Six months ago, 4-year-old Jose Morales-Ortiz was struggling to say two-word sentences. Jose has severe autism, and he couldn’t have a conversation and wouldn’t answer to his name most of the time — all things that kids his age are supposed to be able to do.

By the end of June, though, it was clear something had changed.

Keith Joyce, his guardian, said Jose was able to tell him about the other kids at school and answer follow-up questions.

“The first time I realized I’d had a conversation with him, I cried,” said Joyce, 60, of St. Paul, Minnesota, who has been raising Jose since he was a baby and calls him “my guy.”
