In the selection of a nurse, the physician should of course be consulted. She should be cheerful, amiable, orderly and cleanly; there should be no traces of hereditary or other disease; the skin should be sound, without eruption or trace of scrofulous disease; the mouth and teeth healthy; the breasts of moderate size and firm. It is desirable to choose a nurse whose child is about the age of the one she is about to suckle, although this is not always necessary. The milk should be thin, clear, of a bluish-white color, limpid and sweet. The food should be plain but nourishing, with the addition sometimes at dinner of a moderate allowance of ale or porter. She should exercise daily in the open air; her digestion should be good, and her bowels regular.
