if you don't have a humidifier, go in the bathroom and close the door. turn the shower on all hot water and sit on the floor with your LO in just a diaper because it will be hot and let the steam work.!
Humidifier and warm baths before bed. Maybe let her sleep in her swing if she's comfy. It will get the congestion out. My son just got over a cold a couple of weeks ago that's what we did. Someone did suggest to put an onion slice in his sock and let him wear it. It's suppose to draw out sickness. I didn't do it but if you want to try it don't knock it.
