Mental health depends upon the maintenance of a balance within the personality between the basic human urges and egocentric wisheson the one hand and the demands of conscience and society on the other hand.

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.

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.

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 can be fairly argued that the highest priority for mankind is to save itself from extinction. However, it can also be argued th at a society that neglects its children and robs them of their human potential can extinguish itself without an external enemy.
