Two sisters give birth to identical girl twins within months of each other
A Pennsylvania family was left stunned when two sisters both gave birth to identical twins within months of each other.
Megan O’Brien, 29, welcomed Lilah and Josie on November 21 last year, followed by her older sister Sara Seyler, 32, who gave birth to Lennon and Parker just three months later in Doylestown.
The coincidence didn’t end with the timing of their pregnancies — both sisters also had twins.
Sara admitted she felt nervous telling Megan she was pregnant. Having already had one child, she didn’t want to “steal the thunder” from Megan experiencing motherhood for the first time. Despite this, the sisters enjoyed going through pregnancy together, finding comfort in having someone to relate to and share the experience with.
Megan, whose husband is a triplet, found out she was having twins first. Her surprise was doubled when she learned Sara was pregnant with twins as well. Megan recalled receiving the news during a friend’s bachelorette party:
“I answered the FaceTime, and Sara was crying. I thought, ‘Oh my god, what’s wrong?’ Then she held up the ultrasound picture — two babies! I got tears in my eyes. It was so cool that she was having twins too.”
The sisters say life with the new arrivals has been manageable, coming from large families where chaos is familiar, though they acknowledge it’s still an adjustment.
Sara, now a mother of three, said: “Some days are very difficult. I’m a stay-at-home mom, so having all three at once can be a lot. But it’s fun — definitely more positives than negatives.”
Megan, without a toddler to juggle, finds her situation a bit easier. “It’s been great,” she said. “We’re super blessed. Crazy and chaotic at times, yes, but to be a first-time mom to identical twin girls and share it with my sister — it’s the coolest thing ever.”
The odds of a woman having identical twins are roughly 1 in 250. Interestingly, a woman whose sister has had identical twins is twice as likely to experience the same phenomenon.
