DRYING THE SKIN.--The surface of the skin should always be carefully and thoroughly rubbed dry with flannel,--indeed, more than dry, for the skin should be warmed and stimulated by the assiduous gentle friction made use of. For this process of washing and drying must not be done languidly, but briskly and expeditiously; and will then be found to be one of the most effectual means of strengthening the infant. It is especially necessary carefully to dry the arm-pits, groins, and nates; and if the child is very fat, it will be well to dust over these parts with hair-powder or starch: this prevents excoriations and sores, which are frequently very troublesome. Soap is only required to those parts of the body which are exposed to the reception of dirt. NAPKINS.--The frequency of the discharges from the bowels and bladder requires a frequent change of napkins. A nurse cannot be too careful of this duty from the first, so that she may be enabled to discover the periods when those discharges are about to take place, that she may not only anticipate them, but teach the child, at a very early age, to give intelligent warning of its necessities. Thus a habit of regularity with regard to those functions will be established, which will continue through life, and tend greatly to the promotion of health. As the child grows older, the system of cleanliness must in no particular be relaxed, and it will be found the best preservative against those eruptive disorders which are so frequent and troublesome during the period of infancy. DURING CHILDHOOD.--When this period arrives, or shortly after, bathing is but too frequently left off; the hands and face of the child are kept clean, and with this the nurse is satisfied; the daily ablution of the whole body, however, is still necessary, not only for the preservation of cleanliness, but because it promotes in a high degree the health of the child. PLAN TO BE PURSUED WITH THE VIGOROUS AND HEALTHY.--A child of a vigorous constitution and robust health, as he rises from his bed refreshed and active by his night's repose, should be put into the shower-bath, or, if this excites and alarms him too much, must be sponged from head to foot with salt water. If the weather be very cold, the water may be made slightly tepid, but if his constitution will bear it, the water should be cold throughout the year. Then the body should be speedily dried, and hastily but well rubbed with a somewhat coarse towel, and the clothes put on without any unnecessary delay. This should be done every morning of the child's life.
