Why does the baby always sleep with his mouth open?

Patient's question:

No

Doctor's answer:

It may not be caused by the child's nose. Due to poor ventilation caused by a stuffy nose, the child breathes through the mouth. If the child is in good spirits, there is no need to worry too much. If it still doesn't improve, it's best to have the child checked by an otolaryngologist to see if there are any abnormalities.
