Sorry, couldn't resist a lame pun title :)
For religious reasons, we're not 'doing' Santa. Tree, meal, cake, decorations a few gifts, games, relatives, silly hats yes, in spades! - just not the man in red himself. Does anyone else do this? This is the first year that DD1 will be old enough to get the concept 
(NB: religious reasons are simply the wish to keep the focus on Jesus' birthday)
(NB2: when DDs get old enough to be able to talk about it with other children, we're going to couch it in terms of santa being a fun and traditional part of some people's Christmas gift giving, so hope to avoid them spoiling anyone else's Christmas by avoiding saying he 'doesn't exist' etc)
So, are we being Scrooges or do other people do this too?
