On Christmas Eve, we make sausage rolls and then go out for a walk with a paper bag of warm sausage rolls to keep our hands warm. We wander around without a set plan, looking for the spirit of Christmas. Once we've found it, we go back home to find a parcel left by our departing Elf, with Christmas Eve supplies of pyjamas, drinking chocolate, candy canes, relaxing shower gel, writing paper and Christmas stockings. We listen to the 9 lessons and carols and do food prep and have a simple meal of lentil soup. The children (now teenagers) shower and get into their pyjamas. They write a note for Father Christmas and leave out a mince pie, drink and a carrot. Everyone watches Christmassy TV (ideally The Snowman). The kids go upstairs and I set up the stockings and gifts from Father Christmas and go to midnight mass. When I get home, I leave the stockings on everyone's bed and go to sleep.
Christmas day starts with the children coming into bed with us in the morning while we all open our stockings. The stockings will generally contain a swanee whistle or kazoo, and a finger puppet each, so we play silly songs and play together with the fingerpuppets while eating chocolate in bed for a while before we get up.
We go downstairs, where we find that the baby Jesus has appeared in the Nativity scene, that Father Christmas has left presents under the tree and written a thank you note for the snack we left out for him (and notice the plate if crumbs and reindeer-chewed carrot left behind) and we switch on the fairy lights and play Christmas music, then fortify ourselves with tea/coffee/orange juice and have a nice but easy to eat/prepare breakfast, usually bagels with smoked salmon and cream cheese.
Then everyone opens their presents. We generally take it in turns to open a present each while everyone else watches.
The adults get washed and dressed, but the children tend to stay in their matching Christmas pyjamas unless they have been given some we exciting clothes to wear.
We then potter around preparing food, nibbling on stocking chocolate and playing with presents (and reading new books and magazines). At around noon we have canapés and we have a big Christmas meal at around three. We phone our families at some point when we aren't eating. We watch TV if there's anything good on. We eat cheese.
We put things in the fridge and go to bed.
On Boxing Day, we watch TV, eat lots of nice leftovers, play/read, digest, and go for a nice walk.
