When about to feed the baby, the bottle is taken out of the ice box and heated to the desired temperature in a water bath. The temperature of the milk can be tested by allowing a few drops to fall on the wrist; it should feel warm, not hot; it should not be tasted by putting the bottle to the mouth of the nurse, or mother, as it may become infected by doing so. A flannel cover, or bag, should be made to fit the bottle and it should be put on while the baby is nursing so that the milk may retain its heat. The baby must not be disturbed while nursing, nor should he be jounced or carried around after nursing. These habits cause vomiting and indigestion. He should be put in his crib. WHEN TO INCREASE THE QUALITY OR QUANTITY OF FOOD.--Children of the same age may have different digestive abilities. A strong, robust child may be permitted to take a richer quality of milk than a weak, puny infant of the same age. If the quality or quantity of each feeding is too weak or small for the baby he will be dissatisfied and he will cry after the feeding. In such cases, if the bowel discharges are natural and yellow without curds or white specks, and if he is not gaining sufficiently in weight, the next stronger formula may be tried. If it is decided to put him on the stronger mixture, it is wise to cut the quantity down for a day or two in order to test out his digestive ability. If the stools remain good after three days, the quantity may be slowly increased until the amount in the recipe is allowed. It is a much more serious risk to overfeed the baby than to underfeed him. If too large a quantity is given, he may vomit it at once, or he may develop colic with intestinal indigestion. Such babies lose weight, become fretful and irritable, even though the appetite may remain good. If too strong a quality is given he may vomit sour, buttery-smelling milk, or have colic, and pass curds in the stool. If this happens it may be necessary to go back to a weak formula and work up from that standard. This is always a tedious and anxious experience and may lay the foundation for digestive disturbances for a long time. Don't be too anxious to increase the quality, or quantity, of your baby's food. It is much better to go slow and have a well baby, than to try to force matters and get into all kinds of trouble. No science calls for more elementary common sense, than the science of infant therapy. Digestive disturbances incident to this period are fully explained in the chapter on Diseases of Children.
