A. Hello! Your child is having very slow weight gain. Better to check with your consulting paediatrician for any kind of deficiency issues in this matter. Give me a child, a balanced, healthy diet that includes seasonal fruits and vegetables, green, leafy vegetables, nuts, dry fruits and dairy. If your family is non-vegetarian, even that should be included in the daily diet.
