That's very naive. Not all kids are the same and for them pain is the only form of discipline they care about. Not all kids will just sit there in time out just because you tell them to. My kid would scream "no" and throw a coffee mug at your face if you tried to scold him or tell him he "Can't get up for 5 minutes" or whatever. He's done it too many times before.
"Trauma" is just a Western fairytale. People in the West are conditioned to think they have it but it doesn't exist. When someone tells me they have "trauma" I think to myself, "n***a please. You're drowning in a foot of water. Stand the fuck up."
I've worked as a teacher with thousands of kids in developing countries where beatings are a way of life. It's funny because teenagers there have way less anxiety than kids who grew up in the West. They're way less confused about who they are and what they want.
In the West people have been brainwashed into believing that the bad things that have happened to them have a lifelong inhibiting effect. It's bullshit. Just to get people to spend money on pharmaceuticals and "therapy", lol.
