I'll have Christmas with my ds this year. It will generally run as:
Two weeks before Christmas - decorations, tree, gable lights put up as a joint effort. No rush. Collecting greenery from the woods. Shopping for the last few bits. Go to a carol concert.
One week to Christmas - food prep.. Rather than huge volume I go for hand made. Make my own ham, truffles, mince pies, marzipan fruits, yule log etc.
Christmas eve, have a few neighbours over for drinks & nibbles.
Christmas day - lovely breakfast, presents, family video calls, long walk, lunch of roast duck, all the trimmings, mince pies & ginger ice cream, fizz. Then board games, cold meat and pickles for supper, Christmas film, liqueurs, new pjs, bed.
The best thing is not having to rush. Pace yourself. Enjoy each element.
