My daughter is 4 year 7 month old and when winter is come she is suffering from cough and cold . Last year her doctor said she have asthma and prescribed inhaler but other than cough and cold she doesn’t have any problem like breathing problem etc . We stop inhaler about 3-4 months continue and she have no issues at that period but again winter is come and she have cough and cold. I am giving her ginger juice at night for cough and it is under control but sometimes she is coughing and we don’t understand what to do?
