In his book "Dare to Discipline", Dobson advocates the spanking of children up to eight years old when they misbehave, but warns that "corporal punishment should not be a frequent occurrence" and that "discipline must not be harsh and destructive to the child's spirit." He warns against "harsh spanking" because "It is not necessary to beat the child into submission; a little bit of pain goes a long way for a young child. However, the spanking should be of sufficient magnitude to cause the child to cry genuinely."
