A couple of very practical things:
Get a humidifier running in her room at night. It really helps!
Prop up the part of the crib/bed where her head is. Use big books or blocks. ONly about 4-5 " is necessary.
Take a long hot shower with her right before bed (or at least have her in the bathroom when the shower is going). THis acts like a super humidifier.
IF her nose is stuffy, use the 'nose bulb' to draw some of her congestion out righ after the shower.
GIve her LOTS of liquids to keep the mucous running.
YOu'll get through it!
GOod luck!
