Ours has evolved over the years as the DC have got older. They're 16 and 12 now.
Christmas Eve I put some things on to bake/steam, particularly puddings and the ham and red cabbage. Usually smells lovely.
The DC clean the bathroom and their bedrooms whilst singing carols/dancing/messing about. Then out to lunch in a pub or a v cold picnic. We meet good friends for a long walk and a hot chocolate/look at the lights. Call in and see friends/drop off gifts, maybe the carol service, then home. There's always a letter and a new book by the fire. Letter is from the head elf telling the DC about the year. Pyjamas on and then we read Christmas books, play the piano/sing, play parlour games. Dinner is either out of the slow cooker or a hot buffet. We still do mince pies and milk for Father Christmas and stockings. I read the same set of books to the DC, finishing with The Night Before Christmas and they then have a sleepover in each other's bedrooms.
I love the next bit. I prep the veg for the next day whilst listening to carols on vinyl and then set everything up ie stockings, snowy footprints, presents from us etc. Around 11pm I go and stand/sit in the garden. I love it. It's usually quiet and crisp. I think about the year just gone and the year ahead. I imagine my family and friends waiting for tomorrow. I think about how many excited children, parents, grandparents and couples are asleep in bed across the village and beyond. And I'm not one for any of that #gratitude schtick, but it feels like the most lovely pause. I sit out there for quite a while before going in, locking up and going to bed.
Christmas Day depends on a few factors but stockings, breakfast, presents, family, food, games, music. We always listen to Junior Choice on the radio and I feel emotional. My family comes for lunch and we squash into my snug to exchange presents. I go quite ott with dinner. Lots of sides, various stuffings, 3 choices of meat, vegetarian options etc. Several puddings too, usually served much later. I also do a late buffet with cold meats, pickles, cheeses, mince pies and cake. Plus naff favourites such as Twiglets and Cheese Footballs. Not much TV. We will watch Ghosts but very little else.
It's just happy and relaxed and about family and food and music mostly. I adore it with every fibre of my being.
