Twins Conceived 3 Weeks Apart ๐Ÿผ๐Ÿผ

Have you heard of superfetation? We sure hadn't, but were delighted to read about twins Noah and Rosalie, born in England to proud parents Rebecca Roberts and Rhys Weaver.

This Washington Post article details how Roberts struggled with infertility for more than a year before finding out she was pregnant with a single baby, confirmed during her first ultrasound appointment. Five weeks later at her 12-week ultrasound appointment, the sonographer spotted something astonishing - Roberts was carrying a second, considerably less-developed, baby.

Unlike a typical set of twins, Roberts' pregnancy was diagnoses as superfetation - a rare condition in which a woman who is already pregnant conceives another baby.

Ordinarily, hormonal and physical changes during pregnancy prevent another conception from occurring. That wasn't the case for Roberts.

According to Roberts' obstetrician David Walker, "instead of stopping ovulation, she released another egg about three or four weeks after the first one, and the egg somehow miraculously managed to fertilize and implant in her uterus."

The true number of superfetation cases is not known, but according to a report published in 2008 in the European Journal of Obstetrics & Gynecology and Reproductive Biology, fewer than 10 instances of the phenomenon worldwide had been recorded at the time.

At just over 33 weeks into the pregnancy, the smaller fetus’s umbilical cord wasn’t functioning normally, which started to impact the baby’s growth. Doctors decided it was time to deliver. Although Roberts’s children technically had different due dates, she had a Caesarean section and gave birth to both babies on Sept. 17. Noah came first, weighing 4 pounds, 10 ounces. Two minutes later, his younger sister, Rosalie, arrived, weighing 2 pounds, 7 ounces.

Both babies were taken to the neonatal intensive care unit, where Noah remained for just over three weeks, and Rosalie stayed for 95 days.

Roberts noted, “even though they were born on the same day, there’s definitely an age difference between them. It's noticeable."
