Under the most favorable conditions we meet a constant resistance to life, and the higher we ascend in the scale of civilization the greater is the resistance encountered. It is therefore the duty of the mother, as also of the father, to remove every obstacle that would offer resistance to the physical and mental growth of the child. In order to do this it is necessary to carry out certain well-established laws concerning diet, exercise, fresh air, sunshine, and mental training. GENERAL RULES FOR THE PROSPECTIVE MOTHER From the time conception is recognized the following general rules should be observed: 1 The corset or all tight-fitting garments that would in any way interfere with freedom of exercise and thorough development of the abdominal muscles should be discarded. 2 As much time as possible--at least two hours each day--should be spent in the open air, and a system of moderate trunk exercises followed, together with deep breathing, calculated to expand the lungs to their fullest cell capacity, which is Nature's method of burning or oxidizing waste matter, and thereby keeping the blood pure. 3 The mental occupation should be an important factor in the daily regimen. Some congenial study should be chosen with the view of making it useful, while some remunerative employment should be sought and indulged in for a portion of each day. Avoid idleness by all means, or an idle roaming of the mind and spirit. Learn to think, to concentrate, to work, and to do something for others, as it is from these things that all happiness is gained. 4 The diet of the future mother should be governed somewhat by the laws laid out in the first part of this lesson; that is, age, temperature of environment, and occupation should be considered in its selection. SPECIAL RULES FOR THE PROSPECTIVE MOTHER [Sidenote: Suggestions for the diet] There are some specific rules in regard to diet, however, which every mother should observe. The diet should be balanced so as to contain all the needed elements of nourishment in approximately the right proportions. The proportions, however, should differ in many cases from that which she would take if she were in a normal state, especially in regard to starchy foods or calcareous matter. An abundance of green salads, sweet ripe fruits, fresh vegetables in season, eggs, milk, nuts, and not more than two ounces of bread, potatoes, or dried beans should be taken daily. If flesh food or something salty is craved, tender chicken, or fish, may be allowed in small quantities. [Sidenote: Abnormal appetite during pregnancy]
