Disclaimer: I don't have kids of my own, however, both myself and my fiance' have spent loads of time in positions of authority over children (Counselors, etc), as well as in positions that have allowed us to observe various methods of parental interaction/discipline, and the subsequent consequences of those interactions with the children (when the parent is not around).
From both our experiences, it was easy to conclude that the children of parents who did *not* use spanking/corporal punishment were usually easier to deal with and generally more well behaved. If the parent tends to use a beating as an extreme measure of control, that leaves everyone else who will ever interact with that child at a disadvantage, since (obviously) they as teacher, family member, aquaintence, cannot haul off and belt the child if they're doing something really wrong.
We both feel that the only thing spanking does is teach a child that they need to behave *just* well enough to avoid being spanked. It creates a confrontational atmosphere, rather than a solutions-based one. It does not impart on them them a true understanding of the consequences of their behavior, other than that they can be hit for something that is "wrong". How does this prepare them against making wrongful decisions later in life? A Boss won't hit them if they are doing wrong, etc...
There are two couples in our lives (a friend of ours and his wife, and my fiance's brother and his wife), both have two children and neither couple spank their kids. They've used positive reinforcement from their first interactions with them, for even the simplest, most trivial things. So, when it comes to punishment time, there is less of a need to ramp up the threat. As soon as the kids sense a change in the parents demeanor, they know it's serious. They ask the kids a LOT of questions, and help them to come to their own conclusions about behavior.
They never say, "NO!" or "Don't" or "Stop that!"...instead saying things like, "What should you be doing instead?", or "If you throw that again, we'll have you donate it to someone who will take care of it", and when the kid throws it again, they've taken a trip down to the Salvation Army and had the kid walk up to the counter and donate the toy themselves. Tears and all.
My in-laws and their kids stayed with me and my fiance' for 12 days, about a month or so ago, and I have to say that we were "retrained", in a sense, on how to speak positively. It was reeeeeeeeeally difficult to remember to do, but once we got the hang of it you could just sense how much it improved almost every situation. It makes the kids less defensive, and more apt to listen and understand a given situation. Most importantly, when the kids were left only with "Unca' Daze" (Me=Uncle Dave) and Auntie Rae, we adults had the EXACT SAME tools for punishment that their mom and dad have when they're alone with the kids. Which was refreshing. I didn't have to worry that they'd misbehave to the extent that I would need to "spank" them, but couldn't...it never, ever comes to that. There are so many other tools available, and bringing the child into a better understanding of their own behavior and the consequences of that behavior through a more positive approach...seems to stick with them more effectively.
I will be using the methods I've learned from both these couples, should we ever decide to have children of our own.
I think it's unecessary because better alternatives are available.
I'm open to suggestions. Since you obviously know everything there is to be said on the matter, would you care to enlighten us? How d'you handle your kids?
