Mucus in children usually occurs in the rainy season and some other days of the year. This mucus is not harmful but can prevent young children from breathing, eating and sleeping properly.
Mucus in children is very common in babies and children up to 5 years old. Mucus is a defense mechanism of the body against infections. When a virus comes in contact with and inflames the airways, the answer is to produce that gelatinous material. In turn, it traps germs to be expelled outside.
