When the baby is five or six months old, new milk should be added to any of the above articles of food, in a similar way to that recommended for boiled bread. (15.) For a delicate infant, lentil powder, better known as Du Barry’s “Revalenta Arabica,” is invaluable. It ought to be made into food, with new milk, in the same way that arrow-root is made, and should be moderately sweetened with loaf sugar. Whatever food is selected ought to be given by means of a nursing-bottle. If a child’s bowels be relaxed and weak, or if the motions be offensive, the milk _must_ be boiled. The following (16.) is a good food when an infant’s bowels are weak and relaxed: “Into five large spoonfuls of the purest water rub smooth one dessertspoonful of fine flour. Set over the fire five spoonfuls of new milk, and put two bits of sugar into it; the moment it boils, pour it into the flour and water, and stir it over a slow fire twenty minutes.” Where there is much emaciation, I have found (17.) genuine arrow-root a very valuable article of food for an infant, as it contains a great deal of starch, which starch helps to form fat and to evolve caloric (heat)—both of which a poor, emaciated, chilly child stands so much in need of. It must be made with good fresh milk, and ought to be slightly sweetened with loaf sugar; a small pinch of table salt should be added to it. I have given you a large and well-tried infant’s dietary to choose from, as it is sometimes difficult to fix on one that will suit; but remember, if you find one of the above to agree, keep to it, as a baby requires a simplicity in food—a child a greater variety. Let me, in this place, insist upon the necessity of great care and attention being observed in the preparation of any of the above articles of diet. A babe’s stomach is very delicate, and will revolt at either ill-made, or lumpy, or burnt food. Great care ought to be observed as to the cleanliness of the cooking utensils. The above directions require the strict supervision of the mother. Broths have been recommended, but, for my own part, I think that, for a _young_ infant, they are objectionable; they are apt to turn acid on the stomach, and to cause flatulence and sickness; they sometimes disorder the bowels and induce griping and purging. Whatever artificial food is used ought to be given by means of a bottle, not only as it is a more natural way than any other of feeding a baby, as it causes him to suck as though he were drawing it from the mother’s breast, but as the act of sucking causes the salivary glands to press out their contents, which materially assists digestion. Moreover, it seems to satisfy and comfort him more than it otherwise would do.
