While most primary school students enjoy nothing better than running and screaming around a playground with their friends, one ten-year-old is still having to learn how to form sentences after doctors said she would never be able to speak.

At just two-years-old, Savannah Dolor, of Montrose Road, Wealdstone, was diagnosed with global development delay – a condition that affects the development of skills such as cognitive abilities and motor skills.

Doctors told her mother, Kandy Dolor, that Savannah would never learn to speak and that she should prepare herself to never hear her own daughter’s voice.

Now ten, and studying at Woodlands School in Edgware, Savannah has defied all expectations, taking well to speech therapy - and has begun forming words and sentences.

Mother Miss Dolor said: “Even though the doctors said she’d never be able to talk, all I had was hope – I didn’t believe them, whether that was denial or determination I don’t know.

“I used to dream about hearing her voice for the first time, and I would wake up scared thinking about her future.

“I just kept on trying with her and we never gave up. I kept on saying ‘say mummy, say mummy’ until one day she did. It was the most amazing moment.”

Since her first words, Savannah – whose favourite subject is maths and who has a penchant for photography – has come on in leaps and bounds, learning more words and beginning to speak in sentences.

She takes regular speech therapy sessions at her school which her mother says are making a huge difference to their lives and her daughter’s confidence.

Miss Dolor added: “I cannot praise her school enough. They have done wonderful things for my daughter and have worked so hard to help her with her speech.”

Armed with her camera phone, she now films Savannah carrying out her day to day life after the determined media fan decided she wanted to star in her own YouTube vlog.

Savannah shares her videos with other children who have been diagnosed with the condition, and documents her life from baking cakes to having fun at the park.

Miss Dolor said: “She has a really big interest in the media, particularly because my mum, Delia Dolor, has her own show in St Lucia which Savannah has done some of the adverts for.

“She loves to talk as well and she’s got into healthy eating so we’re promoting that on her channel too.

“I'm so proud of how well she is doing and how hard she has worked to get to where she is now. Hearing her voice for the first time was fantastic, but still hearing her every day and hearing her speak better each day is wonderful."

The family, including younger brother and regular guest star Damiyon, now plan to invest in a new camera to continue the videos.
