Add water or other substances to cow’s milk to change it to agree with
the digestion of the infant. Malted foods when mixed with water are
deficient, and by adding milk or cream it becomes modified milk.
All mixtures should be cold when adding milk, and water sterilized when
used as a diluent.
_Note._—The natural food for the infant is human milk. The breast-fed
babies are healthier, more vigorous, and more resistant to disease.
