Nicole Powell, a mom from Cabot, Arkansas, recently walked into a sweet moment her son Rayce was sharing with his little brother [2], Tripp. In the now-viral video she posted to Facebook, we see Rayce tenderly singing "10,000 Hours" by Dan + Shay to his baby brother [3], who has Down syndrome, and it's absolutely beautiful.

"This is how Rayce bonds with Tripp," she captioned the video. "He sings to him all the time. He swear this song is about him and his brother. He's singing, 'I'd spend 10,000 hours, and 10,000 more if that's what it takes to learn that sweet heart of yours. I might never get there but I'm gonna try if it's 10,000 hours or the rest of my life, I'm going to love you.' Love doesn't count chromosomes, or as Rayce says, 'Aren't we all different?'"

Watch until the end, and try not to shed a tear.
