Your baby's mucus is likely yellow because it has been sitting in their nose or sinuses for a while.
Understanding Yellow Mucus in Babies
Yellow mucus in babies can be alarming for parents, but it's often a normal part of a cold's progression. Here's a more detailed look at why it happens:
- Stagnant Mucus: According to research, snot can turn yellow when it has been sitting in your baby's nose or sinuses for a while.
- Cold Progression: Snot can also turn yellow as a cold progresses into the thick snot phase. The change in color and consistency happens due to the accumulation of cells and proteins in the mucus.
Is Yellow Mucus Always a Sign of Infection?
Generally, yellow mucus alone does not mean that your baby currently has a sinus infection. However, if the yellow mucus is accompanied by other symptoms, further evaluation may be needed.
When to Consult a Doctor
Consult a doctor if your baby experiences any of the following symptoms in addition to the yellow mucus:
- Fever
- Difficulty breathing
- Persistent cough
- Irritability or fussiness
- Poor feeding
These symptoms may indicate a more serious condition requiring medical attention.
