This Mom’s Three Girls, Born Three Years Apart, Share the Same Birthday

Kristin Lammert is a mom to three girls—all born on the same day, but three years apart.

Her first daughter, Sophia, now 6, was born on August 25. With Sophia, Lammert, 32, was two weeks past her due date and had to be induced. When Lammert found out her second daughter’s due date was August 29, she had a strong suspicion her daughters would end up sharing a birthday—and they did.

“I had joked that she could come four days early and the family was like, ‘Well, yeah but that’s probably not going to happen on its own,’” Lammert, who lives in of Oviedo, Florida, told TODAY Parents.

Even more remarkable? Three years after welcoming Giuliana, now 3, Lammert, welcomed her third daughter, Mia, on August 25, 2021. “We were just in disbelief. The closer we got to Aug. 25 and the more that we joked about it at home, the more I wanted it to happen,” Lammert told the outlet. “Actually, Sophia said that she was going to get a sister again for her sixth birthday. She was wanting that to happen and I thought, ‘Well, it could.’”

The odds of all children having the same birthday are incredibly rare. “The Guinness Book of World Records holder is a family that have five siblings born on the same day and they listed that as being about one in a 17 billion chance,” Christine Greves, MD, an OBGYN with Winnie Palmer Hospital for Women & Babies, told TODAY, adding that only 5 percent of babies are actually born on their estimated due dates.

Mia’s due date was in September 2021, but having gotten COVID-19 at 10 weeks, Lammert’s third pregnancy was at higher risk for complications. “My doctor said up to two weeks early. That’s when I looked at the calendar and I remember turning to my husband and saying, ‘Oh my gosh, Nick, two weeks before the due date is Aug. 25,’” she said. “He’s like, ‘No way.’ That was the moment I was like, ‘She’s totally going to be born on the 25th.’”

The weekend before August 25, Lammert felt her ankles were swollen and she struggled with headaches. It was then that her doctors realized she had preeclampsia and suggested delivering Mia right away. Lammert says Mia loves listening to and smiling at her older sisters and she loves to watch them all interact.

According to Lammert, Sophia loves sharing her birthday with her sisters. “Sophia is very emotional about a lot of things in a good way. She appreciates the uniqueness and excitement of that,” Lammert said, adding that Sophia has loved planning birthdays with Giuliana. “She thinks that it’s very special. She just loves that she’s sharing her birthday with her sister because she’s now had three birthday parties that have been joint birthday parties.”

As for how Lammert handles the celebrations, she says that she makes sure each child gets equal gifts and guests. “I get them separate cakes so they each have candles to blow out,” she explained. “We try to separate it but make it a joint party at the same time. That way they both feel like special birthday girls.”

Sometimes she still can’t believe all three share a birthday. “It’s very unique. Honestly, I don’t understand it myself,” she told the outlet. “Sometimes I go and stare at their birth certificates. I’m like, ‘They actually all have the same birthday.’”
