Biological mother
Biological motherhood for humans, as in other mammals, occurs when a pregnant female gestates a fertilized ovum (the "egg"). A female can become pregnant through sexual intercourse after she has begun to ovulate. In well-nourished girls, menarche (the first menstrual period)  usually takes place around the age of 12 or 13.Typically, a fetus develops from the viable zygote, resulting in an embryo. Gestation occurs in the womans uterus until the fetus (assuming it is carried to term) is sufficiently developed to be born. In humans, gestation is often around 9 months in duration, after which the woman experiences labor and gives birth. This is not always the case, however, as some babies are born prematurely, late, or in the case of stillbirth, do not survive gestation. Usually, once the baby is born, the mother produces milk via the lactation process. The mothers breast milk is the source of antibodies for the infants immune system, and commonly the sole source of nutrition for newborns before they are able to eat and digest other foods; older infants and toddlers may continue to be breastfed, in combination with other foods, which should be introduced from approximately six months of age.Childlessness is the state of not having children. Childlessness may have personal, social or political significance.
Historically, the role of women was confined to some extent to being a mother and wife, with women being expected to dedicate most of their energy to these roles, and to spend most of their time taking care of the home. In many cultures, women received significant help in performing these tasks from older female relatives, such as mothers in law or their own mothers. Regarding women in the workforce, mothers are said to often follow a "mommy track" rather than being entirely "career women". Mothers may be stay at home mothers or working mothers. In recent decades there has been an increase in stay at home fathers too. Social views on these arrangements vary significantly by culture: in Europe for instance, in German-speaking countries there is a strong tradition of mothers exiting the workforce and being homemakers. Mothers have historically fulfilled the primary role in raising children, but since the late 20th century, the role of the father in child care has been given greater prominence and social acceptance in some Western countries. The 20th century also saw more and more women entering paid work. Mothers rights within the workforce include maternity leave and parental leave. The social role and experience of motherhood varies greatly depending upon location. Mothers are more likely than fathers to encourage assimilative and communion-enhancing patterns in their children. Mothers are more likely than fathers to acknowledge their childrens contributions in conversation.
