My 4 year old doesn't believe in Santa. We've done the usual Santa things, written letters, stocking from Santa, mince pie with a bite out etc., but she just doesn't buy it. She just says "but it's you really". I haven't even confirmed that it is me! I just say vague "how would I fit down the chimney?" type things. I don't want to outright lie and say "of course he's real you pain in the arse, if you don't believe it you're getting nothing"...but there is no persuading her in the usual ways. She's always been a factual kid. Doesn't believe in fairies, unicorns, anything else fantastical.
Anyway, this year the problem is that she's at school now. And I can imagine when the Santa chat starts then we'll become a pretty unpopular family... I've told her all about St. Nicholas and doing kind things and giving gifts and how st Nicholas was definitely real and he's where Santa started etc., but all that seems to have done is result in her saying the other day "Santa used to give gifts to people but now he's dead" 
which I also don't want her saying at school!!
I've told her we can't tell people he's dead because that would make them sad, and I've said lots of people go to see Santa ("but it's just someone dressed up isn't it") and believe in him etc so we can't tell them he's not real... but she's 4 and is therefore likely just to say something one day because to her it's just a fact.
How do I save Christmas for Reception Class P??!! (Ideally without forcing my kid to believe something she's decided not to!)
