(CNN)At first, baby Noah was all lonely, growing beatifically in his mother'due south womb.
Noah's offset shut-ups, taken by ultrasound at seven and ten weeks into the pregnancy, showed 39-year-quondam mom Rebecca Roberts and 43-year-old dad Rhys Weaver the baby they had tried for more than a year to conceive.
And so, at three months into the pregnancy, Noah suddenly had visitor.
An ultrasound taken at week 12 showed that Noah had an unexpected little sis -- fraternal twin Rosalie.
"I got pregnant whilst I was already pregnant, which was admittedly crazy ... because that'southward non supposed to happen," Rebecca said.
Called a superfetation, getting pregnant while already carrying a baby is and then rare that one 2008 study plant fewer than 10 recorded cases in the world.
Doctors told the couple the babies were actually conceived about iii weeks apart, Rebecca said.
"They realized that the baby was growing at a consistent rate of three weeks behind the first one, and it was and then that they said to me, they think this is a superfetation pregnancy," she said.
"I couldn't believe it had happened to me," Rebecca added with a express mirth. "Simply it did -- it'southward lovely. It's similar winning the lottery."
Dad felt the aforementioned: "I was elated to be having one kid, just even more than so for twins. The task is done in one become! And then Rebecca did some research, and we realized how unique and how lucky we were."
An incredibly rare consequence
Superfetations are rare for a variety of reasons, said Atlanta gynecologist Dr. Lillian Schapiro.
First, women typically ovulate merely once per cycle, releasing 1 or more eggs simultaneously. If fertilization by the man'southward sperm is successful, the egg or eggs and then implant in the uterus, the pregnancy begins and no further ovulation occurs.
"If a woman has twins," Schapiro said, "2 eggs are released at the same time. And in the unusual case of triplets, those eggs are all released with one ovulation." Identical twins happen if a freshly fertilized egg splits.
In Rebecca's case, the egg was fertilized and implanted during the get-go ovulation, and "somehow she ovulated again during that same bike," Schapiro explained. "Another egg was also fertilized -- became some other embryo -- and at different times both embryos implanted in the uterus."
Some other reason superfetations are infrequent, Schapiro said, is that once the pregnancy begins, the uterus is no longer a hospitable identify for implantation. That ways the 2d embryo "must have managed to implant and grow at a stage when nosotros would not accept thought it would be able to grow."
"We take almost never seen where 2 embryos start developing at different times," Schapiro said. "That is just nothing curt of amazing."
Rebecca had only taken one dose of fertility drugs designed to stimulate ovulation before she conceived Noah. While that may be one reason for this rare occurrence, Rebecca said, it could besides but exist a "medical marvel."
'Tiny, tiny baby'
At first Rebecca and Rhys fretted over baby Rosalie's development in the womb, worried that being so far behind her bigger brother might impact her health at birth.
"Information technology could go either way," Rebecca said. "Considering the baby is so much smaller, there could be something incorrect with it and it might not survive. That'south usually the example.
"Only they said this baby's actually growing consistently," she said. "It was a relief. It was a great relief."
Born past cesarean in September 2020, both babies did have to spend time in divide neonatal intensive care units (NICU). Rosalie, who was born at a tiny 2 pounds, seven ounces, was sent to a specialty NICU about 15 minutes away from the NICU that cared for Noah, who was born at iv pounds, 10 ounces.
"She was a tiny, tiny petty baby just plumbing equipment in our hands, and fifty-fifty though he was tiny, you could run across that he was a much bigger baby," Rebecca said.
"It was very hard. I had a major operation and then our babies were in two separate hospitals likewise," she said. "So information technology was really difficult piece of work having to travel between them both."
Noah was able to come abode in three weeks, but niggling Rosalie remained in intensive care for 95 days, coming home simply before Christmas.
Today, at close to 7 months quondam, Noah is still ahead of Rosalie, but Rhys said, "She'due south a little trooper. She's got her own little personality, merely I have no real worries at all."
Noah'southward rolled over and is "actually showing signs of trying to clamber, and so he might be off soon, which will be fun," Rebecca added.
"They're both talking, which is actually really sweetness, because they talk to each other. Information technology'south lovely. They interact with each other really, actually well. It's beautiful to sentinel."
