Conjoined Twins Who Were Separated: The Miraculous Journey of Eva and Erika

“Sometimes we fight. Most of the time, we get along.”

That’s how Eva and Erika, two bright third graders, describe what it’s like to be sisters. But their bond is unlike any other. Born conjoined from the pelvis up to the ribcage, their journey from shared bodies to individual lives is nothing short of miraculous—and their story is filled with laughter, resilience, and the kind of courage that inspires everyone around them.

A Birth Like No Other

When Eva and Erika entered the world, their parents faced a reality few can imagine. The twins were fused from the pelvis to the bottom of the ribcage, sharing a bladder and a complex connection between Erika’s small intestine and Eva’s large intestine. This meant that when Erika ate, her nourishment went to Eva, causing Eva to grow while Erika struggled.

A third leg—fused together with two conjoined feet—extended behind Erika, earning the nickname “butterfly leg” for its unique shape. Despite these challenges, their family described those early days as “fun,” filled with love and laughter.

The Decision That Changed Everything

At age two, on December 6th, 2016, Eva and Erika underwent a life-changing separation surgery. Their parents knew the risks: one or both girls could die. But the hope of giving each child her own life outweighed every fear.

“We were aware of the risks,” their mother recalls, “but if we have the opportunity to give them a separate, individual life, let’s take it.”

Surgeons removed the conjoined leg, using its tissue to help reconstruct Erika’s body. The operation was a success, and the twins began their new lives—each with her own unique personality, dreams, and future.

Learning to Be Unique

Eva and Erika are proud of what makes them different. Each has one leg and wears a prosthetic, but they’re quick to point out their special features: dimples, beauty marks, freckles, and their favorite Disney princess designs on their prosthetics. They laugh about the time they mistook a freckle for a piece of chocolate.

But being unique comes with challenges, too. Climbing stairs without railings is tough, and sometimes classmates stare at their “robot legs”—a term that makes them angry and frustrated. “It’s not creepy to have one leg,” Erika says. “It’s cool.”

Despite the stares, they keep moving forward, determined to show that they can do anything their friends can do—sometimes with a little extra effort.

School, Friendship, and Independence

In third grade, Eva and Erika sit close to each other, loving art projects and field trips. Their teacher, Mrs. Chiles, helps them find confidence and independence. “Being confident makes me feel like I’m normal,” Eva says.

At recess, Erika bounces basketballs, sometimes with her aide, while Eva navigates the big playground structure. They admit it’s not always easy to join in, sometimes feeling ignored or pushed back. But both girls are determined to keep trying, even when it’s hard.

At home, they ditch their prosthetics and scoot around, racing each other in playful shuffles. “Who can scoot faster?” their mom laughs. “They love having mobility at home.”

Celebrating Separation—and Sisterhood

Every December, the family celebrates the twins’ “separation anniversary”—a day filled with joy, reflection, and gratitude for the chance to live as individuals. It’s a day to honor their courage and the love that carried them through.

Eva is the social butterfly, into fashion and princesses, while Erika prefers skateboards and sports. They tease each other, argue over Disney pins, and sometimes call each other by their middle names in Spanish—just like any sisters.

Their differences are celebrated, not hidden. “Twins can be very different,” Erika says. “Eva wears dresses, I wear t-shirts.” Their personalities shine through in every conversation.

Finding Their Voices

Before the separation, Eva did most of the talking. Erika was quiet, overshadowed by her more outspoken sister. But after the surgery, Erika found her voice—literally. She began to speak up, ask for things, and express her own opinions.

“It’s almost like they had to be separated for Erika to reach her full potential,” their dad reflects. “Now, both girls are flourishing.”

Facing Challenges with Grit and Humor

Prosthetic legs aren’t easy. “Very uncomfortable,” Erika admits, and sometimes putting on the straps is hard. But she loves choosing new designs—always Disney princesses.

When classmates ask questions, the girls are happy to answer. “It’s our history behind us, but then we’re bringing it back in front of us and telling them,” Eva explains. Open conversations help break down barriers and build understanding.

Their teacher encourages them to challenge themselves, reminding them they’re strong and capable. “You got this,” she says. And they do.

A Miraculous Story—Still Unfolding

Eva and Erika’s journey is a testament to what’s possible when love, courage, and hope come together. They face extra challenges, but their determination and humor light up every room they enter. Their story reminds us that being unique is something to celebrate—and that miracles happen when families, doctors, and communities believe in the impossible.
