I'm not into physical punishment at all. I am bigger and stronger than a kid and so I consider it to be a power trip and I also consider it to be a signal that I am out of control of the situation. I really just don't care for physical harm and I include 'spankings' in this category. I don't feel it is okay to hit each other in the name of 'teaching a lesson'. I think it teaches a kid that hitting is okay or kids get the message that they 'won' because the parent lost control and then parent often times ends up apologizing. It's just weird.
Around our homestead doing chores wasn't physical punishment and I did the chores with them. Doing the chores needed to be done regardless; and when one of my kids thought that being oppositional was a great idea and wouldn't or couldn't back down, the chores got done THEN. It was a great way to release the energy and to focus on something other than the negativity that was going on and escalating into confrontational stuff.
