On the other hand, the mother who understands the needs of the child from a speech-forming standpoint will not insist on the child repeating the word time after time as if it was not understood. She will strive hard to understand the first time, even though the expression is imperfect and difficult of interpretation, and her nimble mind having figured out what it is that the child desires, will say, "Baby wants a cooky?" Here the child, in his comparatively new occupation of talking, finds a deal of delight in knowing that his words have been properly comprehended and feels a new confidence in his ability to express thoughts--which confidence, by the way, is essential to normal speech development in the child. It has the further effect of correcting the tendency of faulty utterance, and in time will result in the complete eradication of the natural tendency to "baby-talk" which is too often encouraged and aided by the habit of parents in REPEATING THE BABY-TALK. In no case, should defective utterances be repeated, no matter how "cute" the utterance may seem at the time. Many speak indistinctly throughout their entire life simply because of the habit of their parents in repeating baby-talk, thus confirming incorrect images of numerous words. SPEECH DISORDERS IN THE FORMATIVE PERIOD: The Formative Period may mark the beginning of a speech disorder and in many instances chronic cases of stuttering and stammering may be traced to a simple disorder which first manifested itself in the ages between 2 and 6. Speech disorders arising in this period may be traced to any one of a number of causes. In a child of five, for instance, the diagnostician would look for evidences of an inherited tendency to stammer or stutter; he would look also for circumstances which would show that the child had acquired defective utterance through mimicry of others similarly afflicted or through the unconscious imitation of the defective speech of those immediately about him. Failing to find any hereditary tendency to a speech defect or any evidence that the disorder had been acquired by imitation or mimicry, the next step would be to determine whether or not the trouble had been caused by disease or injury. As explained in Chapter III, the diseases of childhood, such as Whooping Cough, Scarlet Fever, Diphtheria, Acute Chorea, Infantile Cerebral Palsy and Infantile Paralysis are frequently the cause of stuttering or stammering, and a history showing a record of these diseases would result in a very careful examination for the purpose of determining if they had resulted in a form of defective utterance.
