My 3 year old DS has a cough. He is probably coughing every 3 mins or so but it doesn't last long. He sounds very mucousy - last night he woke up crying and it sounded like the mucous was at the back of his throat. No temperature and eating fine. Looking at NHS website I'm not sure he needs a test? Sounds like the common cold and doesn't have the classic temperature. However, not sure whether to get test to be on the safe side. Can anyone help me decide what to do? Everyone else in household is fine (my DH and 1 year old DS)
