YKW - I think it's much easier to control yourself when you have totally shut the option out of your tools IYSWIM!
It would just never cross my mind to hit them - and they are 8and 6yos now - so well past the smacking age anyway!
Having said that, I have never had much of a problem getting them to do what I want to - they wouldn't have dared come off the naughty step - although goodness knows what they thought I was going to do to them
I also find counting to three still works an absolute dream - but have no idea what will happen the day I get to three and they haven't done what they are asked.
I was never one for lots of talking about having done something wrong - it was always a complete withdrawal of attention, not some long winded rambling!
And tempertantruming children were just left where they were and the rest of us all went off and did something fun while they composed themselves. Even in shops I would just park the buggy up and walk round the corner until it stopped - keeping a close eye out of course
I'm not going to tell anyone else how to raise their children - but equally I do feel that if people say that children 'need' to be smacked, I have to tell them that that is just not the case!
