I have to wonder if some of the people that are so against "spanking" or other forms of mild physical punishment actually have kids, and if they do, how they REALLY behave.
I have two children, one daughter who is 6yo (6 and a half if you asked her

), and a son who just turned 4 in September. Now, do I "spank" my children? Technically, yes, I guess I do. But I have never pulled down their drawers and given them a sharp smack on the bare-ass. I think that goes a bit far, and is very demeaning. Well, it's more the act of pulling down a child's pants, that I don't agree with, then the smack part. Is it sexual abuse? I think that is going a bit too far, but it certainly does approach the line. I don't think anyone should ever be demeaned, humiliated, or embarrassed by a parent in any way, let alone as a form of punishment.
Now, when it comes to disciplining our children my wife and I initially both said we didn't want to "spank" the kids, and that we were going to go with time-outs and taking away favored toys. But after awhile we noticed the punishments we were using were no longer effective. So, slowly we introduced new punishments for the most severe and/or reoccurring issues, and only after sitting, taking something away, etc. weren't getting through to them. We eventually came to a light slap on the back of the hand or bottom (through the clothes) as a deterrent, or giving them a drop of hot-sauce when they got really mouthy or wise as an absolute last resort. Both of these punishments we had both received as children, and although we didn't have fond memories of them, that was the point. They worked with us, and here we are...so we used them with our kids and found them to be effective as a "last resort". After the first couple times the threat of it is enough to make them think twice before doing something they know to be wrong.
That's another thing, you can't punish a child if they don't know what they are doing is wrong. Otherwise they won't associate the punishment with the act and will remember it more as the parent being "mean" or unreasonable. I believe that the child needs to be old enough to reason, and understand the difference between right and wrong for any type of "punishment" to be effective. But I've noticed that really before a child is able to do these things, they won't need any form of "punishment" b/c a simple "no", spoken in the proper tone is enough to stop a child.
Basically I feel that every child is different, and has to be handled in a way that is appropriate for the situation. I personally can't imagine a situation where a child would ever need to be hit w/ any type of force, embarrassed, humiliated, put-down, beaten, or anything more serious then that, but that's me. It's not my, or anyone's place to tell other people how to raise their children, and the ONLY time that someone (ESPECIALLY the government) should intervene is when a child is in real, physical or psychological danger.
