They underwent an 11-hour surgery in June at Children’s Hospital of Philadelphia when they were 10 months old.
The girls were released from the hospital Monday after spending 485 days at the hospital in Philadelphia.
Erin and Abby will require additional surgeries as they mature, but the team at CHOP said they’re optimistic about their progress so far and about their long-term potential.
"The girls are inspiring," said mother Heather Delaney. "As their parents, it is very neat for Riley and me to have a front-row seat to this, and watch them overcome these incredible obstacles. We cannot wait to see what their future holds."
The Delaney family said the girls are doing well, and they’re excited to spend the holidays with them at home.
