My son of 1.8 years (from Pretoria in South Africa) has suffered from a cough for 6 months now. Is sounds wet one minute then dry the next. Also it is accommanied by runny nose (clear then green then clear again). I have had him on antibiotics, homeopath meds, clearing airway meds, taking him off diary, elevated his bed and pillow and rubbed Vicks on his chest and feet. Had him on various types of cough syrup etc. Honey at night. Steam him, humidity his room. Vacuum and change sheets weekly etc. Nothing seems to take it away. Taken him to ENT and doc says ears, nose and tonsils look good and chest sounds clear. His chest sounds phlegmy to me when he breathes at times though. He only coughs when he is active and at night when he sleeps. Wakes same times every night coughing. Various doctors say his too young for allergy tests.Please help. We loosing sleep and I am suffering from anxiety because I can t seem to solve this. Thanks.
