Congestion and mucous

Aja

Does anyone else’s baby sound congested a good portion of the time? She’ll also get mucous caught in her throat it sounds like but no other symptoms. It’s been like this since she was born basically. I just recently got a humidifier for my room that I plan on using tonight but wondering if other babies get like this? She’s 3 months

She also gets choked all the time on spit up. Wondering if it could he reflux as I had pretty bad reflux as a baby too
