For a little while my sister fell into the vaccine trap about my nephew, insisting that he talked, etc. up until one vax or another, but she was wrong--he DIDN'T talk until he was, like, 4, and people I know, who KNOW--having MR kids, LD grandkids, etc.-- knew "something" was wrong with him by the time he was 2. Is it autism? Well, I find that debatable; I call it ADHD with a twist. 25 years ago, he wouldn't have been called autistic, nor would/were a lot of other people I know, hence at least a partial explanation of the rise in numbers.
