Get some tissues. No, really. Do it.

San Antonio couple Samir and Stephanie Deais recently filmed their son, Alexander, singing "Remember Me" from the Disney film, "Coco," to an altar dedicated to his late baby sister, Ava Lynn, on what would have been her first birthday.

The Deais family told that their daughter was born with hydronephrosis, a kidney ailment, and died last May at 4 months old. 

Samir Deais said the film, about Dia de Los Muertos, helped their 4-year-old son deal with the death. 

"I couldn't be more thankful for the movie," Deais said to "It's made it so easy to understand for him and for us to explain to him in a beautiful way."  

Deais tweeted the clip of his son singing to Ava Lynn's photo on Dec. 30, when she would have turned 1 year old. Roughly a million people have viewed it.
