If this isn't a display of happiness in its purest form, I don't know what is.

The famous song, You Are My Sunshine has been covered numerous times since its debut in 1939—but we may have found the greatest rendition to date.

Mother-of-five, Amanda Bowman Gray, has always been passionate about bringing the power of music into her home. After watching footage of her 10-year-old daughter Lydia, playing the guitar and singing to her 25-month-old son Bo, we understand why.

Since uploading her home video to Facebook on January 15th, Amanda’s post has gone viral, reaching up to 38 million views!

“My daughter Lydia was watching Bo while I was in the shower. Came out to this. If she didn’t have a guitar I don’t know if she would know how to babysit him. This is her go to. It’s proof that music therapy works. Bo is 25 months old and has a 12-word vocabulary. Every word he has learned has been through music and singing,” Amanda wrote in her post.

Lydia’s patience and gentle spirit paired with Bo’s adorable stature, backup vocals, and sweet sways leave us swooning over the siblings every time we hit replay—this video is pure gold.

According to Us Weekly, doctors were concerned Bo (who has Down Syndrome) would not be able to speak until the age of 3. Thanks to music, that hasn’t been the case.

"After evaluating Bo, the speech therapist said Bo was by far her most advanced Down Syndrome child speech-wise she has ever worked with over the past 30 years! She said never in her career has she had a 25-month-old with down syndrome have a 12-word vocabulary including a couple of them with two syllables," Amanda shared in a seperate Facebook post.

It’s obvious that the song You Are My Sunshine is representative of the love Bo provides his family. In a separate video posted to Amanda’s Facebook page, her and her husband can be seen singing the song to Bo during his time in the hospital due to heart surgery.

“We feel like he’s defying the odds,” the proud mother told ABC News. “Thanks to Lydia and her determination, she pushed forward with music therapy . . . We’re so proud of our kids.”

I think it’s fair to say Bo gives a little bit of sunshine to each of the millions of people watching, commenting, and sharing his musical debut.
