Larry, are you saying more than it didn't harm you and you don't think it harms other people? You had a fantastic childhood in spite of the smacking, or because of it, or it made no difference?
Because when I 'fessed up to being a crap parent above, the point I think I was making was that in my case, my children seemed to grow up in spite of me, not because of me.
We try so hard to be good parents, and that is exactly what we should be doing. But the downside is that we are so hard on ourselves when things go wrong. We seem to think that we control everything when our children are young, but in fact they are already their own people, and ime it's hard to say whether what you did or didn't do to them when they were tiny, had X, Y or Z effect.
So the only thing we have to go on is the research that has been done. We are lucky enough to have all that knowledge and collective experience available to us nowadays, and we should use it.
So smacking is bad, say the experts. I believe them. Everything in me revolts at the idea of a big person hitting a little person (or anyone else).
