When a child is suffering from fever, due to teething or indigestion, and in very hot weather, in addition to the regular morning bath it may have a sponge bath just before bedtime. This may be of plain, tepid water, or of water and alcohol—a quart of warm water to eight ounces of alcohol. Many mothers think that the daily bath is sufficient to provide for cleanliness in a child. This is a mistake. From the very start a child should learn that to be clean is to be comfortable. Particularly if the mother is careless about changing the diapers and the bedding, the baby will actually become accustomed to the discomfort which follows and will not resent it. If the diapers are changed immediately they are wet, the baby will cry bitterly when he is neglected and allowed to lie in a wet diaper or other clothing. At four months the healthy, normal baby should be trained to sit upon a small infant’s chamber at certain times in the day for the bowels to move. These chambers come in very small sizes and, as the baby is too small to sit alone, the mother holds the chamber in her lap and supports the baby with her arm or against her breast. When he is strong enough to sit up alone, the chamber is covered with a low, comfortable chair, which allows the feet to rest on the floor. The seat of the chair is protected by a rubber ring, which can be bought from any store where sanitary supplies for children are sold; this can be taken off and cleansed, and is a great improvement on the ordinary wooden seat. The use of a chamber of adult size is most undesirable for two reasons: it is so uncomfortable that the child cries and the movement is retarded rather than encouraged; and in the strained position certain organs may be displaced. It is best to use the little chamber and low chair twice a day, directly after the feeding in the morning and before going to sleep at night. When the child is older he will become accustomed to one movement of the bowels each morning. At eight months the mother should begin to train the child not to wet the diapers. To this end he is placed on the chamber or chair every hour, and in a surprisingly short time he learns, by training and instinct, that he can control the urine. The baby thus trained will never lie contentedly in wet or soiled clothing, and will develop into a child of cleanly habits.
