The word ‘control’ is worth setting aside. The goal is not to control the person but to reduce distress and keep them safe. This works best through calm communication, predictable routines, and a safe environment rather than force or restriction. When behaviour is difficult, looking for the cause — pain, fear, confusion, an unmet need — is usually more effective than trying to stop the behaviour directly. Short sentences, a gentle tone, and redirecting attention to something familiar can help. If behaviour becomes unsafe and cannot be managed at home, a professional assessment may be needed.
