Croup often shows up at night & that sudden, barking cough can be scary to hear! 😮💨 Most of the time, croup is caused by a virus and improves after several days with comfort, cool mist, and fluids.
Sometimes, the virus causes more swelling in the airway, which makes it difficult for your child to breathe, and treatment is needed.
If your child has noisy breathing or trouble catching their breath, call your pediatrician or seek care right away.
