Treatment Recommendations for Pediatric Respiratory System Infections

How to deal with a baby’s whistling cough accompanied by coughing when breathing out?

The child has a cough and runny nose, possibly due to cross-infection during school, accompanied by symptoms of phlegm in the throat. After taking oral medication for three days, the symptoms improved. However, they recurred at school, this time with symptoms of phlegm in the throat. The child was given a lung-clearing syrup, but because it was too bitter, he was reluctant to drink it. Later, he was fed Lanqin, which resulted in him vomiting everything he ate. He reported stomach pain and phlegm in his throat. After a detailed examination at the hospital, it was diagnosed as significant bronchitis. He was given intravenous fluids for a day and prescribed pediatric cough syrup, but vomiting occurred again after drinking it. I am seeking professional advice and treatment guidance.
