My nephew realised last year that santa wasn ' t real , it would have been earlier due to the older siblings , except we had a rule in place Santa gives you presents till you don ' t believe in him , and if you out him to the younger kids , you get the piece of coal for christmas . It worked really well for the 10 years or so that we had younger kids around . As for outsiders , we treated it just like religion , some people believe different things , and thats okay too .
