What is the definition of Muchausen by Proxy?

Munchausen by proxy is a form of child abuse, and a type of mental illness that requires treatment. An individual, generally either the parent or the main caretaker, either exaggerates or even fabricates illness symptoms in a child, in order to gain attention and sympathy for themselves. The caretaker may even go so far as to cause symptoms via poisoning, overdosing with medication, or suffocating the child. In as many as 85% of cases, the mother is the individual responsible for fabricating the symptoms.
