The energy developed in active childhood necessitates the consumption of a larger proportion of sugar than is required by adults. The craving of children for confections, candy, etc., furnishes a true indication of the actual requirements of nature, and it must be admitted that a certain amount of wholesome candy not only does most children no harm, but may serve them as an excellent food. The main difficulty with such forms of sugar, however, is that children are not furnished with a proper proportion of sugar with their meals, and the meals themselves are not so regulated as to prevent their becoming very hungry between times; consequently, if they can obtain candy, which satisfies them for the time, they are very apt to eat too much, with the result of producing more or less dyspepsia and diminishing the normal appetite. Alcohol in every form should be absolutely excluded. If given during early youth, it is particularly prone to develop a taste which may become uncontrollable in later years. (Children should not indulge in tea and coffee.) _Exercise._--As a general rule, active muscular exercise in children disturbs their digestive process far less than mental effort, when taken immediately after meals; and every adult is familiar with the romping which children can undertake straightway after dinner, often, though not always, with impunity, whereas a proportionate amount of exercise on the part of an adult might produce a severe dyspeptic attack. Much of the headache and inattention of pupils during school hours is the direct result of an ill-regulated diet, or from vitiated appetites. * * * * * INFANTS' DIET. One of the most important subjects included in a domestic science course of study is the feeding and care of infants. A subject requiring special intelligence and consideration; one which embodies the condensed information of the preceding chapters, and is the foundation upon which the future physical structure is built. It is not upon the mother alone that the baby depends for care and attention. Many young girls, especially elder sisters and nurse-maids, have this responsibility placed upon them when they are little more than children themselves. To these, as well as to young mothers, the following suggestions may prove helpful. The first demand of an infant is for food, and upon the quality and quantity of the article provided depends the health of the child, as well as the comfort of the household.
