Ron has a speech delay don't know how people are saying he hasn't, he didn't utter a word until he was 3! I have one child NT who was saying mama dada baba etc from 10months and was full on sentences at 18m and I thought she was a genius!! Turns out she is typical for her age, but I only had my son (who is autistic) to go on, I don't think she made up his speech difficulties, he's 4 in June, he can name objects and parrot words but he isn't able to converse, I have an autistic child, and I'll say once you meet one child with autism you've only met one child with autism,everyone is different,it's a huge spectrum of different abilities and disabilities, I have always believed Ron to be autistic but who knows what he's like when he's not on camera, autism is so much more than speech, alot of people have very little knowledge of autism, my son speaks fine now, but lacks in back and forth conversation too, he was delayed but was at a much better level than Ron is at 3 1/2, so it's not all based on speech, he's probably pretty high functioning and will improve with speech in time, he has also had intense therapy, that alot of children don't get because of long waiting lists and lack of money, I think she will reveal his diagnosis when the price is right for a book deal or TV show or something.
I could be completely wrong because as I said people with autism are so different, no two people are the same. But it's kind of silly when people say he can't be autistic because he has words now.
