Parental and sibling alliances
Family meal

Separation of illness from the child
Goal to have child eating independently and maintaining an
ideal, expected BMI at the 50thpercentile
Parents play an active role in helping to restore the child’s weight, then transition the control over eating back to the child and encourage normal adolescent development
