Natalie and Leanne Paulson, 21, were due to have their first children a week apart.
But after Leanne went into labour a week late on July 29, her sister was taken into the same ward.
The twins were even in rooms next to each other while giving birth at Leicester Royal Infirmary.
Leanne had 8lb 8oz son Carter at 6.17pm and Natalie’s 8lb 2oz daughter Mila-Rose was born at 12.02am.
The sisters, who are not identical but look remarkably similar, are both care assistants and live up the road from each other in Branston, Leics.
They even found out they were pregnant on the same day.
Natalie said: “Leanne went into labour on my due date.
“I knew it would be close but I never imagined we would be in rooms next to each other giving birth. The nurses couldn’t believe it.
“It was an amazing experience because we’ve always shared everything.
“We ended up in the same room afterwards and I was holding her baby and she was holding mine.
“They even look quite similar.”
Leanne added: “I thought I’d be late going into labour but never that we’d go in on the same day.”
At home, Natalie’s partner Daniel Morgan and Leanne’s, Robert Walker, posed with them and the babies.
The births completed an amazing double for Leicester Royal Infirmary.
We told in April how identical twins Tina Hammond and Louise Huckerby, 23, also had babies just hours apart at the hospital.
