I was spanked. Though, according to my siblings, not as much as them.
There is absolutely nothing wrong with spanking. All in all, it's a very effective way to punish a misbehaving child. Now, obviously, abuse is wrong, but we are talking about spanking.
I agree with overeasy that you don't necessarily need to cause pain.
Time out? You realize what that is, right? You send them to a corner to think about what they did!
"Are you thinking about that, Billy?"
"Yeah, dad, I'm thinking about it.[/obvious sarcasm]"
Kids probably formulate their new plans in time out!
They need to learn that bad behavior results in something bad. "Time out" is time for kid's overwhelming imagination to work. Spanking is a punishment.
Besides, there are much worse punishments. Like making them pick their own stick. Then you're playing a mental game with them.
