How do I know if my child has croup?
If you're not sure if your child has croup, your doctor can diagnose it. The most common symptoms of croup are fever, hoarseness of the voice and a barking, hacking cough. Croup symptoms tend to affect children 1 to 3 years old more severely and may worsen at night. Call your doctor if you notice a high-pitched noise (called stridor) when your child breathes in or if your child is having problems breathing.
