Croup (Barking Cough)

Croup is viral infection causing swelling around voice box and windpipe. Symptoms: Distinctive barking cough (sounds like seal), hoarse voice, stridor (high-pitched squeaking when breathing in), trouble breathing (worse at night).

Most common in fall/winter. Typically lasts 3-7 days. Starts with cold symptoms, then barking cough develops on day 2-3. Worse at night. Scary but usually mild.

Caused by parainfluenza virus. Most common in babies 6 months to 3 years.

What to Do

  • Stay calm - your anxiety makes baby more anxious (which worsens breathing)
  • Hold baby upright - sitting up helps breathing
  • Try cool mist: Take baby outside in cool night air for 10-15 minutes
  • Or steamy bathroom: Run hot shower and sit with baby in steamy room for 10-15 minutes
  • Use cool-mist humidifier in baby's room while sleeping
  • Offer fluids frequently to prevent dehydration
  • Give acetaminophen or ibuprofen for fever/discomfort
  • Doctor may prescribe: Steroid (dexamethasone) to reduce swelling - very effective
  • DO NOT give cough medicine - doesn't help croup and can be dangerous
  • Watch breathing closely - count breaths per minute (normal: 30-60 for babies)
  • Croup is contagious - keep home from daycare until fever-free for 24 hours
