Who will take care of the children of the average American family?

Traditionally, American families are housewives who take care of their children at home after their mothers give birth, but now more and more American families continue to work after their mothers take maternity leave. Parents take turns to take care of their children, send them to the community nursery during working hours and pick them up after work. In addition, it is popular for Asian families in American families to ask their elders to take care of their children, but other ethnic groups do not have this habit.
