How long has she been sick? There is a rule I implemented with anything, after my son's first cold that was actually an allergy attack that caused a double ear infection...if it's been more than three/four days, take her in.
Cool Mist humidifier
Pedicare Plug-in (they are non-medicated)
Infant vapor rub
Sleep Triangle for propping up during the night, this helps with keeping head elevated and nasal passages clear.
Hope she feels better soon.
