(HealthDay News) -- Croup tends to occur between 3 months and 5 years of age, the American Academy of Pediatrics says.
Most common in autumn and winter, it causes swelling of the voice box and windpipe. This leads to a bark-like cough.
Most instances of croup resolve on their own, but occasionally it can lead to complications that require a visit to the ER.
The academy suggests calling a doctor if your child has these symptoms:
