A very common ailment in the modern nursery, especially among bottle-fed babies, is constipation. This is due entirely to improper diet. It can be permanently eradicated only through a change in diet. The child may be given temporary relief through the use of suppositories and massage, never through the use of violent cathartics. To secure an immediate movement of the bowels use an injection of sweet-oil, glycerine, or soap and water. To give the sweet-oil use a bulb syringe and one tablespoonful of the sweet-oil, warm. If glycerine is used, one-half teaspoonful may be mixed with one tablespoonful of warm water. If soap and water are used, make a warm suds of pure white soap, and inject about a teacupful. Glycerine suppositories, which can be bought at any reliable drugstore, act quickly, but they may also irritate the rectum. The best suppositories for use in chronic constipation in infants are the gluten suppositories, made by the Health Food Company. They act more slowly than glycerine suppositories, and the mother must not look for an action of the bowels for at least two hours. Neither injections nor suppositories should be depended upon for the permanent relief of constipation; they are makeshifts at best, and their continued use weakens the muscles of the rectum. The diet must be corrected and the causes of the trouble eradicated. An ailment which is frequently recurrent, and is a severe drain on the baby’s system, is the common every-day cold. In considering this illness, bear in mind that it is contagious. It can be prevented, first, by not allowing the child to come in contact with adults or other children who have colds, and, second, by keeping him in such fine physical condition that he can resist the infection when exposed to it. To harden the child against colds give him plenty of cool, fresh air. This means sleeping in a cool room; wearing light-weight clothing, so that he will not perspire; bathing in warm, not hot, water. The city child is apt to take cold because the nursery is heated by steam. The air is very dry; and this, in turn, dries the mucous membrane of the nose, and the air passages, leaving them susceptible to infection.
