Mom from WikiPedia:

A mother is a biological and/or social female parent of an offspring. Because of the complexity and differences of a mothers' social, cultural, and religious definitions and roles, it is challenging to define a mother to suit a universally accepted definition.

In the case of a mammal such as a human, the biological mother gestates a fertilized ovum. As a viable fertilised ovum or "embryo" ideally develops into a fetus. Gestation occurs in the mother's uterus from conception until (under ideal circumstances, barring illness or defect) the fetus is sufficiently developed to be born. The mother experiences labor and gives birth. Once the child is born, the mother produces milk via the lactation process. The mother's breast milk is the source of anti-bodies for the infant's immune system and commonly the sole source of nutrition for the first year or more of the child's life.
