Twin sisters have given birth on the same day with the same doctor - and one of them has even had twins.
Lauren Kozelichki and Lisa Boyce live just 10 minutes apart from each other in St. Louis, Missouri, US.
They were born just one minute apart and share almost everything.
Lisa gave birth to a little boy she has named Benjamin via cesarean section at 1.39am after two days of labour.
Ten hours later, Lauren had a scheduled cesarean and brought Vada and Cooper into the world - also just a minute apart.
All the babies were delivered by the same specialist.
Lisa told Good Morning America : "I don’t think we realized it was even that big of a deal because we’re so used to sharing everything. "We just thought, ‘Oh this will be fun.'"
Lauren added: "We kind of figured Lisa would deliver about three weeks earlier because at the time we didn’t know we’d have twins.
"It didn’t cross our minds at all that we’d ever have babies on the same dates."
Benjamin is Lisa's first child while Lauren already has to kids.
But the mums said they hadn't planned things to turn out the way they did.
The sisters even ended up in rooms across the hall from each other as they recovered from the births in hospital.
Lauren and Lisa are now looking forward to throwing shared birthday parties for their babies.
