What are you telling LO? Just that he doesn't exist, or just not bringing it up at all? Will you tell them not to tell other kids he doesn't exist?

I know all kids eventually catch on (I think I was 8?) but I'm curious how those of you who are not doing Santa will approach it. When I was growing up everyone I knew did the Santa thing, I knew that people of other religions obviously didn't do Santa but until HB I had no idea so many people didn't do it. And that's ok! I'm just curious since Santa is kind of everywhere, how you'll handle it around others who do go the Santa route.
