stuffy nose- 3 weeks old

Casey
My babygirl will be 3 weeks old tomorrow, all day yesterday and through the night until now my baby has had a stuffy and runny nose. I can hear it with every breath she takes and I know it can't be comfortable. She feels warm to the touch as well, but I don't have a thermometer right now, I will have my SO pick one up when he comes home from work. But I'm wondering what you mamas think I should do for her? I suctioned her nose a few times last night, but at the hospital they told me not to do it too much as it will just make her nose more inflamed. I feel so bad for my baby! I'm a FTM so all of this is still really new for me. Any advice would be appreciated. She has also been more fussy than she usually is.
