But Rosa says there are some parents whose children may have an autistic disorder, and they don’t recognize it.

“If you can have a conversation, or if you can write, then you couldn’t possibly have autism. You couldn’t possibly have needs. And, just to get all of these misunderstandings out into the open and have an open discussion about it, it pretty much blew the top of my head off.”
