The classic symptom of croup is a harsh, brassy cough that sounds like a seal's bark. This cough is often worse at night. And it usually occurs with hoarseness and loud, raspy breathing.
Other symptoms vary, depending on whether the illness is infectious croup or spasmodic croup.
Most children with infectious croup are mildly ill and do not develop significant breathing problems.
Among the few who do develop more severe forms of the illness, symptoms can include:
These symptoms often will pass if the child is carried into cool night air or taken into a steamy bathroom.
Symptoms from spasmodic croup usually improve within a few hours. However, it is common for the symptoms to reappear several nights in a row.
