what is it when a parent pretends to have a disease to their kid?
Fabricated or induced illness. Fabricated or induced illness (FII) is a rare form of child abuse. It occurs when a parent or carer, usually the child's biological mother, exaggerates or deliberately causes symptoms of illness in the child. FII is also known as 'Munchausen's syndrome by proxy' (not to be confused with Munchausen's syndrome, where a person pretends to be ill or causes illness or injury to themselves).
