The emotional video shows Alex strumming a tune on his plastic guitar while he sings "Remember Me" from the movie "Coco." He didn't know he was being recorded because he was facing a photo of his sister.

Ava Lynn's first birthday would have been Dec. 30.

Alex's parents posted the video to Twitter, where it has been viewed more than 1 million times.
