The past couple of days, Andrew hasn't been feeling right. He's had generalized abdominal pain, and although he isn't vomitting or any other classic signs, I'm pretty sure he has appendicitis. It looks like we'll be heading to the hospital tonight. "yay."
*** Update ***
It turned out not to be appendicitis, but he did have an inflammation of his colon/colitis of which the cause has not yet been determined.
