Sorry, skullcandy, I didn't get my point across very well, was rushing - I didn't mean time out or naughty step are harsh, I was referring to the attitude in general that you either have to use certain styles of discipline or let children run wild, which is nonsense.
Saying that, I think both time out and naughty step are pretty useless. They might stop a child doing the undesired behaviour there and then and over time make them learn to not do it, but they don't teach a child why they shouldn't do it (excepy mummy or daddy doesn't like it, which is a crappy answer) and, more importantly, they doesn't teach them alternatives to the undesired behaviour. I feel they set children up to constantly fail, because the child is merely being punished, not helped to find different ways of behaving and thinking.
Bunfags, I dunno what the politically correct thing is right now. I don't choose my parenting based on what is trendy. I guess what is big in some circles right now is sort of what I expressed above; not just punishing and disciplining as an end in themselves but giving them a chance to be good; old discipline models work on the presumption that children are always naughty or on the brink of naughtiness, which is a horrible and untrue way to view kids. I personally loosely practice attachment parenting, and I have virtually no behaviour issues with my DS, but he is a toddler, so cannot say how well this will continue to work as he grows. I do have friends who parent similarly with their older kids and they are also very well-behaved; this approach encourages children to be independent, handle responsibility well and be morally autonomous, even though most people mistakenly think it means letting kids run riot and take the piss. I just know I believe in listening to children and finding a way for everyone to be okay with the outcome of whatever, not just being the Big Boss over my family. You can discipline really well with positivity, IMHO; offering choices, encouraging kids to think about stuff, not just letting situations, etc., happen to them, but involving them fully in daily life. Again, easy with one toddler!
That's a bit waffly, sorry.
