Just curious, do you get your bloodwork done before the trip to UNC? Wonder if he feels a little stressed and it affects his bloodwork. That is a mighty jump! Although, it also makes one wonder how accurate the tests are. We have seen these leaps out of nowhere, too. No big growth spurts, no change in way meds are given, no undo stress, no illness at time of tests. Medical visits don't bother me. I get uneasy shortly after birthdays. I relive those awful days after his birth when we didn't know what was wrong. I remember how lifeless he looked. Once we were getting medical care, I never doubted they would fix it. It was the not knowing that was killing me. I think we all have a sensitive spots.
