1st. Woman suffering with any wasting disease such a cancer or tuberculosis. (One of these days, and very soon we hope, it will be legally impossible for a tubercular or cancerous patient to become a mother.) 2nd. When a mother is the victim of any of the serious childbed complications such as convulsions, kidney disease, extensive loss of blood or blood poisoning, or runs a high temperature because of some disease occurring at the same time as the confinement, as, for example, appendicitis, scarlet fever, typhoid fever, etc. 3rd. Epilepsy, chorea, insanity, are also conditions which render artificial feeding necessary. It is much wiser immediately to put the child on artificial feeding if there is a justifiable reason for it than to experiment, because any experiment at this time is almost certain not to be in favor of the child. Artificial feeding is a comparatively easy and successful problem, provided it is begun with healthy digestive organs. If you keep the child at the breast of a mother whose milk is inadequate in quantity or quality, or both, for two or three days, and then begin artificial feeding, the child's stomach is already unable to perform its duty, and you have to treat it with the greatest degree of care and attention, and probably begin with a weak food, until you regain the lost ground. MOTHERS' MISTAKES IN THE PREPARATION OF ARTIFICIAL FOOD.--Another interesting condition which is quite common, is the tendency on the part of the mother to fail to follow instructions correctly,--even though written or printed,--regarding the preparation of the baby's food. When the baby is not thriving and gaining steadily in weight, or is fretty and cries a good deal, and does not rest and sleep peacefully, something, of course, is wrong. If, after a careful physical examination of the child, nothing is found to justify these symptoms, a physician invariably finds, if he questions the mother closely, that she has mistaken the instructions and is preparing the food wrongly. Infinite care in every little detail is the price of success in raising babies as well as in every other field of human endeavor. Revise carefully your method of preparing baby's food if there is any trouble such as is described above. Despite your absolute assurance that you are making no mistake, do not be surprised to find that you are not following directions to the letter, and because of this unintentional mistake, your negligence is responsible for your baby's condition. Go over the instructions with your husband, and let him follow your method of preparation, as you repeat it. He may detect the mistake if any exists,--two heads are always better than one. So important is this matter that the following two actual cases will demonstrate how easy it is to make a mistake, despite the absolute confidence of the mother, in each case, that she was following the printed directions correctly:
