It sounds as if your son has croup. Keep his nose clear by using a saline nasal spray such as Sterimar two to three times a day. If he starts to cough again tonight take him into the bathroom for 10 to 15 minutes and turn on the hot shower in order to steam up the bathroom. Of course he should NOT be in the shower just in the bathroom while the shower is running and the place is all nice and steamed up.If he is still coughing tomorrow he should be seen by your doctor.
