What should you know about croup when to worry?

Croup causes swelling in the upper airway, often after cold-like symptoms. A barking cough and hoarseness may be mild at first. Crying can make the sound and effort worse, so watch what happens after your child settles. The most useful clues are breathing while resting, chest movement, skin colour, alertness, and ability to swallow. Fever may be present, but its absence does not determine how serious breathing symptoms are.

Hold your child upright, speak softly, and keep the surroundings calm. Offer frequent small sips only if swallowing is easy. Do not use hot steam or put anything into the throat. Note whether the noisy sound occurs only during crying or also when calm, and remember the time symptoms began. A healthcare professional can decide whether medicine, observation, or nebuliser treatment is appropriate.

Call emergency services immediately for blue or grey lips, pauses in breathing, severe chest pulling, inability to speak or cry, drooling with trouble swallowing, or marked drowsiness. Seek urgent assessment when a harsh breathing sound remains while your child is calm, breathing is fast or visibly difficult, or drinking is falling. Contact a clinician promptly if symptoms are getting worse or repeatedly disturbing sleep, even if your child seems brighter between episodes.

Ask which exact changes in breathing should trigger emergency care, whether a review is needed after an episode, and what medicine to keep available if croup returns. Share any recording of the sound if it has stopped before the appointment.
