I’m writing this as someone who has mostly lived in the US and Canada. Personally, I find the whole “lying to children about Christmas” thing just a bit weird (no judgment on those who enjoy this aspect of the holiday). But because it’s completely normalized in our culture, this is something many people have to deal with.
Two questions:
What age does this normally happen? I suppose you want the “magic of Christmas” at younger ages, but it gets embarrassing at a certain point.
And how does it normally happen? Let them find out from others through people at school? Tell them explicitly during a “talk”? Let them figure it out on their own?
I was kinda on the opposite end of the spectrum lol. I remained steadfast in engaging with the Santa Claus mythos until a pretty late age despite my parents staight up telling me they were the ones getting me presents, and despite knowing that all evidence pointed to them telling the truth, lol.
