Question:
My 8-month-old baby is coughing heavily. They have been taking medication for a head cold. After two 3-day courses of symptom relief medication, thick yellow nasal discharge started, so antibiotics were added for 3 days. Then, an early-stage middle ear infection (otitis media) was found in one ear, so the antibiotic course was extended.

However, starting this afternoon, my baby has been struggling with a severe cough during naps and nighttime sleep. I am currently keeping them in an elevated, upright position to help them sleep. Should we take the baby in to get a chest X-ray?
Answer:
It is completely understandable to be worried when your 8-month-old baby is struggling with a worsening cough, especially after dealing with a cold and an ear infection.
Here is what you need to know regarding immediate care and whether an X-ray is necessary.
When to Seek Immediate Emergency Care
If you notice any of the following signs, take your baby to an urgent care clinic or emergency room immediately:
Skin pulling in under the rib cage or neck when breathing (retractions)
Bluish tint to the lips or fingernails (cyanosis)
Continuous wheezing or a grunting sound when breathing
Breathing too fast to drink from a bottle or eat
No wet diaper for over 8 hours
Extreme lethargy, floppiness, or weak response when woken up
Home Care Management
Keep the upper body elevated: You are already doing this, and it is a great strategy to help reduce coughing caused by postnasal drip.
Nasal care: Use a saline nasal spray followed by a nasal aspirator (suction bulb) right before sleep and upon waking up.
Humidify the air: Keep indoor humidity between 40-60% using a cool-mist humidifier.
Hydration: Offer fluids frequently. Give breastmilk or formula in small, frequent amounts, and keep solid foods on the watery side.
Room environment: Maintain a comfortable room temperature (around 68-72°F or 20-22°C) and dress the baby in lightweight clothing.
Do You Need a Chest X-ray?
Your pediatrician will determine if an X-ray is necessary after listening to your baby's lungs with a stethoscope. Rather than requesting an X-ray right away, it is best to ask your doctor questions such as:
"Since the cough has worsened, is there a possibility of pneumonia?"
"Based on what you hear through the stethoscope, do you think a chest X-ray is needed?"
When to Follow Up with Your Doctor
Since your pediatrician is already actively managing the ear infection, continue with the home care steps above and monitor your baby closely. You should contact or visit your pediatrician if:
The cough gets significantly worse or completely prevents your baby from sleeping through the night.
There is no overall improvement after 48 to 72 hours of taking the antibiotics.
A fever returns, breathing becomes rapid, or their food intake drops to less than half of their normal amount.
