Cough in Children
Cough helps clear materials from the airways and prevent them from going to the lungs. The materials may be particles that have been inhaled or substances from the lungs and/or airways. Most commonly, material coughed up from the lungs and airways is sputum (also called phlegm—a mixture of mucus, debris, and cells ejected from the lungs). But sometimes a cough brings up blood. A cough that brings up either is considered productive. Older children (and adults) typically cough material out, but younger children usually swallow it. Some coughs do not bring anything up. They are considered dry or nonproductive. Cough is one of the most common reasons parents bring their children to a health care practitioner. (See also Cough in Adults .)
