If you imagine hitting here as me forming fist and hit them, then maybe i chose the wrong word. Its more like tapping them, hands open. I usually do it when im in crowd and my kid fools around that might disturb people. I’ll tap them twice to get their attention, usually on their shoulder, but never on their head. Then tell them what is wrong with their behaviour. If they do it again ill tap them again and they will know what it means. I never hit my kids with a fist.
I mostly avoid shouting or speaking loudly, so the best way for me to get their attention is usually by “hitting” them.
No hitting that damages them includes moral damage, but then again its hard to measure.
