"Gunk" in newborns nose

Carla
My 3 week old has some "gunk" in the back of her nose. Her nose isn't running or anything like that, just "gunky". We are using a humidifier, letting her sit in bathroom while we shower so she can breathe in the steam to help clear it out, and nasal drops / aspirator. There are times where I feel like she is struggling to breathe. What else can I do?
