An 18-month-old wakes up at midnight with a harsh barking cough that sounds like a seal. Between coughs the child is calm and drinking water. What is this most likely?
Neck Sucking In With a Cough: Signs of Upper Airway Resistance
Why Coughing Causes Neck Pulling-In
- Coughing creates sudden bursts of high pressure inside the chest and airway — in young children, the windpipe cartilage is soft enough that these pressure swings can briefly narrow or collapse the airway.
- After each cough, the child must inhale quickly against an airway that may still be partially narrowed from swelling, mucus, or the cough itself — this extra effort pulls the soft skin at the throat inward.
- The most common cause of a barking cough with neck pulling-in is croup — a viral infection that causes swelling just below the voice box, narrowing the airway at its already smallest point.
- Croup most commonly affects children aged 6 months to 3 years and tends to worsen at night.
- Other causes include a foreign body in the airway, bacterial infections of the windpipe, and conditions where the airway cartilage is naturally floppy.
When to Worry
- A harsh seal-like barking cough paired with a high-pitched squeaking sound when breathing in — called stridor — is the hallmark pattern of upper airway narrowing and needs medical evaluation.
- Pulling that continues with every breath even when the child is calm and not coughing — not just during or right after a coughing fit — is more concerning.
- A child who is anxious, refusing to drink, drooling, or becoming very quiet between coughing episodes may be struggling and needs prompt evaluation.
- Any blue or gray color around the lips or fingernails means oxygen levels may be dropping — seek emergency care immediately.
- Record a short video on your phone if possible — symptoms often improve by the time you reach the office and the video helps the pediatrician see exactly what happened.
