Read thread with interest and determined not to comment due to the sensitive subject matter but found this one comment so disillusioned and, frankly, unbelievable, that I have to.
QUOTE: "....the children don't conclude that Mummy doesn't love them. It's more along the lines of, 'I know that Mummy adores me, and yet now she's really cross with me. Mummy would never want to hit me, so something must be going wrong here... Mummy's love is constant so maybe it's something that I am doing?'"
Do our children rationalise in this way? Maybe those who believe this have genius children or, more probable, are in self denial mode. Most of the time even adults can't be that detached, non emotive and rational!
On the whole contemporary psychology/ psychotherapy/psychoanalysis etc and numerous studies conclude that any discipline based on fear/humiliation(and please, let's not discuss the 'meaning of words' here),negative behaviour et al, is not as effecitve as discipline based on positive behaviour, praise, mutual respect and all that naturally comes with that as the relationship grows.
Smacking/hitting/abuse - whatever you call it - also which i've seen here described as a 'tickle'(!!!), amongst other things, instils fear and resentment and teaches that if things aren't going the way you want them to, you are bigger, you are the one who should be in control, then you can use physical force as a tool to make your point and get the result you want.
There are better ways to teach right from wrong, good manners, respect for yourself and others etc. Praise is a good easy way to do this. Unwanted behaviour, wherever possible should just be ignored. Children very quickly get the message. All children want is recognition and attention. They'd prefer positive attention but negative will do. This is why ignoring is so effective. Explanation also helps. Imagine your child is like an alien just landed. they don't know what's what here in this strange place.
I'm not judging, I'm not perfect - far from it, but i try to make sure i always behave in the best possible way towards others and myself. Physical force in no way fits into this. It is illegal in our society to use physical force against anyone or anything unless you are in fear of your safety or life. That applies to humans and animals alike - but not to children. The thought of smacking my daughter seems alien to me and I have to say, repulsive. I can't imagine how you then go about your business as if nothing's happened. I hope i will always feel this way and never 'lose it' to the point where i scare her physically or mentally. I'd take the itme out or sit on the naughty step myself to calm down!!
And to finish (sorry it's soooo long but once i started i couldn't stop ) one of the parents out there asked how do i stop? JUST STOP. it's that easy. you'll have a couple of mad weeks during which your child/ren won't know what's going on but hopefully they'll soon forget all about physical punishment and move on with you.
