"As I said I know I'm in a small minority. As a loving parent I know tried other means, it didn't work, smacking was the absolute last resort. "
I know my mother used smacking in exactly this way Iwannalaylikethisforever. I can't even remember being smacked by her. I can, however recall being told "if you don't stop that you will get a smack." When I was a small child, before I could understand reasoning, I believe it was a very effective method of discipline. She also told me she invariably warned twice before she would carry it out. This was not something done in anger, or in an out-of-control way. It hasn't stopped me being a normal, empathetic human being, nor do I feel in any way traumatised. As I say, I don't even remember her hitting me.
As I said before, I think that it's a difficult question. I don't think that having a law against it will prevent children from being abused as I don't believe it will solve the fundamental problems that cause bad parenting. Also, the number of people here who say they have smacked occasionally out of desperation suggests that it would be impossible to police effectively, and raises the potential of good parents, who love their children dearly, and very occasionally lost control in a limited way (who here who admitted to having lost that control actually lost it to the point of doing significant damage? All of them smacked, none of them ended up beating their children unmercifully, and all of them stopped because of perfectly normal feelings of guilt)... good parents might end up finding themselves in trouble for a one-off minor incident that in the grand scheme of things has almost certainly done no significant damage.
I don't feel that using controlled physical punishment is necessarily better or worse than any other form of punishment. A friend of mine did use spanking in a controlled manner as a form of punishment for her children, right up into teenage. At the time I knew her, when they had misbehaved (which wasn't all that often) they were given the choice of corporal punishment or grounding, and all three of them would choose the spanking every time. Her children always seemed well adjusted. There were no signs that they were less empathetic than other children, and they were certainly not violent themselves. I think there is a lot of emotion attached to this topic. I understand it isn't pleasant to see children being smacked. But I don't feel that a blanket ban will have the desired effect, and it MAY have unexpected undesirable effects if children who would have been smacked just end up with very little discipline being applied at all.
