Be sure and keep a good supply of pure and fresh air in the nursery. On this point Dr. Bell remarks, respecting rooms constructed without fire-places and without doors or windows to let in pure air from without, “The sufferings of children of feeble constitutions are increased beyond measure by such lodgings as these. An action, brought by the commonwealth, ought to lie against those persons who build houses for sale or rent, in which rooms are so constructed as not to allow of free ventilation; and a writ of lunacy taken out against those who, with the common-sense experience which all have on this head, should spend any portion of their time, still more, should sleep, in rooms thus nearly air-tight.”

After it is a month or two old, take an infant out to walk, or ride, in a little wagon, every fair and warm day; but be very careful that its feet, and every part of its body, are kept warm; and be sure that its eyes are well protected from the light. Weak eyes, and sometimes blindness, are caused by neglecting this precaution. Keep the head of an infant cool, never allowing too warm bonnets, nor permitting it to sink into soft pillows when asleep. Keeping an infant’s head too warm very much increases nervous irritability, and this is the reason why medical men forbid the use of caps for infants. But the head of an infant should, especially while sleeping, be protected from draughts of air, and from getting cold.

Be very careful of the skin of an infant, as nothing tends so effectually to prevent disease. For this end, it should be washed all over every morning, and then gentle friction should be applied with the hand, to the back, stomach, bowels, and limbs. The head should be thoroughly washed every day, and then brushed with a soft hair-brush, or combed with a fine comb. If, by neglect, dirt accumulates under the hair, apply with the finger the yelk of an egg, and then the fine comb will remove it all without any trouble.

Dress the infant so that it will be always warm, but not so as to cause perspiration. Be sure and keep its feet always warm; and for this often warm them at a fire, and use long dresses. Keep the neck and arms covered. For this purpose, wrappers, open in front, made high in the neck, with long sleeves, to put on over the frock, are now very fashionable.

It is better for both mother and child, that it should not sleep on the mother’s arm at night, unless the weather be extremely cold. This practice keeps the child too warm, and leads it to seek food too frequently. A child should ordinarily take nourishment but once or twice in the night. A crib beside the mother, with plenty of warm and light covering, is best for the child; but the mother must be sure that it is always kept warm.

Never cover a child’s head so that it will inhale the air of its own lungs. In very warm weather, especially in cities, great pains should be taken to find fresh and cool air by rides and sailing. Walks in a public square in the cool of the morning, and frequent excursions in ferry or steamboats, would often save a long bill for medical attendance. In hot nights, the windows should be kept open, and the infant laid on a mattress, or on folded blankets. A bit of straw matting, laid over a feather-bed and covered with the under sheet, makes a very cool bed for an infant.

Cool bathing, in hot weather, is very useful; but the water should be very little cooler than the skin of the child. When the constitution is delicate, the water should be slightly warmed. Simply sponging the body freely in a tub, answers the same purpose as a regular bath. In very warm weather this should be done two or three times a day, always waiting two or three hours after food has been given.

“When the stomach is peculiarly irritable, (from teething,) it is of paramount necessity to withhold all the nostrums which have been so falsely lauded as ‘sovereign cures for cholera infantum.’ The true restoratives for a child threatened with disease are cool air, cool bathing, and cool drinks of simple water, in addition to proper food, at stated intervals.”

In many cases, change of air from sea to mountain, or the reverse, has an immediate healthful influence and is superior to every other treatment. Do not take the advice of mothers who tell of this, that, and the other thing, which have proved excellent remedies in their experience. Children have different constitutions, and there are multitudes of different causes for their sickness; and what might cure one child, might kill another which appeared to have the same complaint. A mother should go on the general rule of giving an infant very little medicine, and then only by the direction of a discreet and experienced physician. And there are cases when, according to the views of the most distinguished and competent practitioners, physicians themselves are much too free in using medicines, instead of adopting preventive measures.

Do not allow a child to form such habits that it will not be quiet unless tended and amused. A healthy child should be accustomed to lie or sit in its cradle much of the time; but it should occasionally be taken up and tossed, or carried about for exercise and amusement. An infant should be encouraged to creep, as an exercise very strengthening and useful. If the mother fears the soiling of its nice dresses, she can keep a long slip or apron which will entirely cover the dress, and can be removed when the child is taken in the arms. A child should not be allowed, when quite young, to bear its weight on its feet very long at a time, as this tends to weaken and distort the limbs.
