A very special nurse is doing everything he can to make one little girl feel better — and he's warming thousands of hearts along the way.

Sophia Torres is currently fighting acute lymphoblastic leukemia, and one of her healthcare providers, nurse Brandon Waterhouse, went above and beyond [1] his medical duty just to make the little girl smile.

Even though Sophia's world has been filled with machine beeps, tummy aches, and IV wires during her past eight-month stay at Texas Children's Hospital, the 4-year-old girl has found an incredible support system in the hospital staff.

Recently, when Sophia couldn't fall asleep, Brandon pulled up a chair and began belting out Aladdin's "A Whole New World." Although Sophia was wrapped in a blanket with a mask covering her face, you can see the smile through her eyes as Brandon puts on a performance that rivals Prince Charming himself.

During Sophia's cancer battle [2], she has endured multiple surgeries as well as a stroke that affected her speech, eyesight, and ability to walk. But while the tiny fighter awaits a bone marrow transplant, she is surrounded by hospital workers who strive to make her smile any way they can — from playing with dolls to painting her nails.

"It's been a difficult journey for Sophia," said Sophia's dad, Jose Torres. "We are shocked, surprised that this video went viral. We felt happy and just amazed!"
