6 A.M. At two years a child can easily go from 6 P.M. to 6 A.M.
without feeding.

_How should a baby be put to sleep?_

The room should be darkened and quiet, the child's hunger satisfied,
and the child made generally comfortable and laid in its crib while
awake.

_Is rocking necessary?_

By no means. It is a habit easily acquired, but hard to break, and a
very useless and sometimes injurious one. The same may be said of
sucking a rubber nipple, or "pacifier," and all other devices for
putting children to sleep.

_What are the principal causes of disturbed sleep?_

As quiet peaceful sleep is a sign of perfect health, disorders of
sleep may be produced by almost anything which is wrong with the
child.

1. Habitual disturbance of sleep in infants is most frequently
associated with the food or feeding. It may be from the discomfort of
chronic indigestion due to improper food. In bottle-fed infants it is
often the result of overfeeding; in those who are nursed it is often
due to hunger. A common cause is frequent night feeding; an infant who
is fed three or four times during the night is almost invariably a bad
sleeper.
