Bugsy2, I actually understand why this idea is so foreign to you. It would have been for me a few years ago.
Now you lot have been looking at 'xxxx best methods of discipline' v smacking, I am looking at 'yyy worst methods of discipline' v smacking. I am coming from the other end of the scale than you all.
I am just sharing with you what my own experience has taught me. That it is sometimes necessary to compare the so called bad methods for your sanity as a parent and for the sake of the children and put them on a scale. Putting emotional abuse in the same bag, and treating it the same way, than smacking or hitting just didn't work fo me. I had to move from being a 'very bad mum' to be a 'bad mum' and then 'a not such a bad mum afterall' (Or at least that's how I have seen myself these last few years). That's why I have been comparairing the methods so much and arrive to some sort of categorization.
As most other parents, you probably have been 'quite a good mum afterall' at all times. Because you surely are a well balanced, emotionally stable mum, you might think that finding the advantages/disadvantages of smacking or blackmailing totally unhelpfull but it helped me because the ways I was using to discipline my child were not the most suitable. I would hope it can help others, if they have had the courage to stay on this thread after so long
