"The child can either, take away the lesson that doing wrong will result in being punished, or they will take away the lesson they can hit things. I personally think the first lesson (doing wrong, or what mummy doesn't want you to do) will result in a spanked bottom will overlook the second, because a kid knows he's not allowed to hit other kids, so in doing so, he will be punished by a spank from mummy."
so its ok for adults to punish by hitting but its not ok for kids to punish by hitting?
