MIXED FEEDING
In many instances, and particularly if the infant is under six months of age, and where he has had to have additional feeding from the bottle—under such circumstances the breast milk may be continued as "partial feeding," at least until the baby has reached his ninth or tenth month, at which time it may be wholly discontinued.
At each nursing time the baby empties both breasts, and the amount he draws may readily be estimated by carefully weighing him before and after each nursing. By referring to the directions in a previous chapter, the quantity of food needed for his size and age may be determined; while the deficit is made up from a bottle of milk containing properly modified cow's milk.
If the mother's health admits, or if the breasts continue to secrete a partial meal for the babe, mixed feeding should be continued until after the ninth or tenth month, when it can gradually be reduced from four or five times each day to once or twice a day, until it is finally omitted altogether. In the meantime, the baby is gradually getting stronger food and at eleven or twelve months the little fellow is able to subsist and thrive upon whole milk.
