These twin sisters were born conjoined at the head 😱. Separating them was an extremely complex surgery, as doctors had to divide not only their skulls but also parts of their brains 😲. The girls were just 10 months old when surgeons performed the operation, and miraculously, it was a success 😍.
Now, the girls are 9 years old. While their development is a little different from other children their age, they live much like any other kids 💖.
Erin and Abby Delaney were born in July 2016 in Philadelphia as one of the rarest types of conjoined twins — craniopagus twins, joined at the head.
Their skulls and portions of the brain lining were fused together, and doctors knew from the beginning that without a highly complex surgical procedure, the girls wouldn’t survive long.
When the babies turned just one year old, doctors made a life-changing decision — to attempt their separation. Their parents were told the harsh truth: the chances of both surviving were very slim, and one might not make it.
Separating their skull bones was one thing, but dividing brain tissue was a challenge of the highest level. Even a millimeter’s error could mean death or severe disability.
The surgery lasted more than ten hours. A team of neurosurgeons and specialists worked with extraordinary precision. Against all odds, the operation was successful — both girls survived.
Afterward came a long road to recovery. Erin and Abby had to quickly learn basic skills that other children already had — holding up their heads, sitting, moving.
Their brains had to “relearn” how to function independently. It wasn’t easy, but with the support of doctors, parents, and loved ones, they made remarkable progress.
The greatest miracle of all was that for the first time, the sisters could hug each other. Their mother often says that seeing them fall asleep in each other’s arms is the most precious sight in her life.
Today, at 9 years old, Erin and Abby continue to grow and thrive. While they still undergo therapy and regular rehabilitation, they also learn, laugh, play, and live like ordinary children.
