Hello doctor, Im from chennai. My son is 2.5 yrs old, height-87cm, weight-11.5kg. He is often getting cold continued by running nose, cough and also that sound from chest. This occurs aleast once in a month. Iam giving medicines prescribed by doctor like moxikind tab, ambrolin, omnacortil, chericoff, cefolac not all in a single time but in some combination prescribed by doctor. Is it ok like i can proceed with these medicine, if in future my son gets ill? What is the reason for frequent illness? and how can i avoid it? Will this create any seroius problem for my son in future? Is he healthy orelse give me a good diet chart for him.
