"On waking in the morning, the child must make a practice of getting up at once, instead of ruminating in bed. Parents must avoid criticising her about trifles, and her behaviour must be left to take care of itself at present. Her affections should be indulged and reciprocated. She must be given plenty to do and sent back to school in a few days."
Under this treatment the girl's disposition began immediately to improve. Within two weeks her mother reported to Doctor Williams that she was as "happy and joyous" as she had formerly been. No longer was her stomach being loaded with food it could not digest; and with the removal of this source of toxic irritation, together with the suggested changes in her parents' handling of her, she had become a different child.
On the other hand, underfeeding may be, and often is, a cause of sulkiness, owing to the inadequate nourishment the underfed child's brain receives and the general weakness of his system. Sulkiness, again, may be associated with an insufficiency of physical exercise, or with failure to make sure that the child's living and sleeping quarters are properly ventilated. Fresh air is as essential as digestible food to the maintenance of nervous balance. When, as sometimes happens, children are obliged to spend their school hours in dusty, ill-ventilated classrooms, when they return to homes with few windows, and these seldom open, and when they sleep in a tainted, vitiated atmosphere, it is indeed hard for them to see life in bright colours. Besides which, to prevent or cure sulkiness in a child, it is not enough to keep school and home well ventilated, and let the child play outdoors as much as possible. It is necessary also to see to it that the child is so conditioned that he will have no difficulty in adequately breathing the fresh outdoor air.
To a physician in a Western city there was brought a boy, nine years old, with a face so flat, expressionless, and frog-like, that persons who knew him thought he was feeble-minded. His school teacher reported that his mind seemed a blank and that he was also hard of hearing. His parents complained that he was selfish and sullen. The boy seemed doomed to a life of misery.
But, making a physical examination of him, the doctor found reason to think otherwise. He discovered no real brain defect. In the cavity back of the boy's nose he found an abnormal growth of adenoid-tissue that of itself might account for the boy's stupidity and sulky disposition, as well as for his deafness. The diseased tissue acted as an irritant and a drag on his nervous energy; and, in addition, by interfering with the intake of oxygen it lowered the nutrition of the brain.
The adenoid growth was removed. Gradually the appearance of the unfortunate boy's face changed for the better. His hearing improved. He began to take an interest in school work, and studied to real advantage. Consideration for others took the place of his habitual selfishness, and he sulked no more.
Adenoids, dullness, deafness, and sullenness often are intimately associated. The parents of a sulky child will therefore do well to ascertain whether adenoid trouble is present. Its presence is usually plainly indicated by the flat, insipid appearance of the victim's face and by his habit of breathing through his mouth, particularly when asleep. If there is any reason to suspect adenoids, parents should take their children to a competent physician without delay.
Further, and on general principles, they should have their children's teeth thoroughly examined by a good dentist. A child whose teeth are decayed is a child suffering both from nerve irritation and from some degree of poisoning, due to his swallowing food that has become infected by its contact with the germs of dental caries. Such a child has abundant reason to feel uncomfortable, pessimistic, and sullen. So has a child whose teeth, if not decayed, are crowded together.
Yet another common, and often unsuspected, physical cause of sulkiness in children is eye-strain. Most of us are under the impression that when a person is afflicted with eye-strain he is certain to have painful or, at least, unpleasant sensations in his eyes. This is by no means always the case. During childhood and youth there may be no telltale eye symptoms at all. But defective eyesight may give rise to various nervous conditions; sulkiness is one manifestation.
An eight-year-old girl, previously in good health, and with no more nervousness than is displayed by the average child, began to show traits that worried her parents. She became difficult to control, querulous, and sullen to an extent that bordered on melancholia. In addition, she complained of indigestion and headache, symptoms which caused her parents to take her to a physician for treatment. His medicines and the course of diet he prescribed did her no good, and another physician was consulted. Then began for this unfortunate little girl a weary round of examinations by doctor after doctor. Every means of curing her headaches and indigestion seemed unavailing, and her nervousness and sullenness increased apace. Finally, one physician, in spite of the fact that the girl's eyesight seemed normal, suggested that she be examined by an eye specialist. Then, for the first time, it was discovered that she had a serious ocular defect. According to Doctor Percy R. Wood, who reported the case for the benefit of the medical profession in general, within six months after she first put on spectacles the girl was entirely free from digestive disturbances, her head had ceased to ache, and her melancholy moroseness had given way to normal good nature.
