My daughter who is 2 and half year old has been coughing for almost 3 weeks now. The cough is not all over day. It is mostly in morning about 10 times and very few times in day. She was checks by 2 doctors and her chest has been clear however one of the doctors has diagnosed her with some allergy through food which we are not sure inspite of keep a vigil eye on her diet. The cough is not dry and with some mucus sometimes. The problem is now she has finished 2 bottles of cough syrup and i dont intend to give more syrup as it is yeilding no result.
