Suggest Treatment For Cold And Cough In A Child

Hi My Daughter is 3 years 8 months old. We reside in Bangalore. We see that during summer she is doing well and if we visit Vijayawada which is comparatively hot weather she does well during all seasons. During winter she gets cold very easily and she gets a lot of flum and from the nose also she gets flum (Green Mucus) During this time when we visit doctors they say she has mild infection and she would get out of it once she grows big. They also said she is having Wheezing problem. (Infection in the throat) This is repeating during the winter season again now. Now the summer has started and we felt she is fine but still she is having cold and she is still suffering. We gave her some syrups like Bricanal and Aitrax to get over this, she is fine for few days and again statrs with cold. And she would get fever after she gets the cold and the cough, she wouldn t eat anything. Please suggest some remedy for this.
