Miles and Natasha Collett are now preparing to bring the four babies home to their two adopted sons, Damien, 12, and Phoenix, 10.
Miracles come in pairs — of pairs — for this Indiana couple, who welcomed quadruplets into the world after struggling for years to conceive.

“We’ve always wanted a big family since we’ve been together; we just planned on one at a time,” joked Miles Collett, 29, of Mooresville during an interview with InsideEdition.com.
On Sunday, his wife Natasha Collett, 26, gave birth to quadruplets — Liam, Rowan, Harper, and Willow — after having trouble getting pregnant for the last five years.
Natasha Collett, 26, gave birth to her four babies Willow, Rowan, Liam and Harper last Sunday.
Last July, the Colletts found out they were pregnant after several rounds of intrauterine insemination.
Then, Natasha discovered she was carrying four babies.
"I would be lying if I said we were not terrified at first," Miles said, laughing. "I about passed out, I almost fell out of my chair. It was the quietest car ride home."
In fact, they already had two adopted children at home, Damien, 12, and Phoenix, 10. The Colletts had registered to be foster-to-adopt parents, and ended up bringing the brothers into their home as a permanent addition to their family.
Miles explained their journey with fostering children was part of what made them determined to have kids of their own.
“We’ve brought babies in and out of our home for the last two or three years, and every single time we have babies in our home, we get so attached we want to keep them,” he said. “Every time we lost the baby [to a different family], it was heartbreaking. It just about killed us.”
Despite being nervous about turning their family of four into a family of eight, Miles said they tried to take it one day at a time, and talked to other families raising quadruplets for advice.
"We’re running around like chickens with their heads cut off," Miles said. "It’s hard enough to prepare for one baby, but I don’t think anything could prepare us for having quadruplets."
The quadruplets were born eight weeks premature on Super Bowl Sunday — a day the family now calls “Super Baby Sunday” — and will remain in the NICU for another month or so as they learn to eat and breathe on their own before they can be discharged.

Miles explained their two adopted sons, Damien and Phoenix, have not yet been able to visit with the babies since the NICU does not allow anyone younger than 14 to enter, but they have had the chance to see the babies by video calling their parents as they held the babies up to the phone from inside the NICU.
“They’re beyond excited for them to come home,” Miles said.
