It no longer makes sense to speak of "feeding problems" or "sleep problems" or "negative behavior" is if they were distinct categories, but to speak of "problems of development" and to search for the meaning of feeding and sleep disturbances or behavior disorders in the developmental phase which has produced them.

It seems to me that we have to draw the line in sibling rivalry whenever rivalry goes out of bounds into destructive behavior of aphysical or verbal kind. The principle needs to be this: Whatever the reasons for your feelings you will have to find civilized solutions.

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.

It can be demonstrated that the child's contact with the real world is strengthened by his periodic excursions into fantasy. It becomes easier to tolerate the frustrations of the real world and to accede to the demands of reality if one can restore himself at intervals in a world where the deepest wishes can achieve imaginary gratification.

An older child, one who possesses a conscience, will be troubled with self-reproaches and feelings of shame for his naughtiness, even if he is not discovered.

In doing this, they have taken the first steps toward the goal of conscience, but there is a long way ahead before the policeman outside becomes the policeman inside.

Our survival as a human community may depend as much upon our nurture of love in infancy and childhood as upon the protection of our society from external threats.
