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.

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.

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. But our two-year-olds and our three-year- olds experience guilt feelings only when they feel or anticipate disapproval from the outside. 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.

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.

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.

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.
