All baby feedings should be strained, as tiny lumps of food will clog the rubber nipple and the nurse may think the baby is not taking its feedings well. The following is a typical formula: Whole milk 15 oz. } Barley water 15 oz. } Sugar ½ oz. } 5×6×4 Flour ball ½ oz. } Boil two minutes. } Weigh the sugar and flour ball and make a paste with the barley water. Shake the whole milk, measure out 15 oz. in the graduate, and add the barley water mixture. Boil two minutes. Cool in running water, strain bottle and put on ice. The figures at the side mean that five feedings of six ounces each are to be given at four-hour intervals. It is necessary to cool all feedings as soon as modified, and keep them on ice for preservation until used. The only accurate way is to make up the whole quantity for twenty-four hours, put into separate bottles the exact amount of each feeding and give at the time ordered, after the bottle has been properly warmed. In warming the food, care must be used to get it neither too hot nor too cold; 100° F., or when it feels warm to the back of the hand, is about right. The child should be held in the arms while taking the bottle. A buttermilk feeding must not be heated to more than 100° F. because it curdles and can not be used. =The rubber nipples= should be washed thoroughly after use, boiled once a day, and kept in boric acid solution. =The necessary articles= for home modification of milk can be obtained anywhere. One set of utensils should be kept for this purpose exclusively and boiled each time before the food is prepared. A list is convenient: A 16 ounce glass graduate. One tablespoon and one teaspoon may be used for measuring purposes, if unable to get a satisfactory scale. 1 2–quart aluminum cooking dish. 1 long-handled aluminum spoon. 1 fine wire mesh strainer, thirty holes to the inch. 1 dozen bottles, 5 ounce size if the child is small, and 10 ounce if the child takes large feedings. The bottles should have wide mouths, straight sides, and round bottoms, which clean easily. Paper caps or corks that fit tightly should be used instead of cotton stoppers. Close rubber caps are best, for, as the milk cools, a vacuum is created, the rubber is drawn in and the milk remains air-tight until opened. If infants are kept on a milk diet alone for too long at a time, they do not thrive so well, hence as early as six months, other things may be given. At this stage, the most desirable additions to the food would be cereal, farina or cream of wheat, orange juice, vegetable broth, toast crumbs, etc. The administration of orange juice should be started when the child is only a few weeks old.
