With very few exceptions, parents are not aware of the disastrous influence that their own defects, impulses, weaknesses and lack of self-control have on their children. If you wish to be respected by a child, have respect for yourself and be worthy of respect at every moment. Never be authoritarian, despotic, impatient or ill-tempered. When your child asks you a question, do not give him a stupid or silly answer under the pretext that he cannot understand you. You can always make yourself understood if you take enough trouble; and in spite of the popular saying that it is not always good to tell the truth, I affirm that it is always good to tell the truth, but that the art consists in telling it in such a way as to make it accessible to the mind of the hearer. In early life, until he is twelve or fourteen, the child’s mind is hardly open to abstract notions and general ideas. And yet you can train it to understand these things by using concrete images, symbols or parables.
Up to quite an advanced age and for some who mentally always remain children, a narrative, a story, a tale well told teach much more than any number of theoretical explanations.
Another pitfall to avoid: do not scold your child without good reason and only when it is quite indispensable. A child who is too often scolded gets hardened to rebuke and no longer attaches much importance to words or severity of tone. And above all, take good care never to scold him for a fault which you yourself commit. Children are very keen and clear-sighted observers; they soon find out your weaknesses and note them without pity.
When a child has done something wrong, see that he confesses it to you spontaneously and frankly; and when he has confessed, with kindness and affection make him understand what was wrong in his movement so that he will not repeat it, but never scold him; a fault confessed must always be forgiven. You should not allow any fear to come between you and your child; fear is a pernicious means of education: it invariably gives birth to deceit and lying. Only a discerning affection that is firm yet gentle and an adequate practical knowledge will create the bonds of trust that are indispensable for you to be able to educate your child effectively. And do not forget that you have to control yourself constantly in order to be equal to your task and truly fulfil the duty which you owe your child by the mere fact of having brought him into the world.
