The Truth’s Behind The Story 3 Sisters Were Born On The Same Day, Each 3 Years Apart – 8 Million To 1 Chance
When Kristin Lammert was pregnant with her second daughter, Giuliana, her due date was so close to her first daughter Sophia’s birthday that Lammert felt confident Giuliana would be born on the same day: Aug. 25. No one believed her — but she ᴡᴏᴜɴᴅ ᴜᴘ ʙᴇɪɴɢ ʀɪɢʜᴛ.
Three years later, her third daughter, Mia, also was born on Aug. 25, making the day three times as special for the family.
“We were just in disbelief,” Lammert, 32, of Oviedo, Florida, told TODAY Parents. “The closer we got to Aug. 25 and the more that we joked about it at home, the more I wanted it to happen. … 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.’”
Each girl is exactly three years apart: Sophia is 6, Giuliana is 3 and Mia is almost 2 months old. One family having three children born on the same day is so uncommon that it’s hard to estimate the odds of it.
“It is ᴇxᴛʀᴇᴍᴇʟʏ ʀᴀʀᴇ. … We’ve spoken to some statisticians and they say it’s really hard to calculate,” Dr. Christine Greves, an OB-GYN at Orlando Health Winnie Palmer Hospital for Women & Babies, who is not Lammert’s doctor, told TODAY Parents. “Tʜᴇ Gᴜɪɴɴᴇss Bᴏᴏᴋ ᴏF Wᴏʀʟᴅ Rᴇᴄᴏʀᴅs 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.”
Greves also noted that just 5% of babies are born on their due dates. Sophia was born two weeks after her due date on Aug. 25 when Lammert was induced. When Lammert learned she was pregnant with Giuliana and her due date was Aug. 29, she suspected Giuliana could arrive sooner.
In 2018, they held Sophia’s third birthday celebration the weekend before her birthday. After the party, Lammert went to the doctor and learned that her ʙʟᴏᴏᴅ ᴘʀᴇssᴜʀᴇ ᴡᴀs ᴇʟᴇᴠᴀᴛᴇᴅ. Mᴇᴅɪᴄᴀʟ sᴛᴀFF ᴅᴇᴄɪᴅᴇᴅ ᴛᴏ ɪɴᴅᴜᴄᴇ her and, at 10:30 p.m. on Aug. 25, Giuliana arrived.
“She almost didn’t share the same birthday, When that happened alone that was ᴘʀᴇᴛᴛʏ ᴄʀᴀᴢʏ and exciting.” she said
Little Sophia, who was 3 at the time, felt delighted. Since then, Sophia has been gleefully planning their co-celebrations.
“She thinks that it’s very specialShe 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.”Lammert said
This year, the Lammerts planned the birthday party the before Aug. 25. Following it, Lammert ᴡᴏᴋᴇ ᴜᴘ ᴀɴᴅ ɴᴏᴛɪᴄᴇᴅ ʜᴇʀ ᴀɴᴋʟᴇs ᴡᴇʀᴇ ᴇxᴛʀᴇᴍᴇʟʏ sᴡᴏʟʟᴇɴ ᴀɴᴅ sʜᴇ ʜᴀᴅ ᴀ ʜᴇᴀᴅᴀᴄʜe. Her doctors had been ᴄʟᴏsᴇʟʏ ᴍᴏɴɪᴛᴏʀɪɴɢ ʜᴇʀ ʙᴇᴄᴀᴜsᴇ sʜᴇ ʜᴀᴅ C.O.V.I.D-19 when she was 10 weeks pregnant and they knew pregnant people who ᴄᴏɴᴛʀᴀᴄᴛ C.O.V.I.D-19 ᴡᴇʀᴇ ᴀᴛ ʜɪɢʜᴇʀ ʀɪsᴋ ᴏF ᴄᴏᴍᴘʟɪᴄᴀᴛɪᴏɴs. It also meant that Mia might arrive before her September due date.
“Although Mia was thriving, I ɢᴏᴛ C.O.V.I.D-19 at the beginning of my pregnancy. I was only 10 weeks along, and after that, I was being ᴄʟᴏsᴇʟʏ ᴍᴏɴɪᴛᴏʀᴇᴅ Fᴏʀ ᴀɴʏ ᴄᴏᴍᴘʟɪᴄᴀᴛɪᴏɴs that may [have] come about,” Kristin explains.
“In the final days of pregnancy, I developed ʜɪɢʜ ʙʟᴏᴏᴅ ᴘʀᴇssᴜʀᴇ, a constant ʜᴇᴀᴅᴀᴄʜᴇ, ᴀɴᴅ ᴇxᴛʀᴇᴍᴇ sᴡᴇʟʟɪɴɢ,” she continues. “I got induced two weeks early due to ᴘʀᴇᴇᴄʟᴀᴍᴘsɪᴀ, and that was honestly a complete sʜᴏᴄᴋ. Mia was due September 8, 2021, and she was born on August 25, 14 days early.”
With three of their daughters now sharing birthdays — a likelihood that has about an 8 in 1 million chance, according to University of Minnesota sociology professor Rob Warren — Kristin says she and her husband Nick were left stunned.
“We always knew that we wanted to have three children three years apart, but we certainly did not plan for them to share the exact same birthday,” she says. “You never know how fertility will work itself out, but we specifically ‘chose’ to not try for our third until it would possibly cause us to have a September due date. But, clearly, baby Mia had a plan of her own.”
