~Feeding Premature Infants.~--The method of feeding a premature infant
differs from that employed in feeding an infant born at term: (a)
because its development has not progressed so far; (b) because its
digestive apparatus being more or less immature, food handled with
ease by an older baby will be totally unfit for the premature one,
both as to quality and quantity.

~Wet Nurse.~--The advisability of procuring a wet nurse when the
mother is unable to nurse the infant, (a) on account of the more
digestible character of the food constituents, especially the
proteins, in mother's milk over those of cow's milk; (b) on account of
the resistance furnished by the natural food which has been proved to
be very much greater than that furnished by any other food, no matter
how carefully the modification of the milk is made.

~Premature Infants.~--Their caloric needs are greater than in
full-term babies, hence their food must be adjusted to meet these
needs.

In fact the nurse must have an understanding of the behavior of foods
in the metabolism of infancy and the laws which govern their use in
the organism of the child.

PROBLEMS

(a) Write a formula for a two months' old infant weighing twelve
pounds, which contains 3% fat, 2% protein, and 6% sugar.

(b) Change this formula so that it will contain 3% fat, 1.5% protein,
and 6% sugar.

(c) Write a formula for an eight months' old baby, using whole milk
instead of cream and skimmed milk.

(d) Write a formula for a premature baby containing 1% fat, 4% sugar,
and 0.25% protein (allowing 30 calories per pound of body weight).
