Here's an article describing research that shows that not only is spanking detrimental to kids (increases child's aggression) but that other conventional forms of discipline not only don't "improve" children's behavior but also increase children's anxiety.
Until I read Dr. William Sears' books, I never realized there was another way to "train my children in the way they will go". Unfortunately it was after my first two were school-age and my 3rd was 3 years old. My 3rd child has benefited greatly though and knows that the only spanks he will ever get from now on are "lip spanks" (our joke for kissies). To any who are still spanking in the name of God ( possibly even though your heart is breaking and you feel sick to your stomach every time like I did), please read the following article. Dr. William Sears, a pediatrician, a father of 8, and a Christian. He explains why spanking doesn't have to be the only "biblical" way of disciplining a child... http://www.askdrsears.com/html/6/T062100.asp
