Whole milk 36 ounces Boiled water 12 ounces Sugar of milk 4-1/2 level tbs.
From this point on the formula may be increased by replacing the boiled water with whole milk, two ounces each month up to thirteen months. At this age the boiled water may be omitted from the formula one ounce each week. Beginning at the age of eight months the sugar may be eliminated from the formula, one tablespoonful each month.
_Barley Water._--At the age of five months, or at any time thereafter, barley water may be substituted for boiled water in the formula. This should be substituted when the baby is not gaining in weight. It may be substituted in many instances when the movements are not well digested.
_Lime Water._--It is frequently found to be advisable to add lime water. It is not necessary in every instance, but should be given if the baby is inclined to spit up, or in cases where the stools are too frequent in number and are slightly green in color.
~Determining the Fuel Value of a Formula.~--The computation of the fuel value of a formula is very essential since the growth and development of the infant depends largely upon whether or not its energy expenditures are well covered. The method is simple, requiring the same methods used in the computing of other dietaries. Take the formula just calculated, its fuel value would be estimated as follows: Thirty-two ounces are equal to 960 grams. In each 100 grams there would be 3 grams of fat, 2 grams of protein and 6 grains of sugar. Hence in 9.6 one-hundred-calorie portions there would be 9.6 × 3--28.8 grams of fat, 9.6 × 2--19.2 grams of protein, and 9.6 × 6--57.6 grams of sugar, in a thirty-two-ounce mixture.
To determine the fuel value of the formula, these results must be multiplied by their physiological fuel factors, 9 and 4 and 4 respectively. Thus:
29 × 9 = 261 calories from fat 19 × 4 = 76 calories from protein 58 × 4 = 232 calories from sugar, or a total of ---- 569 calories for the entire mixture.
~Scheme for Adding Solids to Infants' Diet.~--
8 A.M.--Orange juice 1/2 ounce, or prune pulp or prune juice.
10 A.M.--Bottle, cereal (strained) and bread and butter or zwieback.
2 P.M.--Mutton, chicken, or veal soup cooked with cereal; small portion of baked potato, small portion of strained spinach or carrots; orange gelatin or cornstarch pudding.
