XII. Train them with a constant fear of over-indulgence.
This is the one point of all on which you have most need to be on your guard. It is natural to be tender and affectionate toward your own flesh and blood, and it is the excess of this very tenderness and affection which you have to fear. Take heed that it does not make you blind to your children’s faults, and deaf to all advice about them. Take heed lest it make you to overlook bad conduct, rather than have the pain of inflicting punishment and correction.
After showing the examples of the parenting failures of Eli and David, Ryle continues.
 Some parents and nurses have a way of saying, “Naughty child,” to a boy or girl on every slight occasion, and often without good cause. It is a very foolish habit. Words of blame should never be used without real reason.
 As to the best way of punishing a child, no general rule can be laid down. The characters of children are so exceedingly different, that what would be a severe punishment to one child would be no punishment at all to another. I only beg to enter my decided protest against the modern notion that no children ought ever to be whipped. Doubtless some parents use bodily correction far too much, and far too violently; but many others, I fear, use it far too little.
