I'm not crying, you're crying.
A carpool karaoke lip sync video in support of World Down Syndrome Day features 50 moms and their children singing along to Christina Perri's multi-platinum selling track, "A Thousand Years".
The moms 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 "Wouldn't Change a Thing".
