It is soft, yellow, and smooth, containing no lumps. _When are the stools dark brown or black?_ While taking bismuth, iron, and sometimes when taking much meat or beef juice; also while taking many of the prepared foods. They may be dark brown or black from blood. This last is a condition which may indicate serious illness. _How may a child be trained to be regular in the action of its bowels?_ By endeavouring to have them move at exactly the same time every day. _At what age may an infant be trained in this way?_ Usually by the second month if training is begun early. _What is the best method of training?_ A small chamber, about the size of a pint bowl, is placed between the nurse's knees, and upon this the infant is held, its back being against the nurse's chest and its body firmly supported. This should be done twice a day, after the morning and afternoon feedings, and always at the same hour. At first there may be necessary some local irritation, like that produced by tickling the anus or introducing just inside the rectum a small cone of oiled paper or a piece of soap, as a suggestion of the purpose for which the baby is placed upon the chamber; but in a surprisingly short time the position is all that is required. With most infants, after a few weeks the bowels will move as soon as the infant is placed on the chamber. _What advantage has such training?_ It forms the habit of having the bowels move regularly at the same hour, which is a matter of great importance in infancy and makes regularity in childhood much easier. It also saves the nurse much trouble and labour. SLEEP _Should a child sleep in the same bed with its mother or nurse?_ Under no circumstances, if this can possibly be avoided. Very young infants have often been smothered by their mothers, by overlying during sleep. If the infant sleeps with the mother, there is always the temptation to frequent nursing at night, which is injurious to both mother and child. Older children also should, if possible, have separate beds; many contagious diseases and bad habits are contracted by children sleeping together. _How should an infant's bed be prepared?_ The mattress should be firm but soft, the pillow very thin, and the covering not excessive. A baby should not be allowed to sleep always in the same position, but should be changed from side to side. Hair pillows are useful in summer and for children who perspire very much. _How much sleep is natural for a newly born baby?_ A baby with a good digestion and proper food will usually sleep at this period about nine tenths of the time. _How much should a baby sleep at six months?_ About two thirds of the time. _Up to what age should an older child take a nap during the day?_ Always until four years old, and if possible longer. _At what age may an infant go all night without feeding?_
