Spanking your children.

By ALL means I completely and solely believe in lovingly spanking my children as a form of punishment. There is a fine line between beating and a couple hits on the butt. However, I totally disagree with anybody else spanking my children, that includes grandparents, aunts, uncles, I don't care. Am I overreacting? I think my husband and I can take care of it, wether we are gone or there while they are acting up family members still will not be able to spank my kids! (Other form of punishments while im away, by all means)
