Something that always strikes me about these threads (and articles etc which advise smacking/spanking) is the use of the words "defiance" and "disobedience" as almost always being the things that smacking should always be used for.
I can see the advantages as a parent of having obedient, compliant children, but when I think of the adult(s) I want my DC to become, neither obedient nor compliant is anywhere near what I want them to be. Polite, respectful, helpful, and able to make good judgements - yes. So surely if you're parenting in a way which expects obedience and compliance, then it gets to a point where you have to undo all of that teaching, and start again teaching them these skills, since obedience and compliance aren't really valued skills or traits in adults. (Compliance in particular but I'd argue against blind obedience too). And sometimes early conditioning can be really hard to undo.
Something funny - typical parent/child situation here which has been happening for decades.
Child does something stupid, say, dropping a can of paint out of a second floor window. Parent/teacher is livid with child and asks them why they did it.
"I dunno," replies the child, "Michael told me to!"
Teacher/parent replies in an incredulous way "Well if Michael told you to jump off a cliff, would you do it? Of course not! Why on Earth didn't you think??"
However, if the same child is asked to tidy their room, but thought this was a batshit crazy suggestion since it will only get messy again anyway and anyway they LIKE it messy - they would still be expected to obey, comply, whatever, with the parent's request that they do so and would presumably get into trouble if they refused.
Two totally different sets of expectations!
As an aside I wanted to highlight amazingmum's shoe-putting-on example, which is an example of obedience - amazingmum the way you describe this sounds exactly the same as the way I have taught DS that we need to put shoes on - modelling the correct example, removing distractions, reasoning, allowing more time, not having as much time for things if he's taking a long time, even down to offering that he can walk in his socks when it's raining (he's never taken me up on this
) but I don't see this as teaching obedience at all.
Teaching obedience would be, to me, more like what Larry describes. The above is just teaching a child to put on his shoes. And apply to drinking juice without spilling it/using toothpaste correctly/being safe around household objects, whatever.
