Many Singaporean parents are guilty of comparing their kids with others, especially with regards tor results in school. While parents hope this would spur their children to achieve more, constant comparison usually results in the opposite. Being compared to their better-performing peers makes children feel angry and incompetent.
Instead, try to appreciate the child more. Praise him for his efforts and offer regular encouragement. These are signals to the child that he is doing something right and would result in a continuation of good behaviour.
