Growth & Development


All children engage in challenging behaviour from time to time which may or may not persist or be of concern. Behaviour is often a child’s way of communicating their wants and needs and in some cases may be their only method of communication. A child makes their needs known through observable actions. For example a child may indicate with gestures that they want a certain item or don’t want something they’ve been given, that they want more or less of your attention or that of a peer, that they don’t want to do a certain task or to go to a particular place, or that they don’t want to stop doing an activity that they are enjoying.

Behaviour is also a child’s way of telling their caregiver that he or she is in physical pain or discomfort, tired, hungry or ill.

Generally, a child demonstrates certain behaviour in the presence of certain people and not others, in specific situations or environments, and under some conditions while not in others.

When determining if a behaviour is of concern, it is important to keep in mind the context, the age and stage of the child, as well as to ascertain if there is an explanation for the behaviour.

When challenging behaviour happens many times each day, for long periods of time, or presents an immediate risk to the child or others it may require assessment and intervention from a professional.
