I think what might work for some might traumatize others. I'm fairly certain it turned my dad into a person that does not ever dare to show any emotions of frustration or resentment. I mean my grandpa hit him with the belt, maybe it's a bit far fetched but if you can do X why not Y or where is the line then exactly?
The only time i get physical with one of my kids is if she is going berserk during dinner beyond reason and i cannot get her to move to a different room by herself. I always tell her i don't want to do it but i will (and do) and it always breaks my heart because she will fight hard so i have to be careful while she screams that i'm hurting her. I always try to make the moment as short as possible.
I would never use something to physically hurt them. I don't want to teach them that if you don't get what you want it's ok to physically overpower someone.
