The sisters were born joined at the abdomen, but a year later, doctors separated them—this is what the sisters look like today.

When Maggie and Dom Altobelli learned in 2020 that they were expecting twin girls, they were overjoyed. But their happiness soon turned to uncertainty when doctors discovered that the babies were conjoined and shared several important structures.

Addison and Lilianna were born on November 18, 2020, connected through the chest and abdomen. Their condition required highly specialized care at Children’s Hospital of Philadelphia, where a team of experts prepared for one of the most challenging operations of their lives.

The twins shared a liver, diaphragm, rib cage, and abdominal wall. Separating them would require months of planning, as even a small complication could put both babies at risk.

When the girls were about one year old, surgeons performed the lengthy separation operation. Fortunately, it was successful, giving each sister the chance to grow independently.

Recovery brought further challenges, including breathing support and close medical monitoring. But the girls gradually made progress, learning to crawl and eventually take their first steps.

Today, their journey stands as a remarkable story of medical expertise, family devotion, and resilience. What began as an uncertain diagnosis became a new chapter filled with hope for two little girls.
