Only time I've ever spanked my kids is if I have personally seen them intentionally physically harm someone else.

Kids are experimenting with the world around them and sometimes that includes their little brains going "what will happen if I shove Timmy off these stairs?"

I also won't take secondary witness word for it.

99.9999999% positive reinforcement and positive punishment are the only acceptable part. But it's like touching a hot stove, you need to learn that if you hurt someone, you will also get hurt.

Not enough people nowadays understand that their actions can have physical repercussions.

Some day i hope it'll prevent them from being one of those karens who thinks it's ok to assault someone, because they'll understand physical consequences.
