Mom has given birth to 4 daughters over 9 years on the exact same day

In the Lammert family, there is one day each year that is more special than the rest — it’s Aug. 25, the day of all four of the Lammert daughters were born. No, they’re not quadruplets. Each girl was born on the same day, exactly three years apart.

That’s right — Sophia, 9, Giuliana, 6, Mia, 3, and Valentina, 2.5 weeks old — have the exact same birthday.

“I’m still surprised,” says their mother, 35-year-old Kristin Lammert of South Carolina. Baby Valentina was due Sept. 25, and arrived a month early on her sisters’ birthday.
