I was smacked as a child, usually because I'd pushed my mother to the limit and she lost control. It was never hard and tbh I don't think it did me any harm at all and in hindsight it wasn't abusive. I didn't smack my children, probably because my life has been so much easier and I wasn't as stressed. What did affect me was the dreadful relationship between my parents who stayed together because that is what people did in those days. The rows, crying and just general unhappiness made life as a child, rather more difficult than it should have been.Reading some of these posts I just feel there's a real intolerance and lack of understanding of how difficult it is to always "do the right thing" by children but also of how accepting and tolerant children can be, even when a much loved parent "let's them down". My mother smacked me but I knew she loved me and wanted the best for me and for me, at least, that made it OK.
When I was doing a year of unqualified teaching in a Midlands industrial town, I had a 7 year old throw some scissors at another child, I marched him to the headmaster because I wanted him to know that this behaviour was completely unacceptable. The head used the taws on him. Over 50 years later I can still see this child's face and remember his name. That was cold abusive violence, completely different to the smack I got from a parent who loved me and whom I loved. I never again took a child to the head.
