_Of what use are the proteids?_

They are needed for the growth of the cells of the body, such as those
of the blood, the various organs, and the muscles.

_Of what use are the salts?_

Particularly for the growth of bone.

_Of what use is the water?_

By means of the water the food is kept in a state of minute
subdivision or in solution, so that the delicate organs of a young
infant can digest it. It is also necessary to enable the body to get
rid of its waste.


NURSING

_Should all mothers attempt to nurse their children?_

As a rule they should do so, but there are many conditions when they
should not.

_What are the most important ones?_

If the mother has or has had tuberculosis or any other serious chronic
disease, or is herself in very delicate health, she should not try.
She is likely soon to fail in nourishing her child, and the attempt
may do herself much harm as well as injure the child.
