A two year-old girl with spina bifida just learned to walk by moving to the beat of the popular hit song “Baby Shark.”

Harper Comparin was born with spina bifida, a rare condition that causes the spinal cord to fail to develop properly, which makes walking extremely difficult. Though there is no cure for the condition, there are various treatment options that can make life easier, and Harper has already undergone multiple surgeries in her young life.

Her frequent trips to the hospital have taken a toll on Harper, leaving her nervous about being there and with little trust in doctors. Noticing this, Dr. Michelle Schultz of Johns Hopkins All Children’s Hospital in St. Petersburg, Florida started trying to find ways to regain Harper’s faith in doctors again.

“That was a big barrier we really had to cross at first, to regain her trust,” said Schultz, who has been treating Harper at the hospital. That’s when the doctor came up with the idea of using the popular children’s song “Baby Shark” to make Harper’s treatments more fun.

“I like the tune of that song,” she said of playing the song while Harper practiced walking on a small treadmill. “I use it like a metronome. I want her to walk to that beat. Doo doo doo! Pick up her speed, walk faster.”

The song was originally uploaded to the internet in 2016 by a South Korean educational brand, and video of it has since gone mega-viral with over 2.6 billion views. As Harper continued moving to the beat of the song, her trust in doctors started to return and she even started talking more.

On top of that, Harper is walking better than she ever has before.

“When I first saw her taking five, six, seven steps across the room, I was like ‘Are you serious?’” said Fred Comparin, Harper’s father. “She’ll now just walk up to total strangers and just say, ‘Hi!’ ”
