My 4 yr daughter catches cold frequently (every month) but earlier it use to go itself without much medicines. But from the last 8 months it has become a big problem, without antibiotics it doesn't subsidises and takes 10 days. It stats with a very little cold and running nose but after a day or two it really become a big issue. Twice she has reported ear infection also. Please suggest me what to do? we recently sifted to vizag, is this because of change of place?
