A. hi well ,there is difference between to have low weight and to look thin. so , first ensure that a child is having enough (19 to 22kg) weight or not. if weight is low ,give food like nuts , dry fruits, paneer ,curd ,ghee ,milk , etc prepare dry fruits powder from almonds, cashew, pista, walnuts etc and add it while serving full cream milk to child.
