My 9-month baby starts to cough with some phlegm for an hour after her 1st bottle of milk. also a bit of stuffy nose. no other sympton of flu. what2d?

Happy baby or not?: If a baby always coughs after eating or drinking, he may have some reflux problem. If a baby is normally fine, with no cough, then a little stuffy or runny nose is usually a cold. Sometimes it can be allergies, and it can also be a strep throat. A happy baby with slight symptoms can be watched a couple of days, and then see the doctor if not all well. The doctor might then do a strep throat test.
