In a heartstring-pulling video that's going viral, a little boy named Alexander sings the song "Remember Me" from the 2017 Disney-Pixar film Coco to his late baby sister, Ava. Dad Samir Deais shot the video and shared it on Twitter on December 30, noting that his son may only be 4 years old, but “he understands. He didn’t even know he was being recorded. He just wanted to sing to her for her 1st birthday!”

If you're not familiar with the lyrics from the animated flick, they read, “Remember me, though I have to say goodbye, remember me, don’t let it make you cry. For even if I’m far away I hold you in my heart, I sing a secret song to you each night we are apart.”

It was back in December of 2016 that the Deais family welcomed Ava, but in May, the baby girl tragically passed away at just 4 months old after developing hydronephrosis, a condition that causes kidneys swell due to a back up of urine, according to the National Kidney Foundation.

Now, the incredibly sweet, heart-wrenching clip of Alexander has racked up nearly 58,000 retweets and more than 149K likes. Tons of Twitter users wrote supportive messages to the San Antonio, Texas-based family.

“My wife and were literally brought to tears seeing how much love Alex and Ava and our family has received. We were FLOORED last night!” Deais shared on Twitter on Tuesday, January 2. “I couldn’t [be] more thankful. Thank you to everyone from our little family!”

It's heartening to know that the Deais and his wife, Stephanie, are expecting their third child and "rainbow baby." Back in October, the proud father shared on the social media site that they cannot wait to welcome their daughter Stella Grace Deais.

Wishing nothing but happiness and health to this perhaps "little," but quite big-hearted family!
