3 week old has 99.8 fever

Ke

My theee week old has a 99.8 degree fever. I think she has a cold - lots of sneezing and boogies. She sneezed this morning and one flew out. Her nose is to small and her cartridge is to thick to get a bulb in there so I’m hesitating to use saline.

Any recommendations? Currently feeding her listening to this poor girl struggling to breathe through her nose (she sounds like a pug) and she’s down to her diaper. 99.8 is with rectal temp.
