9-month-old wakes up coughing at night: why?

My 9-month-old seems fine during the day but wakes up with coughing fits at night. Why does the cough get worse when he's lying down?

The most common reason night coughing gets worse is that when your baby lies down, the mucus from a runny nose drains down the back of his throat (postnasal drip). During the day when he's upright, the mucus drains forward or he swallows it without noticing. But lying flat, it pools and irritates his throat, triggering cough. Another reason can be that cold, dry air irritates his airway.
Things that might help:
- Clean his nose with saline drops and a nasal aspirator before bed.
- Slightly elevate his head — put a thin towel under the crib mattress at the head end to create a gentle slope (don't use a pillow; 9 months is still too young).
- Use a humidifier to add moisture to the air — this helps a lot.
- If a bad cough starts at night, pick him up and hold him upright, gently patting his back. This helps the drainage move and can ease the cough.
If the cough comes with fever, fast breathing, wheezing, or trouble eating, see your pediatrician.
