We don't really plan to do santa here. DS will be 20 months so will be starting to get the xmas thing a little more. We did feel it was a big dilemma as to whether to or not. We had decided not to until my mum was soooo shocked we had to rethink. We aren't going to leave santa out totally but won't make a big deal out of it and if he asks if santa is real we aren't going to pretend that he is but just explain it like a game (ie its a make believe, magic game just for xmas). After all as many of you have already said - kids work it out but still play along. They aren't silly!
