My 7 month old baby is coughing terribly has a runny nose. The coughing is what is worrying me cause it's just constant. It just started 2 days ago but last night he was up pretty much all night just miserable he couldn't stay asleep. It was like almost choking or gagging from coughing so much and so hard. I was ready to take him to the ER but all the pharmacys are closed cause it's Christmas. Should I take him anyway or is there any medicine that I can buy over the counter or any suggestions u can give me to help give him some relief?
