Again and again they are disobedient, cheeky and aggressive. Their behaviour is quite out of the ordinary and seriously breaks the rules accepted in their family and community. It is much more than ordinary childish mischief or adolescent rebelliousness. This sort of behaviour will affect a child s development and interfere with their ability to lead a normal life. When behaviour is this much of a problem, it is called a conduct disorder .
Behavioural problems can occur in children of all ages.
Very often they start in early life. Toddlers and young children may refuse to do as they are asked by adults in spite of being asked many times. They are rude, swear and have tantrums. Hitting and kicking of other people is common. So is breaking or spoiling things which matter to others.
