Virus' Last Stand?

Today I dropped Ronan off at daycare as usual and he seemed fine. Then, before my 2 p.m. class, I checked my cell phone to see that I had missed about five calls - it was the daycare to say that Ronan had thrown up three times and I needed to come get him. I went and got him and he seemed to be doing pretty well. He slept a lot when we got home, but then was up and doing pretty well after a couple hours. I just put him back down and he seems to be ok. We'll have to call the doctor (again) tomorrow, since we'll need a doctor's note to get him back in daycare and also to hopefully find out what's going on. However, I'm guessing that they'll just tell us that it's just a virus and he's fine.
