A common childhood illness with a harsh, barking cough from a swollen airway — usually mild, but watch the breathing closely.
📝 Summary
In short: A common childhood illness with a harsh, barking cough from a swollen airway — usually mild, but watch the breathing closely.
Common causes: A cold-type **virus** that swells the voice box and windpipe (the most common cause); Sometimes a bacterial infection following a cold; A child's naturally **small, narrow airway**, which swells easily.
First thing to try: Stay calm and comfort your child — crying tightens the airway, so a quiet, reassuring lap helps the breathing settle.
See a doctor if: Your child **struggles to breathe**, or you hear harsh, noisy breathing even at rest
🌿 Overview
Croup comes from a virus that swells a young child's voice box and windpipe, giving a barking, seal-like cough. Most cases are mild and ease with calm, moist or cool air, and warm fluids. Because little airways are small, watch the breathing carefully and get emergency help if your child struggles to breathe.
Croup is a common childhood illness where a cold-type virus makes the voice box and windpipe swell, narrowing a young child's already-small airway. The telltale sign is a harsh, barking cough that sounds a bit like a seal, often with a raspy, squeaky noise when the child breathes in. It mostly affects little ones from about three months to three years old, and it tends to be worse at night. Most croup is mild and passes in a few days with simple comfort care. Calm, moist air (or a few minutes of cool night air) often eases the cough, and keeping the child relaxed truly matters — crying and panic tighten the airway and make the breathing harder, while a quiet, reassuring lap helps it settle. Even so, croup deserves close watching. Because a child's airway is so small, swelling can sometimes make breathing genuinely difficult. If your child is struggling to breathe, makes a harsh noise even while resting, looks blue or gray around the lips, or is drooling and cannot swallow, treat it as an emergency and get help right away.

✅ What to do
Gentle, practical steps you can take at home — start at the top.
- Stay calm and comfort your child — crying tightens the airway, so a quiet, reassuring lap helps the breathing settle.
- Moisten the air: run a cool-mist humidifier, or sit together in a steamy bathroom for a few minutes and let your child breathe the moist air (a gentle steam inhalationBreathing in warm, moist air to loosen mucus and soothe airways. How to make a steam inhalation →).
- Or step outside: a few minutes of cool night air often calms the barking cough.
- Offer frequent small sips of warm (not hot) water or weak, warm broth to keep the throat moist and loosen mucus.
- Prop your child up a little rather than lying flat, and let them rest.
- A warm compressA cloth soaked in warm or cold liquid, held on the skin. How to make a compress → on the chest can bring comfort once the worst of a spell has passed.
- A little eucalyptus in a room vaporizer may help an older child breathe easier — never put essential oils on a baby's skin or in their mouth.
- Skip cough and cold medicines — they don't help croup and can thicken the mucus.
- For a night-time barking spell, try this in order: hold your child calmly, breathe moist bathroom steam together for a few minutes, then step into cool outdoor air.
