Child work covers the application of physical and mental contributions by children towards achieving a personal or communal goal. As a form of prosocial behavior, children's work is often a vital contribution towards community productivity and typically involves non-exploitative motivations for children's engagement in work activities. Activities can range from domestic household chores to participation in family and community endeavors. Inge Bolin notes that children's work can blur the boundaries between learning, play, and work in a form of productive interaction between children and adults. Such activities do not have to be mutually exclusive.
