Dtwins birthday is at Christmas, so I do 1st Dec boxes and then a more traditions thing for Christmas Eve, otherwise they get all their birthday and Christmas stuff for the whole year in 5 days.
1st Dec, we have big velvet sacks, containing Christmas PJ's, so we wear them all through the month. Elder DS gets a festive jigsaw to start and finish by Christmas Eve. There will be some form of decoration kit to make, paper snowflakes, paper chains, that sort of thing. Christmas jumpers, and our advents. All stuff to use/do throughout the whole month.
Christmas Eve, we open one box all together. It contains the pop up Robert Sabuda Night Before Christmas, which has come out every year for the last decade with elder DS and DTwins will actually appreciate this year. Everyone's stocking to hang, a bag of clockwork toys (all DC get a new one in their stocking each year, and they all get put in the Christmas Eve box after) it's great to see DS remember his first ones and quite sweet to see them set them all off excitedly. Lastly there are a load of cards from around the world as I participate in a global Christmas card exchange. These cards all go in the Christmas Eve box as they arrive from mid November, and we open them together the morning of Christmas Eve. It's lovely to see all the post marks and different greetings from around the world.
I'm trying to keep Christmas about traditions/memories and less about buying more stuff.
