Children should be disciplined each according to his or her nature and what works best for them. Doesn't God discipline each of us according to our nature and personality? Spanking, when done correctly, can be a wise way to discipline if a young child responds well to it. Some kids can be taught with a stern look, or a quiet word. Others need to be deprived of something they love in order to learn to obey. Still others need a physical reminder. Many of those here who speak of spanking don't really understand that it can be done correctly and in such cases is certainly not abusive or detrimental.
I have two children, who are each very different. One needed nothing more than a look in order to obey. The other was very stubborn in spirit and needed more strict discipline. Both are very happy, well adjusted young ladies now.
I was spanked as a child. My mother was always controlled and never spanked in anger. She reserved this for the worst offenses. It definitely never taught me violence as a way to handle situations. Quite the opposite. My sister, brother and I knew better than to physically harm one another, and I've never even considered hitting another person in my life. Even young children realize that spanking is a form of discipline that a parent gives to their child in order to teach them.
