Responding to Aggressive Behaviours. It’s very upsetting to see your child kick, bite, throw toys, yell and scream, which are examples of aggressive behaviour. Early learning specialists recognize aggressive behaviour as a form of communication. Toddlers, preschoolers and even school-aged children are still learning to use words to express strong feelings. When they feel angry, frustrated, scared or sad, they often lash out physically because they don’t know what else to do. When a child behaves aggressively in our programs, our first step is to try to calm the child. Then, we try to understand what is going on.
