Talk to your doctor: In babies who are only a few weeks old, it can be hard to tell if symptoms are serious or not. Nasal congestion is quite common, but tell your doctor at your next check-up. If your baby develops a fever as well, call right away rather than waiting a couple of weeks 'til your next appointment.
