If this isn't the most adorable video EVER. I saw this going around Facebook the other day, and I've probably watched it a hundred times. This little boy is special needs, but that doesn't stop him from loving music and singing with his sister! I love how she pauses and lets him sing with her! This is too freakin' adorable! Seriously, if this doesn't warm your heart, I'm seriously going to be worried about you haha.
