Key points

  • Challenging behaviour becomes a concern when it is frequent and unexpected and leads to trouble at home, at school and with peers.
  • Behavioural disorders generally fall into two categories: oppositional defiant disorder and conduct disorder.
  • Behavioural disorders can be associated with a family history of challenging behaviour, family stresses and a poor ability to manage emotions and activity levels.
  • See your child’s doctor if your child’s behaviour changes suddenly or if their behaviour is more challenging than expected for their developmental stage.
