Michael asked that question yesterday at the doctors office. He could not stop vomiting and learned exactly what it was. He did freak out a little, but in the end (no pun intended) it made him feel so much better he really didn't care.
Today, he's still home from school. He has to be fever free for 24 hours. I can tell he's getting back to his old self as his orneriness is starting to show. It has been bottled up for a couple of days.
Feel sorry for Sean as it starts to flow freely, I won't be here to deal with it.
