Croup, which is marked by a harsh, repetitive cough similar to the noise of a seal barking, can be scary for children and their parents.
The barking cough of croup is the result of inflammation around the vocal cords (larynx) and windpipe (trachea). When the cough reflex forces air through this narrowed passage, the vocal cords vibrate with a barking noise. Because children have small airways to begin with, those younger than age 5 are most susceptible to having more-marked symptoms with croup.
Croup usually isn't serious. Most cases of croup can be treated at home. Sometimes, your child will need prescription medication.
