Any ideas on how to stop coughing spells? My son is having about one or two times a day where he coughs and coughs and coughs.He finally stops when he gets too tired I think. He just goes to sleep. I cannot tell if it is his throat that is itching or what. I keep trying just about all the "medicines" (which I do not really like doing) but they do not seem to help. I spray throat spray, give inhaler, cough syrups etc.. nothing helps.. he keeps coughing... any natural remedies that might help?
