The document discusses the functions and roles of families. Some key functions of families are providing food, shelter, care, and protection for children. Factors like laws, education, technology, and divorce have changed traditional family structures and roles. Traditionally, husbands were breadwinners and decision-makers while wives cared for the home and children. Now roles are often shared or reversed, with responsibilities divided less rigidly between parents. Children develop male and female roles through both physical factors and the expectations and observations shaped by their environment and the adults around them.
