Q

four maternal tasks that the woman accomplishes during pregnancy as she becomes a mother:

A
  1. Seeking safe passage for herself and her fetus. This involves both obtaining health care by a professional and adhering to important cultural practices.
  2. Securing acceptance of herself as a mother and for her fetus. Will her partner accept the infant? Does her partner or family have strong preferences for a child of a particular sex? Will the child be accepted even if he or she does not fit the ideal?
  3. Learning to give of self and to receive the care and concern of others. The woman will never again be the same carefree woman she was before her infant’s arrival. She depends on others in ways she has not experienced before.
  4. Committing herself to the child as she progresses through pregnancy. Much of the emotional work of pregnancy involves protecting and nurturing the fetus.
