WHY A BABY CRIES.--As has been stated, every healthy baby should cry for half an hour each day. Nature suggests, demands this as an essential exercise. Muscular movements involving a greater part of the whole body accompany the act of crying and furnish this necessary exercise. It is of great importance to an adequate and uniform development of the lungs; deep breathing is necessary to lusty crying, hence the lungs are expanded and the blood renewed and oxygenated. Crying is also of material aid in moving the baby's bowels. Babies in perfect health will, however, cry under any of the following circumstances, and doubtless under circumstances of lesser importance and frequency when frightened or uncomfortable from hunger or position, soiled napkins, inflamed buttocks, earache, pain, from heat or cold, unsuitable clothing, and during difficult bowel movement, when displeased or angry. Children slightly but painfully ill may cry incessantly for an hour or two. Thus, with intestinal colic, when the cry is loud and continuous until the child is relieved or until he falls asleep from exhaustion. The healthy, well trained child seldom causes trouble; it is the rule for it to be happy and good natured in its own way. THE HABITUAL CRIER.--If a child becomes a habitual crier, it is because it is uncomfortable and unhappy. There are restless, often vigorous, crying, whining infants, and the trouble, as a rule, is in the intestinal tract. Badly managed, "spoiled babies" cry from inattention, and when left alone. If they are taken up and talked to, the crying ceases, thus proving that it was not pain or discomfort that was causing the crying. In the case of the habitual crier we try to find out the cause of the bowel trouble and cure it; the spoiled infant we discipline rigidly, or leave it alone if its parents prefer that kind of baby. THE HABIT OF FEEDING BABY EVERY TIME IT CRIES.--The habit of regular feeding will, if persisted in and successfully established, render advice on this subject unnecessary. So also will the explanation of the evil of overfeeding have its effect on mothers. Apart from these reasons, however, the habit of feeding baby every time it cries is a pernicious one, and no doubt the mother, who will be striving to faithfully follow instructions, will have to overcome the advice of meddling friends who will regard it as a cruelty to allow the baby to cry. Do not give in to these busy-bodies; insist on attending to your own affairs, but be absolutely sure baby is not crying for a just cause. A child can only cry; that is its only language, but it cries for many things other than the nipple or the bottle. Examine it carefully,--a wet diaper a pin, an uncomfortable position, a drink of water, any of these may be the cause.
