How to for a baby

Patient's question:

No

Doctor's answer:

Infants and young children cannot cough up phlegm; most of the phlegm is swallowed, so they need help to expel phlegm when they have respiratory infections. Methods include:
Ventilation method: Open windows at regular intervals to maintain fresh air and relative humidity in the room, which helps keep the respiratory mucosa moist and promotes the beating of cilia on the mucosal surface, aiding in phlegm expulsion.
