Back in June of 2013, 11-year-old Sarah Murnaghan from Philadelphia received a double lung transplant during her battle with cystic fibrosis. And in the process, she changed the rules on organ transplants for children under 12.

Since returning home in August following her successful surgery, Sarah and the Murnaghan family have been working to sustain her quality of life, and they told Peter Johnson Jr. they've got a lot to be thankful for as 2014 approaches.

"It's such a relief to be here as a family again," said Sarah's mother Janet, who shared details of Sarah's great holiday and her love of playing in the snow.

When asked what she liked most about being home, Sarah herself answered, "Just being all together. And I get to play with them again, and do fun stuff with them."

Still, Sarah's journey toward recovery is far from over. She continues to undergo physical therapy five times a week to rebuild and strengthen her muscles. But, despite fractured bones which cause Sarah a lot of pain, she manages to make the best of things.

"Sarah never wanted to quit," said her father Fran. "And she gave us the strength. And together, as a family, it's very important to have a support structure."
