How to deal with excessive phlegm in a 1.5-year-old baby?

Patient's question:

No

Doctor's answer:

It is recommended to drink more water to thin the mucus and make it easier to cough up. Avoid feeding the baby too salty or too sweet foods. You can use appropriate expectorant medications, such as ambroxol oral solution or children's lung clearing oral solution, but avoid using cough suppressants. If symptoms such as fever or lethargy occur, seek medical attention promptly.
