And if deploying the nuclear option doesn't work, then what?
Spanking didn't scare me one bit as a kid. In fact, during one spanking in particular when I was nine, I remember thinking, "My mother's weak. She's pathetic. She can't actually hurt me. I can do whatever I want, and this is the worst she can do!" (And that one actually gave me welts on my butt, which I pointed out to her with glee - I was a tough kid.)
I didn't spank my kids, or threaten to spank them, because there were always better ways to shape their behaviour. And make them think about what they did and reconsider their actions in the future. We were big on learning to think before you act, and when you do mess up, then make restitution for your misdeeds.
My kids, as adults,
still have a healthy fear of disappointing me - or, even worse! - their dad.
For some reason, that's FAR more terrifying to them than a spanking ever was to me.
