Croup warning signs: when a child needs urgent care

Croup swelling can narrow the upper airway. A barking cough and hoarse voice may be uncomfortable but do not by themselves show how hard the child is working to breathe. Listen for stridor when the child is calm, not only during crying. Watch the chest and neck for skin pulling inward with each breath. Trouble swallowing, drooling, or a change in alertness can indicate that the child needs prompt assessment. A mild fever or runny nose may accompany croup, but breathing and responsiveness guide urgency.

Keep the child upright and calm, loosen tight clothing, and avoid smoke. Do not leave the child alone or force food and drink if breathing or swallowing is difficult. If the child can swallow comfortably, offer small sips. Note whether the noisy breathing happens at rest, whether the ribs pull in, and whether the child remains alert. Do not use hot steam or unprescribed medicine. A clinician may advise urgent treatment, including a nebuliser treatment in a suitable setting.

Call emergency services or go to emergency care for stridor at rest, severe chest or neck retractions, pauses in breathing, blue or grey lips, inability to speak or cry, drooling with an inability to swallow, or unusual sleepiness. Seek same-day medical advice if the cough is worsening, drinking is reduced, fever continues, or you are uncertain about the breathing sound. Do not wait for all warning signs to appear.

Ask which breathing sounds require emergency action, how to position the child, when to repeat any prescribed medicine, and what follow-up is needed. Share a timeline of cough, fever, drinking, sleep, and breathing changes.
