Turns out that Avery has Adenode virus, apparently it can be a pretty nasty bug.  I am so impressed with how well he has done with it though.  Typically he would have been a respiratory mess and requiring a much longer hospital stay.  Instead he is just having some vomitting, diarrhea and stomach pain.  I do feel bad for him but it is much better than having breathing issues.  We are hoping to be home by tomorrow.  Hopefully he has a good night b/c I am really getting sick of being in the hospital at this point.
