The miracle of childbirth just got a little bit more miraculous.
A pair of twins were born in Boston earlier this year — 24 days apart.
In late February, Lindalva DaSilva went into labor just 24 weeks into her pregnancy.
Fearing the worst, DaSilva was rushed to Tufts Medical Center, where doctors had no choice but to proceed with the delivery.
The first child, Alexandre, was born weighing just 1 pound, 10 ounces after a quick delivery, according to ABC News.
"They brought him to me to give him a kiss," said DaSilva, recalling the whirlwind delivery after just three painless pushes. "He was crying, but he was very tiny and I was very scared. I said to my husband, 'He's too tiny.'"
Babies born at 24 weeks have about a 50 percent chance of surviving, reported ABC News.
Doctors told DaSilva of a childbirth technique that could help save at least one of the babies’ lives: Giving birth to one and keeping the other inside, reported The Boston Globe.
"When you have a situation where one baby is born and labor stops, you are given this window of opportunity," Ralston said. "But it's a rare window. Most times, labor does not stop."
24 days later, Ronaldo was born weighing nearly three times his older brother’s birth weight, according to ABC.
"They're my miracle babies," said DaSilva of her growing boys. "Ronaldo because he stayed inside, and Alexandre because he's a survivor."
DaSilva is hoping to bring her children home from the hospital’s neonatal intensive care unit later this month — right around the time of their original due date.
