Hello doctor. My nearly 11-month-old son had a runny nose and cough in the early morning, at first he gave me cold and flu syrup for 4-5 days but it still didn't help. I switched to cough syrup for 5 days and a runny nose. If the baby drinks, the runny nose will help, but if not, the nose will run again. Please ask the doctor, in case the child takes cough syrup, the runny nose will help, if not, will it be again, do I need to go to the doctor? Should I take antibiotics? The baby is still eating and sleeping normally. Thank you doctor, hope to hear from you soon.
