Exactly Jake, it proves beyond compare that smacking is not the issue for badly well turned out kids. Its the whole package. Unless a mental disorder is at fault, it is how you treat your children that deems how they are turned out. I count to 5 and the kids have until then to stop doing what they are doing, I employed this with my eldest when he was 3 and my youngest has learned by example. I have never had to do anything after I have got to 5 because they have always stopped.
Don't get me wrong, my youngest who is 2 runs me ragged but there are certain words he never disobeys and its not the No word, which I believe becomes voids to them because they hear it so much. Stop! and Wait! work fine for me.
Toddlers wont remember why they got a smack, they'll just remember getting smacked. My aunt used to smack her youngest and he was a monster. He just hit back and shouted back. She learned the hard way that taking things he liked away from him was the only way forward.
Rev with a toddler you can place them on a mat because they wont stay there but you can put them in a safe place (reflection area) for a couple of minutes. It works. Im such a goody, goody I don't even like the word naughty chair or mat etc, I prefer time out lol
I wouldnt hit a pet or a person, why should we hit our most cherished people.
