The science of infant-feeding has been revolutionized in the last twenty years, and, in the process, it has advanced too radically in many directions. Lately, the pendulum has been swinging backward, so that the most advanced knowledge of today probably represents a middle ground between extreme radicalism and extreme conservatism. In no other direction is this more manifest than in the feeding intervals. The religious adherence to the four-hour feeding interval is giving way to a more rational system. I am one of the firmest adherents of the longer interval: the food is better digested, the stomach has a period of rest, and the general well-being of the infant is better furthered than with more frequent feedings. But there are certain infants who do not receive enough nourishment in this interval, especially young breast-fed infants in whom it can be demonstrated by accurate weighing, before and after nursing, that they receive considerably more milk in twenty-four hours with the three-hour interval. This is the more important in that Rosenstern has demonstrated that a large proportion of infants up to the age of six weeks require more than the usual 100 calories per kilogram of body-weight. One hundred calories represents 150 grams of breast-milk, so that a five-kilo, or eleven-pound, baby should receive a minimum of 750 c.c. of breast-milk in twenty-four hours.
By far the best food for the healthy infant in every way—and this cannot be emphasized too strongly—is mother’s milk. There are certain alimentary disturbances in which it may be advisable to replace breast-milk with certain artificially prepared foods, such, for instance, as albumin milk in alimentary intoxication; but this is never true of the normally healthy infant. While, as regards growth and freedom from digestive disturbances, certain artificially prepared foods may, when used with exceeding care, produce as good results as breast-milk; nevertheless, this is only one function of breast-milk. The other function which can be imparted to no artificial food is the passive immunization of the child against infection. Ehrlich ( Zeit. f. Hyg. u. Infectionskr. , 1892, xii, 183) has proved that antibodies, antitoxin, and agglutinins are transmitted directly through the milk from mother to child; and it has been shown that the blood of a breast-fed child is considerably more bactericidal than the blood of a bottle-fed infant.
