im a bit to young to think about having kids yet but one thing sticks out in my head when i think of punishment when i was younger. My dad was real pissed at me one time and picked up a metal pipe and started hitting me with it. Now it didn't hurt that much but a hatred started to grow for him at that moment. After that even if he just yelled at me or even told me what to do I would go nuts with anger. I never really forgave my dad for that so I realllly dont think hitting your children is the right thing to do. It could really mess them up
