Update

I took Dylan back to the dr last Friday. His white cell count was back down. Down in the normal range. His dr was even really happy about how much it had come down!
She did say that next time he gets a fever, to bring him in. We will do another bloodtest and also a urine test to make sure kidneys and bladder are ok!
I do feel quite a bit better and more confident that it isn't anything scary serious. I asked her point blank and she said again, that she was really confident it wasn't anything that I was scared of!
Thanks for the nice thoughts~!
