title: Aggression during early years - infancy and preschool.
abstract: BACKGROUND
  This review explores the meaning and origins of aggression in early years. Eight pathways to aggression with origins in early childhood are suggested. These include: the contribution of individual factors; the effects of disturbed family dynamics; parental characteristics and parenting practices; the impact of exposure to violence and the influence of attachment relationships. Other influences such as: aggression relating to psychiatric/medical syndromes; the influence of neurodevelopment pathways and psychodynamic explanations, such as aggressive behavior in relation to mothers' reflective capacity are also discussed.
  
  
  CONCLUSIONS
  While several routes to aggression have been proposed, no single factor is sufficient to explain the development of aggressive behavior. Longitudinal studies are sorely needed to observe aggressive behavior in children and to monitor their developmental trajectories.
