A 2-year-old baby has phlegm at night and has a cough. Take care to keep the room temperature around 26°C and give your baby warm boiled water and warm fruit juice to dilute the phlegm properly. Pat the baby’s back with your hand, from bottom to top, to make the phlegm in the lungs vibrate and make it easier for the baby to cough up sputum. If necessary, you can give your baby medications, such as honey-refined Chuanbei loquat paste, snake bile and Chuanbei liquid, and you can also choose to take pulmonary cough combination, brown combination, aminoglutethimide syrup, and carboxymethylstilbestrol oral solution. You can also give your baby nebulized inhalation, and choose to use chymotrypsin combined with budesonide nebulized solution to promote sputum excretion, and review and adjust the treatment plan at any time.
