My son Aadhavan Awasthi who has just turned 2 years and 2 months old. He had cough for some time and then we took him to the local hospital and gave him some antibiotic medicine. Even after that he did not get much relief, then I took him to a Private child specialist Hospital from where he was given same medicines but in increased doses. He did some blood tests in which some infection was found, so after that medicine he got relief but now he is having some cough, so what should I do?
