Our carpool karaoke went viral

You probably saw the video - it's now had four million views! It's a wonderfully uplifting idea, created by 50 mums in the Down's syndrome community (and edited by one dad - Jamie!) which saw the world's heart melt for their beautiful, gifted kids. In our never-ending ambition to educate the world on what Down's syndrome really means, this video summed it all up to a beat. It means happy families. It means clever kids. It means sunshine and smiles and laughter and tears (happy tears!)Here, three of the mums featured in the video share with Bella magazine what it was like to see their kids go 'viral' ... and what a profound effect on people's understanding of Down's syndrome they hope the video will have.
