first cold 😔😷

Brittany
So my 2 month old has his first cold. Coughing sneezing runny nose, and has been getting a fever of 101 every night. It really didn't start until after his 2 month shots. But we also have been having crazy weather in GA, 50 degrees one day and 80 degrees the next. They don't prescribe cough meds for infants so what can I use for his runny nose and cough? I really hate seeing my little man like this 😢
