Is Spanking Our Kids Effective or Abusive?

Let me first define what spanking is:

- A single or a number of slaps in a child's bottom using an open hand as means of punishment for a misbehavior. It may involve the use of any implement like rod or belt instead of a hand.

Were you spanked during your childhood? If you were, are you a better person now? If you are a parent, do you use spanking as a form of punishment to get through to your children?

I am a mother and I would never want to hurt my kids in any way as much as possible but there are occasions that I have to establish authority and implement discipline. My husband and I set some house rules that must be strictly observed. Our children are well aware of those regulations and they know the consequences if ever they misbehave.
