If your 8-month-old baby has a cough and runny nose, you can choose a treatment depending on the cause and severity of the illness. If the upper respiratory tract infection is caused by a virus and the symptoms of coughing and runny nose are mild, medication is usually not needed, and the child can be encouraged to drink plenty of boiled water and fresh fruit juices to alleviate the symptoms of coughing and runny nose, and at the same time, the room in which the child lives should be kept at a fresh air level and a temperature of about 20 degrees Celsius. If the cough and runny nose are more serious, you can take cefixime granules for anti-inflammatory treatment, as well as expectorant cough granules and aminophenol xanthamin granules for symptomatic treatment.
