What should I do about cough in my 2.5-month-old baby?

When your 2.5-month-old has a cough, the first step is to evaluate the type of cough and accompanying symptoms. At this age, since the immune system is still very weak, a cough could be from a simple cold or could signal something more serious.

Before you do anything, you must consult a pediatrician, but generally:

• Dry, barking cough (if hoarseness accompanies it) could indicate croup (laryngitis) and requires urgent evaluation.
• Wet/wheezy cough can indicate lower respiratory tract infection (bronchiolitis, pneumonia).
• Cough + fever: Fever 38°C or higher in a baby under 3 months (2.5 months) requires emergency doctor visit.
• Cough + difficulty breathing (rapid breathing, flaring nostrils, bluish lips) — call 112 or go to emergency immediately.

What can be done at home (after doctor approval):

• Keep the room humid (humidifier or sitting in a bathroom with steam for 10-15 minutes, not exposing baby directly to hot water).
• If nasal congestion: saline drops + nose aspirator for cleaning.
• Plenty of fluids (breast milk/formula at normal frequency) — don't give water.
• Keep baby upright (especially after feeding).

Definitely avoid:

• Over-the-counter cough syrup, herbal tea, honey (botulism risk under age 1), onion/pepper home remedies without prescription.
• Overheating and sweating baby.
• Suppressing cough with unprescribed medication.

Summary: In a 2.5-month-old with cough, check for accompanying fever, breathing difficulty, inability to feed, restlessness, or sleepiness. If any of these are present, go to emergency. Otherwise, make sure to have baby examined by a pediatrician today or by tomorrow at the latest — cough at 2.5 months doesn't go away on its own.
