_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.
