From one green mama to the next... aren't colds miserable? It sounds like you're doing everything I do when I get a cold too. You can try putting a humidifier in your room at night or propping your head up with an extra pillow, but otherwise just make sure you drink a few extra cups of water every day (because you're constantly thirsty from nursing if you're anything like me, and if you're mouth-breathing at night that will dry things even more) and remember that it will go away soon. As for your baby getting it, she'll get over it soon because your breastmilk contains antibodies for it.
