In my opinion, spanking, when applied as a judicious swat or two to get the child’s attention is an appropriate last option for young children. It is a major emphasis - usually employed when a question of safety is involved.
It should be rare, and never devolve into beatings.
I agree.
Even animals understand the meaning of a swat for bad behavior. A cat, a kitty, a dog, a puppy,.. all know to stop or pause the behavior.
