Under the weather

I started getting a cold/sinus infection this weekend, and have felt under the weather.....last night Molly woke up in the middle of the night crying, coughing, and with a yucky nose. I rocked her and we both fell asleep in the glider....this is how Daddy found us! Sickness is NO FUN! I still feel terrible, and now I have a sick baby on top of it.....how long until it passes onto another member of the family???
