My baby's nasal discharge was clear at first, now it's thickened and turned yellow but there's no fever. Is this a sign of infection? Should I take him to the doctor?

A change in nasal discharge from clear to yellow/dark color is not by itself a sign of bacterial infection. This is a process that shows your immune system is working normally — as the body fights the infection, rising white blood cells and enzymes thicken the discharge. A yellow/dark color is also common in viral colds.
The absence of fever is a good sign. Your decision to see a doctor should be based not on the color of the discharge, but on accompanying symptoms:
- I recommend going to the doctor in these cases: discharge lasting more than 10 days, high fever (≥38°C), fussiness, poor feeding/drinking, swelling or redness around the eyes, especially one-sided green-yellow discharge.
- You can monitor at home in this case: only nasal discharge, general condition is good, appetite and sleep are close to normal.
As your baby grows, the consistency of nasal discharge naturally changes. If there are no other concerns, this color change is not cause for alarm.
