During the summer the outer clothing should be made of the thinnest quality of material possible, and the underclothing of the finest flannel or gauze. Body heat may be maintained during changes of temperature by extra outer wraps--not by dressing the baby in clothes that keep it too hot and uncomfortable all the time. The main object to be attained in clothing the baby is to ensure a sufficient protection, but the clothing must be light, warm, loose, and non-irritating. Don't bundle up the arms and legs so that they cannot be moved; don't pin them so tight that the child cannot breathe properly and don't put the band on so that the child is in torture all the time from inability to move the abdomen. BABY'S NIGHT CLOTHES.--The night clothing should be the same as that worn during the day, but it should be loose and of the lightest flannel material. For older children a thin woolen shirt (not the one worn during the day) and a suit of union clothing with feet is best. The mistake must not be made to cover children too warmly at night. They can do with relatively less than adults. Too much covering will render the sleep restless, will encourage nightmare, and in older children will engender bad habits. Delicate children especially must not be over-covered at night. For the first few months children should sleep in a darkened room. CARE OF THE EYES.--The eyes should be cleansed for the first few days with a saturated solution of boracic acid. They should be protected from the direct light for two or three weeks after birth. CARE OF THE MOUTH AND FIRST TEETH.--Boiled cooled water should be used to cleanse the mouth every morning after the bath. A soft piece of sterile gauze should used for this purpose. The mother must guard against using too much force in cleaning the mouth of an infant. The milk teeth should receive attention. If they are allowed to become dirty they will become carious and cause bad breath and neuralgia. Teeth of this character are a menace to health because they harbor germs and in this way infect the mouth and cause stomach troubles. Teeth that are carious should be filled or removed. CARE OF THE SKIN.--The skin of a baby, because of its delicate character, is susceptible to the slightest changes in the weather or to the condition of the digestive organs. Babies are frequently subject to rashes, intertrigo, excoriations, eczema, and other skin affections. It is much easier to prevent these conditions than to cure them. Cleanliness, not only in giving a daily efficient bath, but in every other respect, is essential. Castile soap only should be used, and no rubbing indulged in, simply mopping the parts with gauze well saturated with soapy water. All napkins should be removed as soon as soiled. If the skin is easily chafed the child should be bathed in salt water or water in which bran is mixed as explained in the chapter on bran baths.
