Yes! We have a whole Christmas collection. It comes out when the tree comes out (ie start of December) and is packed away again after New Year.

Some favorites:
The Jolly Christmas Postman
Wombat Divine (by Mem Fox)
Jan Brett's Christmas Treasure (I *adore* this book, it has elves, reindeer, hedgehogs, trolls, and lots of snow!)

We've also got a few old-school "treasuries" of varying quality - some of them are terrible old ones from the 1970s but the kids get a kick out them anyway. I would love to get copies of Father Christmas and The Snowman by Raymond Briggs but as a child I always found them to be a bit sad, so will save for when DD2 is a bit older.

This year's purchase (which hasn't yet had it's grand unveiling) is Stick Man by Julia Donaldson (of Gruffalo fame). It's not really a Christmas book but S.C. makes an appearance so that'll do. LOL.
