The child should be fed at regular and proper intervals, and should be kept warm. But if it cries, as it will do naturally, it should be left to itself to cry. It should not be picked up, rocked to sleep, given another meal nor petted. If it is left to cry, it will learn very rapidly and at the right period of its life that the sounds which it emits are not magical, and it will begin to adapt itself to the fact that it lives in a real world which has not been built solely and only for its own delight. It is curious to note how regression, this instinct to return to the earlier mode of expression, to return apparently even to the pre-birth state, persists in the unconscious mind. During the war, I knew a youth who was intensely agitated by the air-raids. He felt perfectly safe, however, if he could crawl under the bed or table, where he would curl himself into practically the same position as that of a normal baby before birth. When questioned, he had not, of course, the slightest conscious knowledge of why he felt safe in such curious circumstances. But it does not seem improbable that the association of ideas produced by his position and by the confined space created a feeling akin to that feeling of safety which has been his in his pre-birth omnipotent position where nothing could harm him. A similar feeling of security was experienced by many normal persons in cellars and other confined spaces and was probably of the same origin; for there is no doubt that this safety was felt even though their reason told them that a bomb was as likely to reach their confined space as any other place in the neighbourhood. Again, I know of innumerable cases in which soldiers felt very much safer from bombs which fell at night when they were under cover of a canvas tent. Logically, of course, the thing was absurd; emotionally, it was a fact. And all were equally unconscious of any possible reasons for the feeling of security produced. An example of this same tendency at an earlier age is seen in children who cover their heads with the bedclothes when they are frightened.
