Dear Doctor, We recently shifted to bangalore from vellore few days back. My son is 5+ yrs old, we put him in new school. He is always down with breathing problem either wheeze or blocked nose, specifically during night he can't sleep. he used to get wheeze once in a while when v r in native. But after shifting to bangalore he is getting often. He is active but not like before. I m worried whether he ll adapt with this cold climate or what shall I do?
