Münchausen Syndrome by Proxy

There is a mental illness named “Münchausen Syndrome by Proxy” where a caregiver deliberately induces physical or mental problems in those who are in their care. This is typically done to gain attention and sympathy for themselves. Approximately 1% of asthma cases in children are faked by their parents. The worst case where this was noticed was of Marybeth Tinning, who is suspected of have killed all 9 of her children in a span of 14 years.
