A wet nurse is a woman who nurses a baby that is not her own. A wet nurse may be employed if the birth mother of a baby is unable to breast-feed her infant for a variety of reasons. Some reasons may include the use of certain drugs (prescription or illegal), illness, or inoperative breasts. Wet nurses have also been required following multiple births where the mother has proved incapable of adequately nursing all of the children herself. (source: en.wikipedia.org)
