My child was also the healthiest kid. No antibiotics or medications (even tylenol) ever in his life prior to d/x, a couple of very weak colds, and one flu? which made him throw up once... but that was a couple of weeks before d/x. Not sure if that one was the trigger or not, because he'd had the drinking and peeing syndrome for about 4 weeks before that. I also wonder whether my son had t1 coming down the pike for many months prior to d/x... maybe years (he was d/x'ed at 3 1/2). I remember the strange smell that came out of his room when he was sleeping at night.. I used to think that smell was his 'personal smell' and thought it was kind of spicy like a curry. But he had that ketone smell for more than a year before d/x... maybe longer. Of course as soon as he started getting insulin.. no more spicy smell.
