A carpool karaoke-style video of 50 mums and their children singing along to Christina Perri’s, ‘A Thousand Years’ is going viral.

The tear-jerking video shows children with Down’s Syndrome using Makaton (a form of sign language) in time with the heartfelt lyrics.

The video went live ahead of this year’s World Down Syndrome Day, which takes place from the 19th to the 25th March 2018, and seeks to popularise the social media hashtag #wouldntchangeathing because that’s exactly what 97% of people with Down’s Syndrome and their families report.

The mums featured in the video are all part of a Facebook group called “Designer Genes”, created for parents who have a child with Down Syndrome born in 2013/14. This group of mums decided to get together in a bid to show the world just how ordinary and fun life with the condition is. And the results are stunning.

The video called 50 Mums | 50 Kids | 1 Extra Chromosome, was uploaded on Friday and has since been watched more than 100,000 times on YouTube, and over a million times on Facebook. It’s also being shared by people all over the globe, including celebrities such as James Corden.

Becky Carless, one of mother’s in the video 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!”

Mrs Carless said: “We definitely wanted everyone to see it.

“The idea is, we are just normal mums, we love our kids, they love us, and they are just like other four-year-olds, we wouldn’t change them.”

She added: “The video turned out even better than we had hoped and the response has just been mad.”

Well done mums!
