At what age did your child stop believing in Father Christmas

[ishouldprobablygettherapy]

In light of another thread I read some of yesterday, I saw very mixed opinions about when children do and don't believe in Father Christmas. Or whether some others ever do at all.

So my question is, what age did YOUR children stop believing??

Oldest told me he didn't at 10 but suspect he'd been pretending for a couple of years by then. Youngest is 8 and claims she still does but she's also ND and very logical so probably isn't far off working it out.

Mine are 11&14 and haven’t disclosed yet if they believe or not. But they do expect Santa to deliver and for the elf to return each year. They got upset when we went to a well know. theme park and I mentioned the characters weren’t real and just people dressed up. So who knows? One is autistic but not learning disabled.

I worked out a lot earlier than I let on to my parents, I have no idea with my child really as we never did a massive thing just mentioned it a couple of times a year and is now a teenager so not sure the specific age as such

In year 6 because the teachers had to have a chat with kids after some were hysterical after lots got ps5 that year and other kids couldn’t understand why they didn’t, my plan was to tell him
before secondary anyway, my daughter 9 was told by her brother that day but still believes the elf of the shelf gets up to mischief and brings her Christmas Eve box even though I’ve said it was me she refuses to believe it haha
