What should I give 2.6 year old which Supplements/ vitamins Indian style? He always falls sick, catch cold every month twice.. I yet not started anything.. What should help him in immune, height and in brain development as compared to his age group he is below line in this all?

Hey, Personally, I do not believe in giving supplements to kids unless they have real developmental issues, in which case you should seek your doctors advice than randomly giving him supplements that you think or your friend thinks will work best. I understand your concern for your child, and you are raising this question because you are worried about him falling sick often and not matching the ideal weight and height according to his age, but I think for this you should check with his paediatrician and do whatever he advices.
