The term "wet nurse" refers to a woman who breastfeeds and cares for another woman's child. The antonyms for wet nurse are "biological mother" and "adoptive mother."
A biological mother is the woman who gives birth to the child and is responsible for their upbringing and welfare. An adoptive mother is a woman who has legally adopted a child and assumes the role of a parent.
While wet nursing was a common practice in the past, it is not as prevalent today. Many women choose to feed their infants with formula or express breast milk via a breast pump. However, in some cases where a mother is unable to breastfeed, a wet nurse may be enlisted to provide nourishment and care for the child.
