Our traditions;
Christmas Eve; children have Church nativity play in the afternoon. They also like to listen to carols afterwards.
Christmas Day; morning is always a bit of a rush - I will try and do something nice for breakfast, then we all have to dash off to church - dh goes to one, we go to another (because of work!).
After church, I get busy making lunch, kids will play, or get under my feet, generally just relax.
After lunch, we usually put the repeat of the Kings 9 lessons and carols on the radio, and finally open some presents. During which ds1 mysteriously disappears, and Father Christmas comes to visit, with a present for everyone, but he has to leave ds1's, as he has missed seeing him! We do 'rounds' of presents, so everyone opens one present, then we play a game, then everyone opens another. Dd always has far more than everyone else!!!!
Then we have some tea, put the kids to bed and crack open a bottle and watch something like the Vicar of Dibley Christmas special.
