Most children with mild croup improve with calm supportive care. Croup can sound frightening because of the barking cough. The important thing is to watch breathing, keep the child calm, and seek urgent care if noisy breathing happens at rest.

What is it?

Croup is usually a viral illness affecting the upper airway. Swelling around the voice box and windpipe can cause a barking cough, hoarse voice, and noisy breathing called stridor.

Symptoms are often worse at night. Croup is common in young children, but babies under 6 months with croup-like symptoms should be assessed promptly.

Symptoms and signs

  • Barking cough, often described as harsh or seal-like.
  • Hoarse voice, sore throat, runny nose, fever, or other cold symptoms.
  • Noisy breathing, especially when breathing in.
  • Symptoms that become more noticeable at night or when the child cries.
  • Some children have only cough, while others need medical review for breathing difficulty.

Causes and spread

Croup is usually caused by common respiratory viruses. It spreads through coughs, sneezes, close contact, and contaminated hands or surfaces.

  • Wash hands often and teach children to cover coughs.
  • Avoid sharing cups, towels, and water bottles during illness.
  • Keep the child away from smoke, incense smoke, mosquito coil smoke, and strong fumes.

Home management

  • Keep the child calm. Crying can worsen noisy breathing.
  • Sit the child upright and offer small amounts of fluids often.
  • Let the child rest in a comfortable position.
  • Use fever or pain medicines only as advised for your child. This page does not give exact medicine amounts.
  • A doctor may prescribe medicine for croup when needed. Follow the doctor plan and return if breathing worsens.

What to avoid

  • Do not force examination of the throat at home. This can upset the child and worsen breathing effort.
  • Do not use steam inhalation as a recommended treatment. Hot water and steam can cause burns and may not help.
  • Avoid cough syrups unless a doctor has advised them for your child.
  • Do not delay urgent care if there is noisy breathing at rest or the child looks exhausted.

School and daycare guidance

Keep your child home while feverish, very tired, or struggling with cough or breathing. They can usually return when comfortable, fever-free, and able to participate, following local school or daycare policy.

Important facts

  • Croup often sounds worse at night and may fluctuate.
  • Keeping the child calm can reduce noisy breathing.
  • Steam is not recommended as a treatment because of burn risk and uncertain benefit.
  • Stridor at rest is a warning sign and needs urgent assessment.

Red flags / when to seek urgent care

Seek urgent medical care if your child has croup symptoms with any of these signs:
  • Stridor or noisy breathing while resting.
  • Breathing difficulty, chest or neck indrawing, or rapidly worsening symptoms.
  • Blue lips, pale or grey colour, or child looks very unwell.
  • Drooling, unable to swallow, or refusing fluids because swallowing is difficult.
  • Very drowsy, confused, exhausted, or agitated with breathing difficulty.
  • Poor fluid intake, dehydration, or very little urine.
  • Age under 6 months with croup-like symptoms.
  • You are worried or feel something is seriously wrong.
