Five-year-old with autism speaks for the first time and his sense of pride is awe-inspiring

Since the video was first recorded, Micah has shown no signs of slowing his progress.

"It's been a day and a half now, and everything we ask him to say, he's copying," McGuire told Newsweek.

"He's not going out of his way to say anything on his own, but he's literally copying everything we say, which is crazy because he wasn't talking at all," McGuire continued. "Every now and then, he'd blurt out a word. But when I say 'wasn't talking,' he would go weeks without saying anything. This is crazy. He's been doing great."
