@VawX It's not about instilling fear. And I know this is not something people are supposed to say these days. But kids tend to keep pushing; if they don't run up against any boundaries, the results are a pain in the ass for everyone, and it doesn't even make them happy. I've seen families where the kids know they can basically just get the parents to let them do whatever or have whatever by raising hell until they give in or at least bargain. Some of them, it's not that they're bad parents, they're just busy and they're too tired to hold out, so they take the quick fix and bargain, just calm down and you can have a treat. Of course it just means it will happen more. But I've never seen one of those kids seem very happy with their life. For small children, parents are the rock they rely on. How can a kid feel secure when their parents are weaker than they are? How can they depend on a pushover?
It's good if they know that there are points past which they cannot go. Corporal punishment is a terrible idea as a go-to approach for everyday. It's also a bad idea to ever do it because you're mad. But in the dynamic of implicit "Do what I say." "Yeah? Or else what?" it can be good for them to realize there
is an "or else what?" even, or especially, if it's pretty much never used. It settles the question of who's where in the group dynamic, and they can relax.
Well, I say all that, but I only ever did it once. Daughter was having a massive tantrum that was not ending; all the calmness, firmness, time outs, whatever, was getting nowhere--she was out of control, both ours and her own; I don't think she
could stop. Three swats on the butt and she totally snapped out of it and was fine--it was amazing, it just totally jumped her off the track she was going down, let her do a reset or something. Never got to that point any other time, but that one time it worked amazingly well. And I do think it probably had a positive residual impact too.
It's not like I believe kids should spend all their time doing what their parents order them. I was never interested in programming my kid's life; even when we went for walks, I'd let her investigate what she wanted and just amble along after her, making sure she didn't step in the street or something. She'd give me interesting rocks and pinecones and things; my pockets would end up full. But you do have to make sure they don't metaphorically step in the street. For that, it's sometimes needful they do what you bloody tell them.
