I definitely prefer the build up myself.
I'm one of the teachers responsible for music in my school so we start learning songs for the Carol Service as seeon as we go back to school after the October half term.
Our tree goes up the same time the advent calendars come out. My DD(7) is VERY excited not to have a cheap choc calendar, but to have a playmobil one.
We take long drives on the way home from school etc to count the Christmas lights as they appear. (I always remember competing with my sisters as a child to see who could spot the most lights!)
They go to their Christmas fair, then mine the week after and then there are all the parties and the concerts.
We go to the Christingle service in our church.
When school has finished we have a lovely few days of last minute getting ready and we bake and make different things.
We go and do something nice together too, and am thinking of taking them to Arthur Christmas this year, as well as the Winter Wonderland at the Zoo.
They go to see an excellent Father Christmas on Christmas eve at the Grosvenor Garden Centre.
They have new PJs etc for Christmas eve night and put out the reindeer food. Am going to parcel up the bits for that night in a nice box for them after pinching the Christmas eve hamper idea from MNetters on here. (Thanks!)
Christmas day is lovely, but the magic is all in the build up for me.
