Croup can be really scary to hear as a parent—the cough often sounds like a “barking seal,” and symptoms tend to get worse at night. It’s most commonly caused by viruses like parainfluenza, RSV, influenza, adenovirus, and even COVID-19, which lead to swelling in the upper airway.
Parents might notice a hoarse voice or a high-pitched sound when the child breathes in (stridor). While it can feel alarming, the good news is that most cases are mild and get better with time and simple supportive care, such as rest, fluids, and comfort measures like a cool mist humidifier or sitting with the child in a steamy bathroom.
When needed, we often use a dose of an oral steroid to help calm the airway swelling. If a child is having more trouble breathing, they may need to be seen in the ER, where treatments like racemic epinephrine can help quickly. After that treatment though, a period of observation iin the ER s important to make sure symptoms don’t come back as the medication wears off.
We know how stressful this can feel—especially in the middle of the night—but with the right care and support, most children recover quickly and do very well.
