We are still waiting to hear the results of the MRI. The doctor assured me that the delay doesn't mean anything about the results... He said it is Monday and so they are probably really backed up and they usually have 1-2 other specialists look at it...so hopefully we'll hear something this evening.
We did hear that his urinary system is working just fine (they tested that this morning, too.)
He has slept almost all day. We weren't here for the MRI but apparently the little guy was crying a lot, so they had to give him something to calm down.
