Breast-fed infants rarely have intestinal diseases of a severe type. If they should develop diarrhea they must be taken off the mother's milk for twenty-four hours. They should be given a dose of castor oil or calomel and fed on barley water in the interval. The feedings should be reduced in quantity and the interval doubled. The two-hour interval will become a four-hour feeding: the three or four ounces at each feeding can be reduced to two ounces. The intention is to simply give as little as possible while the diarrhea is under way. The mother's breasts must be pumped at the regular feeding time in order to preserve the flow, release the pressure, and keep the milk fresh. It is sometimes a problem to renew feedings of milk without exciting a relapse of the diarrhea. It should not be tried until the stools are normal in color and consistency. This may not be for three or four days. In resuming the milk it should be given in smaller amounts and diluted with lime water or barley water for the first day. Gruels may be given to which skimmed milk may be added: later add the ordinary milk. If it is well digested and does not cause any return of the diarrhea, the quantity of milk can be slowly increased until the former feedings are resumed. It is often of very great advantage to boil the milk for some time. Peptonized milk is safe and can be used in bottle-fed infants after diarrhea. In older children, meat, broths, eggs, boiled milk, and dry toast bread may be used sparingly for some time. Cereals, vegetables, fruits, should be withheld for a considerable time and watched carefully when resumed. Kumyss, buttermilk, matzoon, bacillac, and other fermented milks are better borne than plain milk. All of these children need rest, fresh air, change of air, frequent bathing, and tonics, as an attack of this kind leaves them depressed, weak, languid, and anemic. SUMMARY:-- 1st. When a child complains of sharp, colicky, severe pains in the abdomen, around navel, which are shortly followed by foul, sour, frothy diarrhea,--greenish in color, it has acute intestinal indigestion. 2nd. Every mother should know that a green stool means danger. She should know to give at once a cathartic,--castor oil is good, but give a good large dose--then stop all food for twenty-four hours. If she learns this lesson she will have time to wait for the doctor; meantime, she may have saved her child's life. CHILDREN WITH WHOM MILK DOES NOT AGREE
