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 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.

The child begins life as a pleasure-seeking animal; his infantile personality is organized around his own appetites and his own body. In the course of his rearing the goal of exclusive pleasure seeking must be modified drastically, the fundamental urges must be subject to the dictates of conscience and society, urges must be capable of postponement and in some instances of renunciation completely.

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.

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.

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.

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.
