Sterilized (Pasteurized) Milk.—During epidemics of dysentery, diarrhœa, typhoid fever, scarlet fever, and diphtheria, as well as in those instances where it is suspected that the cow is not healthy, or where the milk has to be kept for considerable periods of time, it is well to sterilize it by heating. The most effective method of accomplishing this is by boiling the milk for an hour or so, but inasmuch as it is believed to be then not quite so wholesome as when less heat is employed, a process known as pasteurization is frequently used; this consists in heating the milk for thirty minutes to from 155° to 160°F.,—such temperatures killing all of the ordinary germs, but not altering the milk so completely as when it is boiled.
Peptonized Milk.—It now and then happens that children fail to thrive where all of the precautions heretofore referred to have been strictly adhered to, and under such circumstances good results are frequently secured by subjecting the milk to a process known as peptonization. This consists in the addition of a digestive ferment, obtained from the pancreas of lower animals, together with ordinary cooking-soda. In carrying out the process the milk, whether whole or modified, is placed in a clean bottle, and the peptonizing powder added after having been rubbed up with a teaspoonful of milk. The container is then placed in a pitcher of water at a temperature of 110°F., which is about as warm as the hand can bear comfortably, and is here left for from ten to twenty minutes if only partial peptonization is desired, or for a couple of hours should it be wished to complete the process. The peptonized milk may be prepared at each feeding, or the whole amount for the day may be made at one time in the morning; in the latter case, where it is desired to have the milk only partially peptonized, the ferment should be destroyed by boiling after it has been allowed to act for from ten to twenty minutes.
Feeding after the First Year.—As the infant is weaned other food should be gradually added; this should still consist largely of milk, to which some time later may be added gruels prepared from well-cooked oats or barley, beef-juice, or the white of an egg slightly cooked. The various broths may also be allowed. Children relish very much all fruit-juices, and they may be given in moderation without harm, and even with benefit in many cases. As the child grows older, the various cereals should form a greater and greater proportion of its diet, but due care should be exercised in always seeing to it that they are thoroughly cooked; in order to be digestible for children such substances should be cooked at least three or four hours before eaten.
General Hygiene of Infant Life.—In order for children to be healthy, the greatest regularity is necessary in their habits. They should arise at a certain hour in the morning and go to bed at a fixed time at night. Their clothing should be loose, and not too tight fitting, and should at all times correspond to the state of the weather. Nothing is more common, and nothing produces irritability, loss of sleep, and even serious general disturbances in infants, more frequently than too much clothing. It is generally customary to use from the time of birth and during the period of infancy a flannel band around the child's abdomen. Just how this acts is not clear, but there seems good reason for the belief that in some unexplained way the practice has the effect of warding off intestinal disturbances, and is, therefore, to be recommended.
Napkins should be changed when soiled, and then should be immediately placed in water, in which they should remain until washed out; under no circumstances should they be left lying around the nursery.
When the weather permits, the child should be kept as much out-of-doors as is possible. For the first few days of the infant's life, particularly if the weather be cool, it should, of course, be kept indoors, but even then free access of air should be allowed. There is no objection whatever to the infant sleeping out-of-doors—in fact, where this is feasible, it generally shows improvement as soon as the practice is commenced. When out-of-doors, it is of course necessary to see that the sun does not shine directly into the infant's face, and wetting should, of course, be avoided; also the hood of the carriage should be arranged to prevent strong winds from blowing on the child.
The nursery should be well aired, a window being left up at night except during severe weather.
Sleep.—Nothing is more important for the proper development of a child than for it to have an abundance of sleep. During the first few months of its life it sleeps practically all of the time—the period becoming gradually lessened as it grows older. Infants should be suffered to sleep just as much as is possible, it being not only unjustifiable but absolutely criminal to interfere with them in this particular in the slightest degree. Not only is it necessary that infants have all the sleep that they desire, but it is true throughout childhood, a fact to which many foolish parents seem utterly oblivious. How often do we see a child scarcely more than an infant aroused in the morning and sent off to school, and how frequently do we hear misguided parents boast of their inflexible rules in enforcing such evil practices. Truly man comes hard by the knowledge that nature is much wiser than he, and the vast majority never learn the fact at all.
As soon as the child is able to crawl, it should be placed on a clean quilt or blanket on the floor, and allowed to move about to its heart's content. When it is able to walk, allow it to run about and play to its full capacity—as in such exercises consists the great school of its physical being, the school upon which will depend its strength and health in after life. Allow the child to keep up his play as long as he has any inclination to do so, and never be so foolish as to confine him in the house when he wishes to be out under the blue heavens, for here only will it be possible for him or her to develop into a real man or woman. Allow this to go on until the child of its own accord comes and asks to be taught other things, for not until then is its outside education nearing completion, and not until then is it possible for him to take interest in and learn things connected with books. No boy should ever be sent to school before he is twelve or fourteen years of age; girls, on account of their maturing earlier, may begin a couple of years sooner.
The whole science and art of properly raising children consists in feeding them good clean food in proper amounts, in never allowing them to be awakened, and in permitting them to play in the open air to their hearts' content.
