christmasunicorn wow I LOVE the print on the twin pack long johns PJs. But crikey, the prices of Boden these days!! I used to buy loads from them up until about three years ago when they moved all their price points up about 40-50 percent. Now I just can never justify buying from them even with the discount; they are lovely lovely clothes but they have just gone past the point where I think the price is worth it these days. Such a shame, I feel like I'm not their market any more, despite having shopped with them for about 20 years!
The last few years I have got DD some Christmassy pyjamas in the White Co. sale the January beforehand -- I have some nice red and white ones ready for her for this year. (As well as her Christmas Day dress; also from the January Joules sale!) I don't do Xmas Eve PJs; I get some vaguely festive ones ready for the beginning of Advent, as I think it's nice to build the suspense by having them during December (I do make sure they are clean for Xmas Eve though 
) I thought about getting Christmas bedding, but decided not to as I'd have even more Christmassy items to store for the rest of the year! DD has some Christmassy crockery and mugs, and we get out the box of Christmas books and CDs at the start of December, to be read throughout the month. My SIL and I swap small Advent gifts for the kids at the start of December, to get them in a festive mood (usually some Christmassy cookie mixture, decorations to make, and a new Christmas book or DVD). On Xmas Eve DD has a nice supper, and maybe some hot chocolate and a Christmas craft; but we don't do a box or any presents. It's enough excitement as it is!
