We have several traditions~
We go look at Christmas lights (several times) If it is cold, I will fill a thermos with hot chocolate to drink during the ride.
We always read the Christmas Story from the Bible on Christmas Eve.
We do stockings for each other.
We always watch certain Christmas movies, over and over and over again--A Christmas Story, The Grinch (the first one), It's a Wonderful Life and The Charlie Brown Christmas movie).
We bake goodies together as a family to share with others.
Several times during December we will turn off all the lights except for the tree and put on some Christmas music and just talk and drink something warm. So relaxing and nice to reconnect.
