Baby congested at night

Megan

I'm 5 weeks old has been getting really congested at night. He's been snoring really loud and sounds very stuffy when he wakes up for feeds. I've been trying to clear it out with the Frida baby nose sucker but it hasn't seemed to completely resolve it. He has a doctor's appointment on Monday I'll talk to his doctor about it.

Any recommendations in the meantime of how to help the congestion?
