Would you ever threaten to take Christmas (birthday, Easter, whatever)away from your kids if they didn’t behave?

I’m watching 4 kids. The younger kids got rambunctious.
The oldest, at 13, started yelling they weren’t get any presents at Christmas if they weren’t good.
“Santa only brings presents to good kids.”
I snapped at him to stop it!
“Well that’s what my mom says,” he protested.
I said I didn’t care and stop saying that.

To me that’s like telling a kid “I’ll ground you for LIFE if you don’t….whatever.”
It is unenforceable and undermines your authority.
If you DO enforce it….that’s a whole different animal.

Thoughts?
