4 week old congested at night

Caddie • Pediatric MA. TTC. Fur mom to 3

Anyone have trouble with their baby breathing from congestion/spitting up in the morning? My baby has quit breathing 4x from it. She wakes up and has thick whit mucus/spit up coming out of nose and mouth and she cant cry, just chokes until I use the nose freida and suction her. Usually she starts crying after that and can breathe. The nurse line said its normal and they will get it out. But it's so much and so thick it fills a quarter of the nose frieda atleast and its impossible for her to get it out on her own. It happened again tonight and o had to call 911. She was doing better by the time they got here and had good color and no retractions so I kept her home because the hospital wont do anything more than the dr at this point but it's so scary. I cant sleep because I worry itll happen and I wont be awake to help her get it out. Anyone experience anything like this before? (She doesnt have a cold or anything)
