Watch: Dundee twins Ollie and Cameron play a starring role in a new World Down Syndrome Day video that is taking the world by storm

Dundee twins are among the stars of a new “carpool karaoke”-style video celebrating World Down Syndrome Day 2018.

Four-year-olds Ollie and Cameron, with mum Elaine Scougal, feature in the 50 Mums | 50 Kids | 1 Extra Chromosome video that has become an instant online hit since being released at midnight.

In the video, mums and their children use Makaton, a simplified form of British Sign Language, to join in with A Thousand Years, by Christina Perri.

The US singer was so thrilled by the video that she gave full approval for her song to be used.

The video has already succeeded in its aim of celebrating the lives and characters of children with Down’s Syndrome, having been seen over 200,000 times in just a few hours.

50 Mums | 50 Kids | 1 Extra Chromosome

Delighted to have been part of this great project for World Down Syndrome Day 2018! Please share as far and wide as you can to spread the message. The video is a carpool karaoke style lip sync video in support of World Down Syndrome Day featuring 50 mums and their children singing along to Christina Perri's multi-platinum selling track, "A Thousand Years". The mums are all part of a Facebook group known as "Designer Genes" created for parents who have a child with Down’s Syndrome born in 2013/14. They got together to show the world just how ordinary and fun life with the condition is and how they #wouldntchangeathing.The video was originally inspired by Singing Hands – a UK organisation who's videos have helped many in the group learn Makaton for supporting their children’s communication development. Makaton is designed to help hearing people with learning or communication difficulties using signs, symbols alongside speech.With thanks to the artist Christina Perri for her support and Singing Hands for the original concept.#wdsd18Also available on YouTube:

Elaine, 33, said: “There’s been a great reaction so far, which has been fantastic.

“There are so many stereotypes and prejudices and negative views still in society about Down’s Syndrome … (but) we wouldn’t change a thing about our kids.”

She said the video had been great fun to be involved with, adding: “It’s about spreading the word that conditions don’t define people. None of the children in the video are defined by having Down’s Syndrome.

“They are all children first and foremost and so that’s what the video gets across  — all you’re seeing are kids and their parents just having a nice time together.”

Elaine and husband Al, 30, live in Kirkton and twins Ollie and Cameron are already online stars thanks to the couple’s efforts to document their fun-filled lives.

Another of the mums who took part, Becky Carless, mother to Archie, 4, said: “We believe this video really does have the potential to be the most viewed across the world on World Down Syndrome Day this year, so we urge everyone to share share share to help us make it a success!”

World Down Syndrome Day is on March 21.
