I had the same issue with my little one, took her up the hospital and they said all is okay and newborn breaths are all over the place sometimes If your worried just go get her checked at the hospital to put your mind at rest
Ours also breathes like this but mainly when feeding. The midwife told me not to worry if baby sounds like earth vada and i’m guessing that’s what she meant! But maybe go to GP if you’re not sure
Try saline spray and a snot sucker xx
What’s her breathing like at the ribs, is she sucking in at the ribs? X
