3:00 AM: We're home! She's coughing a lot, but her ANC was really high (11, which is the highest I can remember it ever being). The chest x-ray showed some haziness, but they don't think she has an infection--it looks viral. They gave her a dose of antibiotics and some tylenol, so her fever was gone by the time we left the ER. If she has another fever tomorrow, we'll need to head back for more antibiotics, and by tomorrow, they'll have more information from the blood culture. I'm going to bed!
