We all communicate through our behaviour whether we realise it or not. For example, an infant may cry when it is hungry or wet, just like an adult may yawn when he is bored at work. A child’s problematic behaviour is usually a sign that they are upset or that something is not right, and they are having trouble communicating that either because they don’t know what they feel, or they don’t have the right way to tell us. For example, a child might be screaming because they don’t want to do something, or they might feel unsafe or out of control; so they take inappropriate action over the things they can control (e.g. like kicking someone or being obsessive about a mobile phone).
