while the windows are open. The child may be placed 
in its crib or carriage before an open window, dressed 
as if for the street. After children are three months 
old they may be taken out, but the sunny part of the 
day should be chosen, between 10 a. m. and 3 p. m. in 
cold weather. At night the windows should be partly 
opened, but care should be taken that the infant does not 
become chilled. Be careful that sheet and blankets do 
not get over a baby's head. The clothes may be pinned 
to the side of the bed. 
Food and Water — Even little babies should be given 
water twice a day. The water should be boiled, cooled 
and kept covered. It is hardly possible for children or 
older persons to drink too much water. During hot 
weather a child needs more water than during cold 
weather. 
Mother’s milk is the only perfect food for an infant 
during the first nine or ten months. If it is necessary 
to give artificial food from a bottle, the greatest possible 
care must be taken. The milk used should be the best 
obtainable. To obtain clean milk it is necessary that 
everything that touches it be clean, sterilized when pos- 
sible, and that the cows, and men who handle the milk 
be healthy. In New York City all milk is classified 
according to its cleanliness and butter fat content. The 
cleanest and richest milk is called “certified milk" and 
is sold raw. The other milks are classified according to 
cleanliness. Grade A, B and C are all pasteurized. Only 
certified and Grade A should be used for infant feeding. 
You know that sterile means free from germs or bac- 
teria. Milk or water may be made comparatively sterile 
by boiling. Pasteurized milk is milk which has been 
heated to 155° Fahrenheit, kept at that temperature for 
thirty minutes and cooled quickly by placing the bottles 
in cold running water.
