No soap should be used while the baby has prickly heat and after the bath he should be patted thoroughly dry and powdered with some such soothing powder as the following: Powdered starch one ounce Oxid of zinc one ounce Boracic acid powder 60 grains [Illustration: FIG. 60.—Method of holding the baby in the tub to keep all but his head covered, in giving a bran, starch, soda or mustard bath. ] =Diarrhea.= If your baby has an increase in the number of his movements, or if they become watery in character, something is wrong. It may be only a mild disturbance or it may be the beginning of an attack of summer diarrhea, and as at first you cannot possibly tell which it is, you must not take it lightly. Notify your doctor at once, but if you are remotely situated or he is delayed in communicating with you, there are certain helpful things that you can do for the baby while waiting for the doctor. The first is to give an enema of half a pint of water, at 110° F., containing ½ teaspoonful of salt. (See Fig. 64, page 217, for method of giving enema.) If the baby seems to have only a slight diarrhea it may be enough to reduce his food one half, whether he is breast-fed or bottle-fed, and to give him an abundance of cool boiled water to drink. If he is bottle-fed it is a wise precaution to make up his formula with skimmed milk and leave out the sugar. [Illustration: FIG. 61.—Putting the baby into a wet pack. ] If the baby has frequent loose movements; seems feverish; vomits and cries as though he had pain, stop all food and give nothing by mouth but water, until the doctor comes. If you care for your baby, yourself, through an attack of summer complaint you will find that the doctor’s instructions are directed toward keeping the baby cool, clean and quiet, while he, himself, gives very careful attention to the question of feeding. It is clear, then, that the baby should be lightly clad and kept quiet and undisturbed, in a cool shady place, out of doors as much as possible. During the warmest part of the day, however, he will often he better off in the house, in a room with the shutters closed. But while keeping the baby cool, you must bear in mind the harm that may be done by chilling him or exposing him to a cold draft or wind. The doctor may want him to have several baths daily, possibly tub baths, at a temperature of 100° F., or cool sponge baths. Packs, also, are given, for they not only cool the baby but quiet him as well, if he is restless. These packs may be cool (80° F.); tepid (100° F.) or hot (105° to 108° F.) according to the baby’s needs.
