I start it all on the first of December. They wake up to a Christmas breakfast with loads of Christmassy baked goods and fruit and yoghurt. I decorate the table and get crackers. They get their advent calenders and a little Christmas craft set.
I do do elf on the shelf (I know everyone on here hate it) but the children just love it. They named their elves hilariously mundane names! They love seeing what they've done every morning (very low key... Think sticking Googly eyes on bananas etc).
We do some Christmas crafts and Christmas baking throughout december. They stir the Christmas pudding and all make wishes.
We go to the pantomime every year with my mum and sisters (my mum pays as part of the children's Christmas presents). They all get those flashy light wands and Ice cream at the interval. We also go to a reindeer farm and see father Christmas there. They also have loads of fun things to do (bouncy castle, fake snow, animals etc).
We all put the decorations up together, and the tree always looks a bit crazy but they love doing it! They put all the decorations that have made in previous years on it. DH also has his own tree which he just puts disco balls on and has a massive disco ball for the top. He calls it 'disco treever' and the kids love it.
On Christmas eve we all go to christingle and then they come back to Christmas eve boxes (also much maligned on here). These have Christmas books, stickers, new pj's and lots of Christmassy sweets. They also have a dvd and board game between them. We play the game and watch the movie, then they all snuggle up in bed.
I love the build up almost more than Christmas itself. All the things we do are traditions me and DH started and the kids enjoy them and look forward to them every year. We do do lots of little bits but nothing is too expensive and It really seems to build the excitement and magic up!
