Milk that has been sterilized, that is, bottled and put in boiling water for an hour, is not so good for the baby as pasteurized milk; that is, milk kept at something less than the boiling point for half an hour, since the higher temperature causes the milk to lose some of the qualities beneficial to the child.
Since cow's milk differs in its constituents from mother's, having more fat and less sugar, there will be need at first to modify the cow's milk, weakening and sweetening it somewhat. One good recipe for modifying cows' milk is: One part milk, two parts cream, two parts lime-water, three parts sugar water, the sugar water being made by putting two even teaspoonfuls of sugar of milk in a pint of water.
Condensed milk, which is often used as a substitute for cows' milk, is not nearly so good, since it has lost in the process of condensation one of the most important elements, that which forms bone tissue. Accordingly, babies fed upon condensed milk are apt to be "rickety," and they lack in general power to resist disease, which is primarily the mark of a baby fed on mother's milk, and to a slightly lesser degree, one fed upon cows' milk.
The stomach grows very rapidly during infancy, increasing from a capacity of one ounce soon after birth to eight ounces at the end of the year, and this should be taken into account by the increase of the amount supplied it. After the first week, a baby should increase in weight at the rate of one pound a month for the first six months. If he falls behind this rate and remains healthy, more sugar and fat may be introduced into his milk. If, however, he fails to gain weight and is sickly, the milk should be diluted and modified so as to make it easier of digestion.
Every mother should be warned against a common practice of starting the flow of milk from the nipple of the bottle by putting it in her mouth. Gums and teeth are rarely perfectly clean, and so form the favorite lurking place for disease germs, which, though they may not produce disease in the stronger body of the adult, may do so and often do so in the more susceptible physique of the child.
Just as the child was trained to the bottle while it was still taking the mother's milk, so it should be taught gradually to eat solids while it is fed upon the bottle. After the child has been weaned at the tenth month, he can be fed occasionally on broths or beef juice as a substitute for one of the milk feedings. The broth is more of a stimulant than a food, aiding digestion rather than supplying nourishment.
During the eleventh month, the yolk of a soft boiled egg, mixed with stale bread crumbs, may be added to the diet, together with a little orange juice or prune jelly. The latter will tend to keep his bowels free.
After twelve months, the child may be gradually accustomed to eat stale bread, biscuit or toast, broken in milk, thoroughly cooked oatmeal and similar cereals, baked potatoes moistened with broth, mashed potatoes moistened with gravy, and rice pudding. The pudding is made of two tablespoonfuls of clean rice, half a teaspoonful of salt, one-third of a cupful of sugar in five cups of milk. Bake in buttered pudding dish from two to three hours in slow oven, stirring frequently to prevent rice from settling.
At the age of two years and a half the child may be permitted to eat meat, preferably roast beef or mutton, cooked rare, or minced roast poultry.
Even though sugar is a very essential ingredient in the child's diet, it is very unwise to let it have this outside of its regular diet. Pure candy does not hurt the child by impairing its digestion so much as by interfering with its appetite for plain food. The child should never be allowed to form an inordinate appetite for anything, as this is certain to cause a corresponding deficiency elsewhere in his diet.
