When a child is struggling to breathe, it can be one of the scariest moments for any parent. Doctors say knowing what to look for — and when to get help — can make all the difference. Dr. Kelsey Grimes, an outpatient pediatrician with OSF HealthCare, says labored breathing, also called respiratory distress, can develop quickly and may signal a serious illness.

She says if your child is struggling to breathe during the day, try calling your pediatrician’s office or primary care provider for a same-day visit. If a child’s breathing seems severe, Dr. Grimes says don’t wait — call 9-1-1 or head to the emergency department. She says the most common cause of labored breathing in children is a viral infection that causes inflammation and mucus buildup.

Common viruses like RSV, rhinovirus, and influenza can make breathing harder for kids — but symptoms should start improving within a few days if treated properly. Parents can help at home by keeping their child hydrated, using nasal saline and suction, and controlling fevers with Tylenol or Motrin as directed by their pediatrician.

Other warning signs include drooling, blue coloring around the mouth, or head bobbing with each breath — all signs that require immediate medical attention.

Dr. Grimes says good hand hygiene and keeping kids from sharing food or drinks can help prevent these infections — but sometimes, exposure is unavoidable.

She says the best thing parents can do is stay alert for breathing changes and act quickly if something doesn’t seem right. Dr. Grimes adds that keeping up with your child’s recommended vaccinations also helps protect against respiratory illnesses.
