DS is only 4.5 months old, so who's to say? he's very social though. (as social as a 4.5 month old can be anyway)
he's not vaxed at all, and frankly, autism wasn't a reason on my list of them not to vax. it had more to do with the diseases themselves, and all the other multitude of questionable ingredients in vaccines that I think don't belong in a baby - or any other human -
DH and I are not autistic either - though I think I'd would test positive for ADD - DH was vaxed all the way, and on schedule. Many of mine were delayed until school age, not really on purpose, we just moved a lot and mom didn't bother until she had to
FWIW maternal grandmother had nearly all the diseases that there are vaccines for - measles, mumps, pretty sure she had whooping cough, I know she had scarlet fever - and she survived them. This to me, was a bigger reason not to vaccinate (see, people get sick, and they get better - and this was back in the 30's and 40's, before much of the newer meds and treatments)
We'll see about DS though, as far as any other illnesses. Thus far, he's not gotten more than a little cold.
