Stays or corsets may be used, in a proper manner, during the first five or six months; they should be moulded to the shape of the changing figure, and must not depress the nipple or the enlarging breasts. The garters ought to be worn slack; tight garters are very injurious, and if the veins are enlarged or varicose, it will be necessary for her to wear an elastic silk stocking. _Moderate_ exercise in the open air is proper during the period of pregnancy, and walking is a good kind of exercise; but very long walks, and dancing, ought not to be indulged in. Riding in a wagon over rough roads, and railway traveling, are objectionable. BATHING should be practiced with great care. A warm bath is too relaxing; a tepid bath once a week is beneficial. Sponging the body every morning with lukewarm water may be practiced, and the skin should be quickly dried with a coarse towel. The temperature of the water may be reduced gradually until it is quite cold. A sitz bath may be used every morning, although it is best to sit in it but a few seconds. If it gives a slight shock, it will be immediately followed by an agreeable glow. Put a little warm water with the cold at first. Ventilation is of the utmost importance. During the day time, the windows in every unoccupied room in the house ought to be thrown open. Attention should be directed to keeping the atmosphere in the sitting and sleeping rooms of the house fresh. Many poor people sleep in a very small, close bedroom, and breathe an air that is really poisonous. The lady should see also that the house is kept light, that the drains are in good and perfect order; that the privies are frequently emptied of their contents, and that the drinking water supply be not contaminated. SLEEP, by its sedative influence, and by the calmness of all the functions that attend it, has a favorable influence upon the disturbed nervous system of the mother, and upon the growth of the fœtus. Her bedroom ought to be large and airy, and she should not have curtains closely drawn about her bed. The windows of the room should be opened during the day; the bedclothes should be thrown back, and everything ventilated; the bed must not be loaded with clothes, and the bedroom at night should be dark, and as far as possible from noise. These things will tend to secure sleep; but if the pregnant woman should still be restless, and feeling oppressed and hot, she should perhaps admit more air into the room. Let her also attend every day to her bowels, that they be not allowed to become costive; perhaps eat cooling fruits, live on an abstemious diet, and if there is a feeling of faintness when she attempts to lie down, she should have a bed so arranged that her shoulders and head are elevated.
