My baby is fine during the day but starts coughing dryly when he lies down at night. Why does his cough get worse at night?

The most common reason for a dry cough that increases when lying down is drainage of nasal secretions to the back of the throat (postnasal drip). When upright during the day, this drainage goes unnoticed, but when lying flat at night, gravity pulls the secretions down and triggers coughing.
Other possible causes:
- Dry air in the room (especially in winter with heated homes) irritates the throat.
- Reflux: stomach contents backing up when lying down can also cause night coughing.
- Asthma or bronchitis: usually accompanied by daytime cough but worse at night.
What you can do:
- Slightly elevate your baby's head in bed (by putting a towel under the mattress, never use a pillow — risk of sudden infant death).
- Use a humidifier in the room (clean humidifier or damp towel over a radiator).
- Offer plenty of fluids (water if 6+ months, breast milk or formula).
- Nasal saline rinse before bedtime can help.
When to see a doctor:
- Cough lasts more than 2 weeks.
- Fever, wheezing, or shortness of breath accompanies the cough.
- Baby refuses to eat or has difficulty breathing (rapid breathing, flaring nostrils, rib retractions) — go to emergency care.
