Definition
A foster-nurse is a woman who breastfeeds and cares for another woman's child, often a royal or noble infant, acting as a wet nurse and primary caregiver during the child's early years. This role was common in historical periods when mothers were unable or unwilling to breastfeed. She provides nourishment and nurturing, forming a close bond with the infant. Think of her as a surrogate mother in terms of early care. The role is now rare due to advances in infant formula.
