeat and mince pies and boiled fruit cake so I'll do that at some point.
No cards.
No matching PJs or any of that bollocks.
At some point DH will haul home a tree, the children will decorate it.
DH puts up the lights in the garden. He wasn't bothering with it for a while but our neighbours said how much they enjoy seeing them, so he's much more diligent about it now (we like our neighbours a lot).
We don't do much in the way of Christmas parties. The kids are usually in concerts so we'll go and see them, but that's not happening this year.
DH has booked for us to go and do a painting thing because DD loves it so much.
I've booked for us to go and see some Christmas lights a couple of days after Christmas.
No one is feeling stressed. If they were then we'd think about why, and probably drop a few things.
