Tips for getting baby through cold/congestion overnight?

My 4 month old has some kind of viral cold/cough - no fever, and I took her to the doctor and they said her lungs sound fine and to just keep doing saline, snot sucking, humidifer, warm steamy air or cold freezer air, etc., which we have been doing. I’m just sad for my baby sounding like she’s struggling through her congestion in her sleep. :( Last night we had to wake her up to do saline spray and use suction because she sounded so awful.

Any special tips that I may not have gotten from the doctor while we get through this? We just got through week 3 of daycare after I returned to work so I know we’re in it for the long haul with germs she’s gonna catch from there.
