Thus does home-discipline involve the firmness of parental authority united with the mildness of parental love. Love should hold the reins and use the rod. Then it will purify and elevate natural affection, and develop in the child a sense of proper fear, without either disrespectful familiarity or mechanical servitude. The efficiency of home-discipline depends upon its early introduction, upon the decision with which it is administered, upon its adaptation to the real wants of the child, and upon the manner in which it is applied. It should be commenced in due season, as soon as the child can understand its meaning and object. The child should be made to understand that he lives under authority and restraint. This will prepare him for a profitable correction when necessary. The great fault of many parents is that they begin too late to correct their children, and leave them until then in ignorance of its nature and intent. Hence, the child will not appreciate the parent's motive, and will lack that pliability of spirit which is essential to reformation. "The sceptre," says James, in his Family Monitor, "should be seen by him before the rod; and an early, judicious and steady exhibition of the former, would render the latter almost unnecessary. He must be made to submit, and that while young, and then submission will become a habit; the reins must be felt by him early, and he will thus learn to obey them." Home-discipline should be steady, uniform, consistent and reasonable. Both parents and children should be guided by the dictates of reason and religion. It should not be administered by the caprice of passion, nor received in the spirit of insubordination. It should be prompted by a parent's heart, and inflicted by a parent's hand. Convince the recreant child that you correct him from motives of love, and for his own good. Let reason and love be at the bottom of every chastisement; let them hold the reins and guide the rod; and when the latter is used, let it be from necessity. Lay no injunction upon your child without the ensurance of a compliance. Your discipline should never involve impossibilities or uncertainties; neither should you permit your child to sport with your injunctions. Every command should produce either obedience or correction. You should be firm in the infliction of a threatened chastisement, and faithful in the fulfilment of a promise to reward. Many parents are always scolding, threatening and promising, but never execute and fulfil. As a consequence they run from one extreme of discipline to another.
