This sweet video of a boy singing to his late sister has gone viral

Nobody likes to start their day off with tears, but this video is something you just have to see. Stephanie and Samir Deais from San Antonio caught their son singing a Coco song for his late sister, and it’s the ultimate tribute. Ava Lynn would have turned one this past weekend.

Stephanie and Samir recorded the tribute, which features 4-year-old Alexander singing “Remember Me” to a photo of Ava Lynn, without the little boy even knowing. His sister sadly passed away last May from a condition called hydronephrosis, which according to the Boston Children’s Hospital, sometimes occurs when urine backs up, or overfills into the kidney.

Samir shared the sweet video on Twitter, with the caption of “He’s only 4 years old and he understands. He didn’t even know he was being recorded. He just wanted to sing to her for her 1st birthday!” According to an article from The Huffington Post, the movie Coco — recently released by Disney — helped him cope and better understand the untimely passing of his sister.

The video quickly went viral, and according to the family, they were floored by the outpour of love for their family. We think this is just the perfect way to memorialize the sweet Ava Lynn. false

But for now, the song tribute is absolutely perfect. false

The couple is expecting another little girl soon, and as we have proof that Alexander is the best big brother of all time, we know she’ll be in good hands.
