During acute illness in infancy from any cause, and especially in fevers, there is a temporary partial or complete cessation of the function of digestion and assimilation, and the food should be materially lessened. Nature commonly meets this indication most vigorously by establishing anorexia, vomiting, and diarrhea that limit the taking and the assimilation of food. Intoxication is especially to be avoided along the lines indicated under that heading. Sugar, and especially fat, are to be used with caution. Fat-free milk, albumen water, farinaceous drinks, and in older children broths and fruit juices, may be given freely. On account of the high tolerance for human milk and because of its specific properties, breast feeding is safely continued. Except in weak babies that can nurse only a small amount, the interval between nursings should be long, at least three, better four, hours, and it is often wise to limit the time of nursing.
