Erin Cheplak and Jill Justiniani, who are twin sisters, joked that they would give birth to their children on the same day throughout their pregnancies. They could not have foreseen that it would really occur. But indeed, that is precisely how things transpired. Jill cautioned her sister Erin over the phone shortly before Erin was scheduled to have a caesarean section on May 5. “This is no longer a joke,” Jill said.


“A water pipe in my home burst.” Within a few short hours of one another, the identical twin sisters gave birth to their first baby in the same hallway of the Kaiser Permanente Hospital in Anaheim, California. Not only were the kids born on the same day at the same hospital, but their sizes were also similar when they were first delivered. The boys, Jill Oliver and Erin Silas, were each born weighing 3260 grams when they were delivered.
The same increment of 50.8 centimeters was added to the height. Even though the sisters were taken aback by the proximity of the births of their kids, they emphasized that it was just part of the way things worked out in the natural world. The identical twins from Yorba Linda, California, who are now 30 years old have spent their whole lives walking side by side. Erin provided the following explanation: “We always did everything together.” – It was an amazing experience to be able to go through each new phase of life with another person. We are each other’s true best friends.

The sisters are now employed at a polyclinic as adolescent occupational therapists in that facility. Both of their tables are situated precisely opposite one another. They get together for lunch on a regular basis. The sisters say that being pregnant within eight days of one other was not planned, despite the fact that they were married a year apart and fell pregnant around the same time. When Jill and her husband Jan finally became pregnant after nearly a year of attempting to have a kid, it was the morning of the Cheplak family’s delayed wedding celebration in August 2021. Jill and Jan had been trying to start a family for over a year.

Due to the fact that their lives were so intertwined, it was only natural for the sisters to go through the challenges of pregnancy together. They found that it made them feel more at ease as well. Erin added, “Since these were both our first pregnancies, there were a lot of things that we did not know.”
