If the vomiting is wrongly interpreted and overfeeding is continued, either the baby dies or the stomach establishes a toleration, passing the trouble on to other parts of the body. One organ never suffers long alone. The circulation passes the disease on to other parts, assisted by the sympathetic nerves, which are present in all parts of the body.
When the stomach has established its toleration, several things may happen, only a few of which will be discussed, for the process is essentially the same, though the results appear so different. In infants whose digestive power is not very strong the excessive amount of milk curdles, as does the part that is digested. The water of the milk is absorbed, but the curds pass into the colon without being digested and they are discharged in the stool as curds. They are partly decomposed on the journey through the alimentary canal, producing poisons, a part of which is absorbed. A part remains in the colon, making the bowel discharges very offensive.
The passage of curds in the stool is a danger signal indicating overfeeding and should be heeded immediately. If it is not, the chances for a ease of cholera infantum, especially in warm weather, are great. Cholera infantum is due to overfeeding, or the use of inferior milk, or both. It is a form of milk poisoning, in which the bowels are very irritable. As a matter of self-protection they throw out a large quantity of serum, which soon depletes the system of the poor little sufferer, and death too often claims another young life. If cholera infantum makes its appearance the baby is given its best chance to live if feeding is stopped immediately, warm water given whenever desired, but not too large quantities at a time. Give no cathartics, for they irritate an already seriously disturbed mucous membrane, but give a small enema of blood-warm water once or twice a day. Keep the baby comfortable, seeing that the feet and abdomen are kept warm, but give plenty of fresh air. Medicines only aggravate a malady that is already serious enough. This disease is produced by abuse so grave that in spite of the best nursing, the baby often dies. It is easily prevented.
Strong babies with great digestive power are often able to digest and assimilate enormous quantities of milk, several quarts a day. They can not use all this food. If they could their size would be enormous within a short time. They do not find it so easy to excrete the excess as to assimilate it. The skin, kidneys, lungs and the bowels find themselves overtaxed. Often the mucous membrane of the nose and throat are called upon to assist in the elimination. These are the babies who are said to catch cold easily. Their colds are not caught. They are fed to them. This constant abuse of the mucous membrane results in inflammation, subacute in nature, or it may be so mild that it is but an irritation. The result in time may be chronic catarrh or thickening of the mucous membrane of nose and throat. While the catarrh is being firmly established adenoids are quite common.
In other cases too much of the work of excretion is thrown upon the skin. The same thing happens to this structure as happens to the mucous membrane. It is made for a limited amount of excretion and when more foreign matter, much of it of a very irritating nature, is deposited for elimination through the skin, it becomes inflamed. It itches. In a little while there is an attack of eczema. The baby scratches, digging its little nails in with a will. The infant soon has its face covered with sores and the scalp is scaly. The proper thing to do is to reduce the feeding greatly. Then the acid-producing fermentation in stomach and bowels will cease, but enough food to nourish the body will be absorbed, the skin will have but its normal work to perform, the cause of the irritation is gone and the effects will disappear in a short time. Two weeks are often sufficient to bring back the smooth, soft skin that every baby should have. The sufferers from these troubles are almost invariably overweight, and the parents wonder why their babies, who are so healthy, should be troubled thus!
Mothers owe it to their nursing babies to lead wholesome, simple lives. It is not always possible to live ideally, but every mother can eat simply and control her temper. Wholesome food and equanimity will go far toward producing healthful nourishment for the child. Stimulants and narcotics should be avoided. Meat should not be eaten more than once a day, and it would be better to use less meat and more eggs or nuts. Fresh fruits and vegetables should be partaken of daily. They are the rejuvenators and purifiers. The cereal foods should be as near natural as possible. The bread should be made of whole wheat flour mostly. If rice is eaten it should be unpolished. Refined sugar should be taken in moderation, if at all. The potatoes are best baked. Pure milk is as good for the mother as it is for the child. Highly seasoned foods or rich made dishes should be avoided. In short, the mother should live as near naturally as possible.
The importance of cheerfulness can hardly be overestimated. A nervous mother who frets or worries, or becomes mastered by any of the negative, depressing passions, poisons her babe a little with each drop of milk the child takes.
Some mothers are unable to nurse their babies. This is so because of lack of knowledge principally, for women who give themselves proper care are nearly always able to furnish nourishment for their infants. It may be that this function will be largely lost if the present preponderance of artificial feeding continues, and if various inoculations are not stopped. Some mothers find it a great pleasure to nurse their babies. Others refuse to do so for fear of ruining their figures.
No matter what the reason is for depriving the infant of its natural food, the parents should realize that its chances for health and life are diminished by this act. If intelligence and care are used in raising the bottle-fed babies only a few will die, in fact none will die under the circumstances, provided they were born with a normal amount of resistance. So it behooves parents of such babies to be extremely careful. That there are difficulties in the way, or rather inconveniences, can not be denied, but there are no insurmountable obstacles.
The best common substitute for mother's milk is cow's milk. If clean and given in moderation it will agree with the child and produce no untoward results.
