Rare conjoined twins who survived separation surgery despite just 2% chance of survival have graduated kindergarten. Mum Heather Delaney, 33, learned at just 11 weeks pregnant that she was carrying conjoined twin baby girls.
Connected at the head - known as craniopagus twins - the babies had a low chance of survival, but fought against the odds. Heather gave birth to daughters Abby and Erin at 30 weeks in July 2016 - who weighed 6lbs combined.
Heather and her husband, Ryley Delaney, 30, a landscape foreman, were thrilled despite their daughters having to remain in the neonatal intensive care unit at Children's Hospital of Philadelphia (CHOP), Pennsylvania - ten hours from home. In June 2017, the girls underwent a rare, pioneering procedure to separate their skulls - and despite the risks, the 11-hour-long operation at CHOP, was a success.
