Lindsey,
That's great news!!!
I would imagine it could well have been his cold that caused the high reading, I also was concerned a little while back about my son's higher than normal bg, but have since accepted that blood levels increase post meal times in people with/without diabetes.
I thought that I was being a fool by writing my post, looking like some over-protective paranoid father who is continuing to worry about his children developing diabetes, but nothing could be further from the truth. My attention is drawn when they become unwell or feeling run down, and only test when neccesary. Having type 1 myself, does increase the chances of diabetes in one's children, albeit a small percentage, however I believe that being vigilant and aware of the tell-tale signs of onset diabetes is sensible, and shows a caring side of love towards our children.
Anyway, pleased the little fellow is keeping well, and just goes to show cars are dangerous, regardless of the size!
Best wishes
Nigel
