I call false.
Both moms I know with autistic children are fit thin and one is a lawyer married to a doctor. I think this article is designed to blame the parents as being fat and stupid for autism.
This is not right.
I don’t think the study said that all kids on the autism spectrum have mothers who are overweight or have Type II diabetes (or both). I think they said the risk was significantly increased.
Your example of 2 kids isn’t much to go on to try to claim that the research is false.
Anecdotal...
