is very poor so that the infant regularly leaves some of its
food.

_When should the interval between the feedings be shortened?_

This is done much too frequently; it is rarely advisable to feed any
infant, except one seriously ill, oftener than the time put down in
the schedule.

REGULARITY IN FEEDING

_How can a baby be taught to be regular in its habits of eating and
sleeping?_

By always feeding at regular intervals and putting to sleep at exactly
the same time every day and evening.

_When should regular training be begun?_

During the first week of life.

_Should a baby be wakened to be nursed or fed if sleeping quietly?_

Yes, for a few days. This will not be required long, for with regular
feeding an infant soon wakes regularly for its meal, almost upon the
minute.

_Should regularity in feeding be kept up at night as well as during
the day?_

Only up to nine or ten o'clock; after that time a baby should be
allowed to sleep as long as it will.

_At what age may a well baby go without food from 10 P.M. to 6 or 7
A.M.?_

Usually at four months, and always at five or six months. Night
feeding is one of the most frequent causes of wakefulness and
disturbed sleep.

STERILIZED MILK

_What is meant by sterilizing milk?_

Heating milk for the purpose of destroying germs.

_Does all cows milk contain germs?_

Yes; even when handled most carefully, milk contains many germs; but
when carelessly handled, and in summer, the number is enormous. While
most of these are harmless or cause only the souring of milk, others
are occasionally present which may produce serious diseases such as
typhoid fever, diphtheria scarlet fever, cholera, tuberculosis, and
many forms of diarrhoea.

_Under what circumstances is it necessary to sterilize milk?_

1. In warm weather when it cannot be obtained fresh; hence always in
cities and towns during the summer.

2. When one cannot be certain that the cows are healthy, or that the
milk has been carefully handled.

3. When the milk is to be kept for any considerable time (i.e., over
twenty-four hours), especially if no ice can be had.

4. During epidemics of typhoid fever, scarlet fever, diphtheria, or
any form of diarrhoeal disease.

_What are the two methods of heating milk?_

The first is known as _sterilizing_, in which the milk is heated to
212 deg. F. for one hour or one hour and a half; the second is known as
_pasteurizing_, in which the milk is hea
