As puberty approaches, a mother should give her daughter adequate information so that she should not be frightened at the first appearance of the menstrual flow, nor take any risks at this period. Menstruation is the sign of the possibility of motherhood. If properly taught this fact, every girl will be glad she menstruates and will want to be careful during the period. On account of lack of early instruction, many a girl obtains wrong ideas regarding this function and it produces in her a feeling of repugnance. She should be taught the reasons for observing prudence during the menstrual period. The possible lifelong invalidism that may result should be pointed out. A woman owes it to herself to take good care of herself during her menstrual periods. For two or three days at least she should avoid any unnecessary strain, lie down and rest as much as possible and not worry over school or other duties. Especial attention should be paid to cleanliness during this period. A sponge bath taken in a warm room is not injurious and unpleasant odors can be avoided by sponging the parts with a warm antiseptic solution upon changing the cloth. Every woman should be provided with a circular girdle cut upon the bias so it may be elastic, and provided with tabs to which to pin the folded cloth. She also should have a supply of sanitary cloths made of absorbent cotton-fabric, or pads made of absorbent cotton enclosed in gauze. The latter especially are convenient for the girl who is obliged to room away from home, for they may be burned and the cost of new ones is no greater than the laundry of cloths. These pads or cloths should be changed at least twice a day. It also is necessary that one should bathe the parts in warm water with each change, as unpleasant odors can thereby be avoided. At the close of each period she should take a bath and change all clothing. One cannot be too careful about these matters so essential to cleanliness. It is surprising how many women neglect these important matters. The erroneous idea that bathing of any sort at this time may have disastrous results accounts for much of this neglect. If proper care is taken warm sponge baths cannot be injurious. A woman in normal health should not suffer at the menstrual period. She normally will have a feeling of lassitude and disinclination for any great mental or physical work, perhaps accompanied by a slight feeling of uneasiness in the pelvic region. Because so many women do suffer at these periods it often is considered as "natural" and allowed to continue. The phenomena often noted at the menstrual period are,--pains in various parts of the body, hot flashes, chilliness and various hysterical symptoms. A few days before menstruation commences there may be various nervous symptoms, as irritability and a disinclination for any exertion. Dark circles often appear under the eyes and the breasts become enlarged and painful. A sense of fullness and oppression may be felt in the head.
