Going to have my son tested. Is the test ok or painful? What is involved? Think my son might have it because he had several symptoms: intrauterine growth retardation, feeding issues, failure to thrive, and developmental delays (autism---which improved remarkably after diabetes diagnosis). Also, had ketones in his urine months before dx but normal a1c. Also, didn't eat any solid foods until after dx at 2 1/2 (only breastmilk)...then starting eating afterward! What would it mean if we got a dx anyway? No more insulin?
