The nursing-bottle must be kept perfectly clean; otherwise the milk will turn sour, and the child will be made ill. After each meal it should be emptied, rinsed out, taken apart, and the tube, cork, nipple, and bottle be placed in clean water, or in water to which a little soda has been added. It is a good plan to have two nursing-bottles, and to use them by turns.
Do not wean the child just before or during the hot weather, nor, as a rule, until after its second summer. If suckling disagrees with the mother, she must not wean the child, but feed it in part out of a nursing-bottle, on such food as has been directed. However small the supply of breast-milk, provided it agrees with the child, the mother should carefully keep it up against sickness: it alone will often save the life of a child when everything else fails. When the child is over six months old, the mother may save her strength by giving it one or two meals a day of stale bread and milk, which should be pressed through a sieve and put into a nursing-bottle. When from eight months to a year old, it may have also one meal a day of the yolk of a fresh and rare-boiled egg, or one of beef- or mutton-broth into which stale bread has been crumbled. When older than this, it can have a little meat finely minced; but even then milk should be its principal food, and not such food as grown people eat.
When an infant's bowels do not act, at least once or twice, freely, every day, sweet (olive) oil may be given, a teaspoonful at once; or manna, a quarter of a teaspooful at a time (it is sweet and easily taken); or simple syrup of rhubarb, a teaspoonful at once; or glycerine, a teaspoonful at a time. If the stomach is sick at the same time, magnesia may do more good, a quarter or half a teaspoonful, according to the age of the child, stirred well up in a little water. If colic is present, castor oil, a teaspoonful mixed with two teaspoonfuls of spiced syrup of rhubarb will be the best thing to open the bowels.
