He may not have an extensive vocabulary yet, but almost two-year-old Wallace has the four most important words down: "Mama, I love you".
According to Huffington Post, Wallace's dad Mike Brownell says "sort of got lucky" in capturing the song, which came together spontaneously one night when Wallace's mom, Sydney, was working late.
According to Brownell, Wallace was missing his mum and kept saying "mama" and "I love you" - and the words eventually morphed into a musical collaboration.
Sydney said she had had a busy day at work, and all she wanted was to be home in time to put her son to bed.
"I was feeling sad and defeated, and then I got the video," she said. "My immediate reaction was tears of joy!
"I think working parents need a reminder - more often than we realise, we are missed and loved just as much as we love and miss [our kids]."
