congested and coughing baby under two months?

Shanna
My son sneezes a lot and has been congested here lately. I've been using saline drops and sucking his nose out sometimes I may get something and sometimes I don't . He also has like a dry cough. What can I do to help him?
Also he had a little drainage come out onto his ear lobe maybe he has an ear infection ? Someone please give me some advice I'm a new mom just trying to figure out what's best for my son
