A hand on a diapered bottom is useless as a spanking, but it is effective in causing permanent damage to the spine. There is no surface pain to the child thus whipped. Any pain would be deep inside, similar to a fall or a car wreck. Any spanking, to effectively reinforce instruction, must cause pain…. For the one-year-old child, a small, 10- to 12-inch long, willowy branch (stripped of any knots that might break the skin), about one-eighth inch in diameter is sufficient … a one-foot ruler, or belt or a three-foot cutting off of a shrub is [also] effective."
