Ugh..... Is this sickness crap ever gonna leave my house? My mom is sick with the flu or something and now my son is running another fever. It was 101.7 when I just checked it. The only one that has not gotten sick in my house is my daughter. What is going on here? He just got over a virus. I thought something was up yesterday when my son didn't eat that much at all.
