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.

We have good reason to believe that memories of early childhood do not persist in consciousness because of the absence or fragmentary character of language covering this period. Words serve as fixatives for mental images. . . . Even at the end of the second year of life when word tags exist for a number of objects in the child's life, these words are discrete and do not yet bind together the parts of an experience or organize them in a way that can produce a coherent memory.

A two-year-old can be taught to curb his aggressions completely if the parents employ strong enough methods, but the achievement of such control at an early age may be bought at a price which few parents today would be willing to pay. The slow education for control demands much more parental time and patience at the beginning, but the child who learns control in this way will be the child who acquires healthy self-discipline later.

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.

A method of child-rearing is not--or should not be--a whim, a fashion or a shibboleth. It should derive from an understanding of the developing child, of his physical and mental equipment at any given stage, and, therefore, his readiness at any given stage to adapt, to learn, to regulate his behavior according to parental expectations.

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.
