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. Millissa, who lives in Cincinnati, Ohio, USA, said: "Keegan was really engaging with me and it’s why I started recording. "Due to him having autism, it’s hard sometimes to gain his full attention, but at that moment he was engaged." Millissa uses visual communication to help Keegan, including sign language and particularly Makaton signs. Makaton signs use speech and hand gestures to convey grammar and structure to spoken sentences. Millissa, who is originally from Walsall, West Midlands, UK, added: "I had noticed that he has been making me sounds so I tried to encourage him to say more with the Makaton sign. "As you can see that’s why he did. He realized he could do it and he was so excited. "It was one of the best moments of my life. "My reaction was so big because he thrives on praise and encouragement. "He’s my only child and for almost five years I’ve longed to hear his voice to break inside of his world and at that moment I did. It was the best feeling ever!" Millissa Hutchinson uses her impressive TikTok following to raise awareness for autism by regularly posting videos of her son and documenting day-to-day life with her family.
