These photos are going viral because they bring all the joy.

When these little girls had their portraits taken months ago, no-one knew what might happen next. But now, there’s been a joyful reunion.

As three little girls gathered to get their picture taken on Saturday, the mood was quite a bit lighter than the last time the children were photographed together just a few short months ago.

Back then, Rheann Franklin, 6, Ainsley Peters, 4, and Rylie Hughey, 3, each battling cancer, came together for an emotional photo session in April with Oklahoma photographer Lora Scantling. The image taken that day, after the girls met for the first time in Scantling’s studio, went viral, touching the hearts of people all over the world.

When the girls reunited on Saturday, it was to share in happy news: In July they confirmed they are each in remission.

To celebrate, they got back together with Scantling to put an even more positive spin on thebeautiful scene that went viral earlier this year.

"The shoot definitely felt different,” Andrea Peters, Ainsley’s mom, told TODAY.com. “It was full of more hope and we know how much the girls have impacted the world. They've brought more knowledge to everyone that even the littlest fighters are full of strength."

“At the first shoot, it was nice to see the other kids, but sad not knowing what their outcomes would be,” Bridget Hughey, Rylie’s mom, says. “This time, I felt a lot of relief knowing that the girls are going to be OK.”

Four months after embarking on this unexpected and remarkable journey together, Scantling said she, fellow photographer Christy Goodger, the little girls and their mums are now like old friends.

"We have formed a bond that will probably last to the ends of time,” Valerie Franklin, Rheann’s mom, agreed. “Cancer parents — spouses, children, etc. — are a lot like major disaster survivors and tend to band together as much as possible.”

Franklin said there are many playdates in their future, and the mums keep in touch frequently to check in on one another and share updates about how their girls are feeling.

Hughey summed up the future for the group. “Even though we all have a long road ahead of us with treatments, scans, and tests for basically the rest of their lives, it feels amazing knowing that we are all walking toward the finish line.”
