Boston, MA (CNN) - In Boston, a set of twins born 24 days apart are healthily, thanks to the efforts of doctors who performed a rare surgery to save both children.
They are twins, but they don't share a birthday. In fact, Alexandre is more than 3 weeks older than his brother Ronaldo, but both boys are thriving after a rare and risky delayed delivery that has exceeded every expectation.
Sabrina Craigo, M.D. - Tufts Medical Center: 'This was unique in many ways, including that both twins are doing well.'
The challenge began when mom Linda DaSilva went into labor only 24 weeks into her pregnancy. Doctors at Tufts tried to stop the contractions, but 4 days later a very premature Alexandre was born.
Linda DaSilva - Mother: 'We were praying to hear his cry, and we did and it was a relief because knew there was 50% chance of not surviving.'
Doctors placed baby number one in intensive care and told mom and dad that it was time to consider keeping baby number two in mom's womb a little longer.
Linda DaSilva: 'I thought it was absurd! I said I don't think, didn't know this was possible.'
But doctors explained that a delayed twin delivery could be done, and Linda was a perfect candidate.
Ronaldo Antunes - Father: 'He's like leave him there, he is fine, his heart is beating well. So, okay, then we start praying.'
A healthy Ronaldo would be born 24 days later weighing in a full pound more than his big brother
Gina Geis, M.D. - Tufts Medical Center NICU: 'We try to tell moms be grateful for everyday you're still pregnant and we can get you as far along as we possibly can and this is just a perfect example.'
