Ideally, teach me; don't punish me. Reinforce me, instead. Focus on the behavior you want.
Your car wants seatbelts on, so, it annoys you, by only making that, "ding, ding, ding," stop, once you put your seatbelt on. That's negative reinforcement, because something unpleasant was removed, the moment I did the right thing.
"I'm not pleased with you. Remind me what you should be doing," or something equally painless, when I mess up.
You don't need to terrify a Little, to teach him or her. Real consequences are always natural. If my room is a mess, I can't find anything. If it's manufactured, it ain't a consequence; it's. punishment.
I don't like when I legitimately forget something, and someone with more power than I, gets less severe consequences, for forgetting the same thing. If a BIG forgets to separate the pet bird and the pet dog, his consequence, is having to turn around, and go home, to separate them. Mine shouldn't be a dead pet bird! That's bulls hit!
If I'm respectful, kind, and gentle, I'd like to get cuddles. That's positive reinforcement, because something pleasant was added, the moment I did the right thing. I'd prefer encouragement, rather than praise.
"You used your right side, even though it's harder. Keep trying, and maybe it'll be almost as easy as the left," or, "That was a hard problem to solve, but you did it! You figured it out!"
