My Christmas traditions include
A real tree. I'd buy one expensive bauble a year, and occasional packs of cheaper ones to fill the gaps. The tree was usually bought about ten days before Christmas, and kept in the garage. I put it up and decorate it late on Christmas Eve, and early on Christmas morning would make sure the tree was lit up, so that it was part of the Christmas surprise.
We had several Christmas books that we read every year during December. Your little one might like The Jolly Christmas Postman.
Mistletoe hanging up in the hall, to encourage Christmas hugs & kisses.
Father Christmas brought the stocking. Large woolly socks, the child hangs one up, and you secretly pack the other one so you can do a swift exchange late at night. I used to wrap up each individual item, to increase the excitement. It's the Law that there must be a Lindt chocolate Father Christmas sticking out of the top! 
Letters to Father Christmas are a lot of fun for children to do. You can also get letters from FC to your child, some charities do this, which is lovely, you will start seeing the adverts for them soon.
On Christmas Eve you should leave a mince pie and a glass of sherry out for Father Christmas and a carrot for the reindeer. You can drink the sherry later!
Try to go to a panto or a carol concert or an evening walk to see the Christmas lights.
Happy Christmas to you and your family, you will have so much fun!
