Laura Kelly and Her Sister Alicia Got Positive Pregnancy Tests Two Days Apart With the Same Due Date, and Their Daughters Ended Up Sharing More Than That
Two days separated Laura Kelly’s positive pregnancy test from her sister Alicia’s in early 2025, and the two sisters were handed the same due date. Their daughters did one better: Alice and Lillian were both born at Bryn Mawr Hospital on the same day, Sept. 12, 2025, NBC10 Philadelphia reported.
In September, the cousins turned 1 on the same birthday, and the families celebrated with two separate parties.
Two Tests, One Due Date
Laura, who calls herself a “late in life baby” and is the youngest of her siblings, learned she was pregnant first. She told NBC10 she never expected her sister to get a positive test of her own just two days later.
The sisters were already patients at the same medical practice, and their due dates matched. Even so, Laura said the idea that the babies might actually arrive on the same day seemed like a long shot.
A Race Against Midnight
The two births took very different routes. Alicia was induced on Sept. 11 and was in active labor at Bryn Mawr Hospital, according to NBC10. She told the station the family had expected her daughter to come the following week.
Laura, meanwhile, was getting ready for a scheduled C-section, and her doctor had asked the hospital to have a room ready. Her delivery kept getting pushed back as emergency C-sections came in, and as midnight neared, it looked as if the cousins might miss sharing a birthday after all.
They did not. Both girls were born on Sept. 12. The sisters were in different rooms, but on the same day in the same hospital, and one of them joked to NBC10 that it “may have made hospital bill cheaper.”
Bryn Mawr Hospital, founded in 1893 on South Bryn Mawr Avenue in Bryn Mawr, Pennsylvania, is part of Main Line Health. Its labor and delivery area sits on the first floor and its maternity unit on the second, according to the health system. Both sisters delivered under that one roof.
Two Ways Into the World
Induction and scheduled surgery run on very different clocks. The March of Dimes says labor induction uses medicine or procedures, such as ripening the cervix or giving the hormone oxytocin through an IV, to start labor, and that the process can take anywhere from a few hours to a few days depending on how the body responds. Alicia’s induction, which began Sept. 11 and ended with a birth on Sept. 12, fell within that range.
The group recommends induction for medical reasons, such as a health risk to the mother or baby or a pregnancy two or more weeks past its due date, and suggests asking whether it can wait until at least 39 weeks if the pregnancy is otherwise healthy.
A planned cesarean is scheduled surgery. A typical C-section takes about 45 minutes to an hour and a half from start to finish and usually means three to four days in the hospital, according to Cleveland Clinic, which lists a previous C-section, a breech baby and certain health conditions among the reasons one may be planned.
Nationally, 32.4% of babies born in the United States in 2024 were delivered by cesarean, or 1,173,391 deliveries, according to the Centers for Disease Control and Prevention.
Alice and Lillian at One
With Laura’s surgery repeatedly delayed by emergency cases, the shared birthday stayed in doubt almost until the clock ran out, according to NBC10’s account of the day.
NBC10 did not report the babies’ birth weights, the time each was born or the sisters’ hometowns. What the families did share was the arithmetic: two pregnancy tests two days apart, one due date, two very different deliveries and a single birthday.
For their first birthdays, the families chose separate parties, giving each cousin her own celebration while the date on the calendar stays the same for both.
