I would inquire particularly into the state of her health; whether she be of a healthy family, or a consumptive habit, or if she or any of her family have labored under “king’s evil;” ascertaining if there be any seams or swellings about her neck; any eruptions or blotches upon her skin; if she has a plentiful breast of milk, and if it be of good quality (which may readily be ascertained by milking a little into a glass. “It should be thin, and of a bluish-white color, sweet to the taste, and when allowed to stand should throw up a considerable quantity of cream.”—_Maunsell and Evertson on the Diseases of Children._) If she has good nipples, sufficiently long for the baby to hold; that they be not sore; and if her own child be of the same or nearly of the same age as the one you wish her to nurse. Ascertain whether she menstruates during suckling; if she does, the milk is not so good and nourishing, and you had better decline taking her. Sir Charles Locock considers that a woman who menstruates during lactation is objectionable as a wet-nurse, and “that as a mother with her first child is more liable to that objection, that a second or a third child’s mother is more eligible than a first.”—_Letter to the Author._ Assure yourself that her own babe is strong and healthy, and that he is free from a sore mouth and from a “breaking-out” of the skin. Indeed, if it be possible to procure such a wet-nurse, she ought to be from the country, of ruddy complexion, of clear skin, and of between twenty and five-and-twenty years of age, as the milk will then be fresh, pure, and nourishing. I consider it to be of great importance that the infant of the wet-nurse should be, as nearly as possible, of the same age as your own, as the milk varies in quality according to the age of the child. For instance, during the commencement of suckling, the milk is thick and creamy, similar to the biestings of a cow, which, if given to a babe of a few months old, would cause derangement of the stomach and bowels. After the first few days, the appearance of the milk changes; it becomes of a bluish-white color, and contains less nourishment. The milk gradually becomes more and more nourishing as the infant becomes older and requires more support. In selecting a wet-nurse for a very small and feeble babe, you must carefully ascertain that the nipples of the wet-nurse are good and soft, and yet not very large: if they be very large, the child’s mouth being very small, he may not be able to hold them. You must note, too, whether the milk flows readily from the nipple into the child’s mouth; if it does not, he may not have strength to draw it, and he would soon die of starvation. The only way of ascertaining whether the infant actually draws the milk from the nipple, can be done by examining the mouth of the child _immediately_ after his taking the breast, and seeing for yourself whether there be actually milk in his mouth.
