Parent

A parent is a father or mother; one who sires or gives birth to and/or nurtures and raises an offspring. The different role of parents varies throughout the tree of life, and is especially complex in human culture.
Mother
A mother is the biological or social female parent of a child or offspring. The maternal bond describes the feelings the mother has for her (or another's) child. In the case of a mammal such as a human, the mother gestates her child (called first an embryo, then a fetus) in the uterus from conception until the fetus is sufficiently well-developed to be born. The mother then goes into labour and gives birth. Once the child is born, the mother produces milk to feed the child.
