If we can find a principle to guide us in the handling of the child between nine and eighteen months, we can see that we need to allow enough opportunity for handling and investigation of objects to further intellectual development and just enough restriction required for family harmony and for the safety of the child.

We find that the child who does not yet have language at his command, the child under two and a half, will be able to cooperate with our education if we go easy on the "blocking" techniques, the outright prohibitions, the "no's" and go heavy on "substitution" techniques, that is, the redirection or certain impulses and the offering of substitute satisfactions.

Language makes it possible for a child to incorporate his parents' verbal prohibitions, to make them part of himself....We don't speak of a conscience yet in the child who is just acquiring language, but we can see very clearly how language plays an indispensable role in the formation of conscience. In fact, the moral achievement of man, the whole complex of factors that go into the organization of conscience is very largely based upon language.

For the child whose impulsiveness is indulged, who retains his primitive-discharge mechanisms, is not only an ill-behaved child but a child whose intellectual development is slowed down. No matter how well he is endowed intellectually, if direct action and immediate gratification are the guiding principles of his behavior, there will be less incentive to develop the higher mental processes, to reason, to employ the imagination creatively. . . .

We must remember when we speak of the "negativism" of the toddler that this is also the child who is intoxicated with the discoveries of the second year, a joyful child who is firmly bound to his parents and his new-found world through ties of love. The so-called negativism is one of the aspects of this development, but under ordinary circumstances it does not become anarchy. It's a kind of declaration of independence, but there is no intention to unseat the government.

The parent who loves his child dearly but asks for nothing in return might qualify as a saint, but he will not qualify as a parent. For a child who can claim love without meeting any of the obligations of love will be a self-centered child and many such children have grown up in our time to become petulant lovers and sullen marriage partners because the promise of unconditional love has not been fulfilled.

The experience of a sense of guilt for wrong-doing is necessary for the development of self-control. The guilt feelings will laterserve as a warning signal which the child can produce himself when an impulse to repeat the naughty act comes over him. When the child can produce his on warning signals, independent of the actual presence of the adult, he is on the way to developing a conscience.
