Parentification

Parentification is the process of role reversal whereby a child is obliged to act as parent to their own parent. In extreme cases, the child is used to fill the void of the alienating parent's emotional life.

Two distinct modes of parentification have been identified technically: instrumental parentification and emotional parentification. Instrumental parentification involves the child completing physical tasks for the family, such as looking after a sick relative, paying bills, or providing assistance to younger siblings that would normally be provided by a parent. Emotional parentification occurs when a child or adolescent must take on the role of a confidant or mediator for (or between) parents and/or family members.
