Zion Harvey just became the very first hand transplant recipient at 8 years old.

Harvey lost his hands and feet when he was two to a life-threatening infection that caused multi-organ system failure. The Children's Hospital of Philadelphia (CHOP) shared his remarkable journey through a YouTube video.

"I wasn't always like this, when I was 2, I had to get my hands cut off, because I was sick," Harvey said in the video.

In an interview with NBC News, Harvey said the groundbreaking 10-hour operation performed on him earlier this month at CHOP was a dream come true. Apparently, he can't wait to hold his little sister with his new hands.

"My favorite thing [will be to] wait for her to run into my hands as I pick her up and spin her around," he told NBC.

As NBC reported, Zion Harvey's mother, Pattie Ray, was overcome with emotions when she saw her child being wheeled out of the operating room.

"When I saw Zion's hands for the first time after the operation I just felt like he was being reborn," she said. "I see my son in the light I haven't seen him in five years. It was like having a newborn. It was a very joyous moment for me. I was happy for him."

Apparently, Dr. L. Scott Levin and his 40-member transplant team spent countless hours practicing on cadavers before attempting what would be the world's first hand transplant operation on a child.

"The success of Penn's first bilateral hand transplant on an adult, performed in 2011, gave us a foundation to adapt the intricate techniques and coordinated plans required to perform this type of complex procedure on a child," said Levin in a statement.

Incidentally, Levin is also chairman of the department of orthopedic surgery at Penn Medicine and director of the hand transplantation program at Children's Hospital.

According to NBC, Harvey responded well to the surgery, as his doctors expected, and Levin only has good words for the young boy.

"I've never seen a tear, never an untoward face, never a complaint," Levin said. "He's always positive. And that, in and of itself, is remarkable."

"This is the end of the beginning, not the beginning of the end," Levin added. "We've made a big step forward with this operation."

Harvey would still need to visit his doctors regularly to ensure that his body is not rejecting the hands, E! News reported.

E! News caught up with Levin and were told that when he asked Zion Harvey why he wanted his hands, the boy gave a very simple yet profound answer.

"He said, 'I want to swing on the monkey bars!'" the doctor said.

"That's sort of a milestone for a lot of kids...Our hope is over time, indeed he will be able to do that!" the doctor added.
