I am a parent of a developementally disabled young addult with aggression issues, as well as an RN who has worked in Behavior health with Adults and teens for greater than 20 years. Restraining anyone usually invokes a negative response, flight or FIGHT, for example. Sometimes a person cannot be talked down but can be redirected, provided with a safe environment- and allowed to blow off their steam. This is not always the easiest option. Schools must be provided funding for training and options.. this is essential, so that teachers and caregivers can provide the safe care needed in difficult situations. Preventing the difficult situation is key and with out frequent training this is not possible.Adequate staffing is also paramount, and a dire need.  Children deserve this option of safe and loving environments, no matter their mental illness or disability.
