The most typical symptom is a “seal-like” cough or a bark-sounding cough. The best at-home remedy is cold air, so wrap your baby up in blankets and open the window or go for a walk around the block. If that doesn’t help, call your pediatrician. There are prescription steroid medications that also are helpful for treating the symptoms. But because croup is caused by a virus, it will resolve on its own in a few days and won’t get better with antibiotics.
