What are some good methods to clear the lungs when a baby has a severe cough?

Patient's question:

The baby is 14 months old and has been coughing badly these last couple of days. There is phlegm in the throat. After taking the lung-cleaning syrup, they vomit. The coughing also causes them to spit up milk. The doctor is asking for good methods for clearing the lungs now. Urgent

Doctor's answer:

Your condition is generally caused by a cold-induced tracheitis. Currently, it is important to take medication properly and coordinate with using a nebulizer. Take some medication that helps recover from the illness, preferably in coordination with a nebulizer, drink more water, and maintain a light diet for gradual treatment. It is necessary to first reduce the inflammation to facilitate recovery. Pay attention to keeping the child's diet light and avoid stimulating the throat area, which is not conducive to recovery.
