FWIW, I had gestational diabetes with both of my pregnancies and it was severe (required insulin and very close monitoring...had 3 doctors appointments each week the last month of my pregnancy) with my daughter. Anecdotally, when looking at my friends with kids, gestational diabetes is more common in my friends with autie kids than my friends without them. Though that is a very small sample size
While I agree that almost everything has been falsely linked to autism, it stands to reason that there is likely something that really is. At least this is more plausible than migration patterns of geese.
