Congestion?

Tara

My LO is 7 weeks old and she is sounding congested in her throat, you can hear it when she breathes and sometimes it makes her cough/gag. We have a cool mist humidifier in the bedroom. Should I talk to her doctor? I’m getting super nervous bc of the coughing and gagging that she does. Her nose isn’t runny, and she does not have a fever.
