Question
A 2-year-5-month-old baby has been experiencing phlegm, cough, and a small amount of clear mucus since yesterday. The parents are unsure if it is an upper respiratory infection or the common cold and are asking for suitable medication options.

Based on the description, it may involve bronchitis or pneumonia. It is recommended to undergo lung auscultation, chest X-ray, routine blood test, and mycoplasma antibody tests for an accurate diagnosis, and to receive targeted treatment as prescribed by the doctor.
