Sometimes it is due to the fact that the food is taken too rapidly, from too large a hole in the nipple. It may be due to too tight clothing, or to moving the child about in such a way as to press upon the stomach. _What are the principal causes of, and the changes in the food required by habitual vomiting, regurgitation, or spitting up of small quantities of food between feedings, often repeated many times a day?_ This is always a symptom of gastric indigestion, and a most troublesome one. In such conditions the fat and often the sugar also should be reduced and the lime-water increased. Formulas made from rich top-milk or milk and cream are to be avoided. Those made from 7-per-cent milk are less likely to be the cause of trouble than those from 10-per-cent milk; but if the symptoms are at all severe it is better to use instead of these the formulas of the Fourth Series derived from plain milk. Reduction in the sugar may be made by adding only one half ounce of milk sugar to each twenty ounces of the food; in severe cases the sugar may be omitted altogether. It is often advisable to double the amount of lime-water--i.e., use two ounces to each twenty ounces of food. The malted foods and all other foods containing much sugar usually aggravate the symptoms. The intervals between meals should generally be half an hour longer, and sometimes an hour longer, than when digestion is normal. The quantity given at a feeding should generally be less than with a normal digestion. Usually a smaller quantity of a strong food succeeds better than a larger quantity of a weak food. _What are the causes of, and food changes required by a constant and excessive formation of gas in the stomach, leading to distention and pain, or eructations (belching) of gas and often of a sour, watery fluid?_ This is often associated with habitual vomiting, and is due to similar causes, but particularly to the sugar, which should be greatly reduced or omitted entirely. _What changes should be made when there is habitual colic?_
