Cases of ordinary colic are usually relieved by heat to the abdomen and feet, drinking hot water in which there has been dissolved a pinch of ordinary baking soda, or a portion of a soda mint tablet, or by the use of the photophore, as previously described. The treatment of such ordinary colic need not be given further consideration here because it has been described at length in a former chapter; but we do call the attention of the mother to a more serious form of recurring colic which so often accompanies chronic intestinal indigestion, marasmus, and malnutrition. In most instances the food is radically at fault and should be reduced to a mixture which can more readily be digested and assimilated by the child. Often whey mixtures, peptonized foods, or buttermilk may be indicated. The weight of the baby, the age of the baby, and the color of the stools, must all be taken into account in the preparation of this easily digested food. Weak mixtures should be given at first and then gradually and carefully the quality may be strengthened until the normal formula is again used for the baby. Injections into the bowel of water, to which has been added one level teaspoon of soda to the pint, will often give relief in this form of colic. CHRONIC INDIGESTION While this condition may occur at any time during babyhood days, it often makes its appearance during the last half of the first year and up to the fifth year. It is accompanied by mucus in the stools, chronic flatulence, constipation or diarrhea, or the alternating of the two, restlessness at night, distention of the abdomen ("pot bellied") accompanied by pain, a coated tongue with a fetid breath, and loss of appetite. It is a pitiable picture--the weight is usually reduced and the child gives the appearance of being decidedly undernourished. This condition is usually occasioned by errors in diet, whether it be over-feeding or feeding of the wrong element of food, and, since the diet is usually responsible for the condition, in the line of treatment diet is a prime factor. All fats must be taken from the food, sugars should be avoided, and the amount of starchy foods, such as flour, potatoes and bread, should be greatly reduced. Buttermilk, skimmed milk, eggs, green vegetables, and fruit juices should be given. In the older child, if grains are used, they should be well toasted or baked. JAUNDICE
