A mum was reduced to tears after her non-verbal autistic son 'realised his voice' for the first time. 
Millissa Hutchinson, 30, took to TikTok to share the special moment with her 150,000 followers. 
Five-year-old Keegan is seen in what Millissa described as the moment he "realised his voice".
The non-verbal superstar managed to say exactly what Millissa was asking when she said: "say more".
Keegan is heard in the video saying "more" multiple times and his own positive reaction sends his mum into a frenzy.
