Mine too Truckerdoo! Exact same age too...it is so heartbreaking. She started getting sick on Thursday and I think is finally just about over it today.
I slept sitting up with her on my chest for three nights in a row...actually she slept, I didn't.
If she laid down for any period of time, she had to cough and cough to clear her throat, so I just stopped letting her lay down. I nursed with her as close to a sitting position as possible (never tried that before - ouch.).
We got a lot of use out of the bulb syringe. Suctioned her noce a lot for the first few days and even her cheeks during big coughing spells.
Dr. Sears says that a vaporizer is better than a humidifier and to keep it close to the baby. We didn't have one and just kept the humidifiers going full strength.
It does get better! Hang in there and the cold will run its course!
