hese Siamese sisters were born sharing something unimaginable — their heads 😱
Doctors warned their parents that survival without surgery was nearly impossible. And even with surgery, the odds were terrifying.

Erin and Abby Delaney were born in July 2016 in Philadelphia as extremely rare craniopagus twins, meaning their skulls — and parts of their brain membranes — were fused together. From the very beginning, doctors knew their case was among the most complex in modern medicine.

When the girls were still under one year old, a heartbreaking decision had to be made. Surgeons explained the reality to their parents: attempting separation could save them — but there was a real chance that only one child would survive.

Separating skull bones alone was difficult. Separating the brain was something closer to space-level precision. Neurosurgeons knew that an error of even one millimeter could result in death or severe, permanent damage.

The surgery lasted more than 10 hours and involved a massive team of specialists working in perfect coordination. Against the odds, the impossible happened — both girls survived 😍

What followed was a long and demanding road to recovery. Erin and Abby had to learn from the very beginning how to hold up their heads, sit, move, and function independently. Their brains had to relearn how to operate separately — a process that required years of therapy, patience, and unwavering love.

But perhaps the most beautiful moment came later.

For the first time in their lives, the sisters could hug each other. Their mother has shared that they often fall asleep holding one another — a sight she calls the greatest miracle of all 💖

Today, Erin and Abby are 9 years old. While their development differs slightly from their peers and they continue regular medical care and rehabilitation, they live joyful lives filled with laughter, love, and resilience.
