Eating and mealtime problems are common in childhood. They are often stressful not only to the child, but to the entire family. In this case report we describe a multidimensional approach to the assessment and treatment of food aversion in a four year old boy. The integration of psychodynamic, systemic and behavioural concepts in the assessment and treatment is described. In addition we report on preliminary findings from the Children's Eating Behaviour Inventory, a new instrument under development, intended to assess eating and mealtime problems in children.
