Explanation:

Formerly it was common for women who had school-age children to quit their jobs and stay home alone to care for their children. However, as the years progressed and the need for women to become economically independent, this behavior has been steadily decreasing and today, most women with school-age children are part of the workforce. While working and caring for children is an arduous task, the women of this century have managed it with mastery. However, it is important for the parents of the children to take responsibility and to help with childcare.
