I have read the conversation with interest, and can state that I come from a smacking family where a belt or shoe were used to discipline me and my siblings.
To pick up on some of the earlier threads you may be intereted to learn that I went to public school and have 2 university degrees and my parents were relatively well-read.
I now have 2 children of my own, had them in my early 30s having done the travel, got the home and the high flying career etc etc. My DS5 is about as hyperactive and mischevious as I can handle, and to read the TALK pages at times only serves to save my sanity - I am not alone!(although i must confess that i have still meet the parents and/or kids of chldren who are as badly behaved in private or public as my own DS).
Anyhow, all I know now is that smacking is learned behaviour. Despite my so called education, when my children first came along, I did not know how to 'discipline' them without smacking, (and I had read the parenting books!)and I had to make a concerted effort not to smack. Likewise, my DH came from a family that shouts what to my mind is wicked abuse at each other. Needless to say, I now think that that my DH shouts too much at our children in response to his upbringing.
Thankfuly we have both realised our 'weaknesses' and now make optimal efforts to adjust our behaviour and remind each other when we feel that the other is lapsing into old habits. As a tip, I started by not smacking for a day, followed by a few days followed by a week etc and so now I seldom have to resort to smacking. DS no 2 is now 3 and I have never smacked him, but it is true that he is of a much clamer and gentler disposition.
I hope that this will be of some help to both the smackers and anti-smackeers.
PS I have a very loving relationship with my parents, as I always have had!
