7:20 PM: Quick update. When I picked up Sophie from day care today, she started throwing up on the way home. She threw up 3 times in the car (although it wasn't terribly messy) and has vomited 7 more times since we got home. At first the doctor said to give her zofran and watch for signs of dehydration, but when I called back to say she hadn't kept the zofran down, he thought it would be a good idea to take her to the UNC ER tonight, where they can administer fluids and zofran by IV and make sure she's doing okay. I'm happy to do that, because we're worried about how pale and lethargic she is. She doesn't have a fever, and I took her blood sugar and it was fine. He said they probably wouldn't admit us but to pack a bag just in case. I figure they probably will admit her, since they prefer to play it safe. So we'll see! We'll leave as soon as I get packed, and we'll keep you posted.
