From the ninth to the twelfth month:
| Milk (top 16 oz.) | 35 ounces. |
| Milk-sugar | 2-1/2 ounces. |
| Lime-water | 6 ounces. |
| Water to make | 56 ounces. |
Five to six feedings in twenty-four hours; 7 to 9 ounces at each feeding.
It will be observed that 16 ounces of top-milk is used to make the various formulas from. This means that the mother will dip off, with a Chapin dipper, 16 ounces from the top of a bottle of milk which has stood for four or five hours to allow the cream to rise; she will then mix this and take from the mixture the number of ounces called for in the formula she is using according to the age of the child. The ordinary milk that is delivered in New York City may be assumed to have stood the four or five hours necessary. This may not be so, however, in the country, as it is frequently delivered there as soon as it is milked. In such cases the mother will permit it to stand in the ice box until the cream has risen.
When the mother is about to make the mixture called for in feeding from the third to the fifth month she will observe that 18 ounces of milk is called for. Now since she only uses 16 ounces of the top-milk from one bottle this will not be enough. She must therefore use 16 ounces from two bottles of milk; this she will mix together and from this mixture she will take the 18 ounces wanted. Whatever milk is left over may be used for ordinary table purposes.
EASY BOTTLE-FEEDING METHOD
The following formulas and instructions for bottle-feeding are taken from the Rules for the Care of Infants and Young Children which are used by Dr. Kerley at the out-patient department of the Babies' Hospital and give the simplest and easiest means of bottle-feeding:
Bottle-Feeding.—The bottle should be thoroughly cleansed with borax and hot water (one teaspoonful of borax to a pint of water) and boil before using. The nipple should be turned inside out, scrubbed with a brush, using hot borax water. The brush should be used for no other purpose. The bottle and nipple should rest in plain boiled water until wanted. Never use grocery milk. Use only bottled milk which is delivered every morning. From May 1st to October 1st the milk should be boiled five minutes immediately after receiving. Children of the same age vary greatly as to the strength and amount of food required. A mixture, when prepared, should be put in a covered glass fruit-jar and kept on the ice. For the average baby the following mixture will be found useful:
"For a child under six weeks of age: Nine ounces of milk, twenty-seven ounces of barley-water, four teaspoonfuls of granulated sugar. Feed from two to three ounces at two and one-quarter hour intervals, nine feedings in twenty-four hours.
"Sixth to the twelfth week: Twelve ounces milk, twenty-four ounces barley-water, five teaspoonfuls sugar. Feed from three to four ounces at each feeding.
