I don't remember any particular slap or smack so cannot say whether that type of consequence has affected me. However, I do remember my father flying at me, pulling my plait hard so that my neck snapped back, smacking my bottom all the way up the stairs, throwing me onto my bed so that I bounced off and ended up in a snotty heap on the floor. I remember my mum begging him to stop, I remember her crying, and I remember her holding me for a very long time until I stopped sobbing. He never touched me again.
What on earth had I done? I had refused to share the Spangles (sweets), that I had bought with my thruppeny bit, with my brother who had already eaten all the sweets he had bought with his pocket money. I was shouted at and told to share by my father, so I threw the packet at my brother and it hit him in the face. I was three - it's not my earliest memory but a very vivid one which I have had nightmares about ever since.
It was said that smacking teaches children to smack which turns them into violent adults.
I can't see this as an argument because I never smacked my children and my children used to fight, smack, slap, pull, push, shove, punch, kick, bite - the whole lot.
Similarly, childminding my 2 and half year old twin grandchildren yesterday - it's a matter of separating them/getting in between them to stop them hurting each other all the time. They fight like wild things. Repeatedly telling them to say sorry, that it hurts the other person, that the behaviour is unwanted/unacceptable is a waste of breath.
Where do they learn it from then?
I was smacked but was brought up to believe that smacking was wrong - I was on the receiving end of a violent assault by my father - it didn't make me a violent adult.
