Hello there! thank you for asking. i read your query and i want to reassure you that if the cough is not associated with sputum or bad chest or fever then all you need to do is to treat the cough symptomatically. use some cough suppressants in guise of some anti histamine syrups, some bronchodilators like salbutamols and some Prokinetic syrups to avoid vomiting like Metoclopromide. I am sure symptoms will resolve but if the problem persisted for more than three days i would recommend to see the nearby pediatrician to be on the safer road and sort out thew cause for the resistant cough. Hope i was of some help regards Dr S Khan
