-- In a happy coincidence, a pair of identical twins have given birth just 20 hours apart in the same hospital.
Becky Pistone and her sister, Rachael McGeoch, welcomed their children in adjoining rooms at Mount Auburn Hospital in Cambridge, Massachusetts.
"It's awesome and they are so [cute] together," Pistone, 34 of Cape Cod, told ABC News. "They seem to get a sense of calm whenever they're together. I think it will be really fun to have them together when they grow up."
McGeoch's son, William Charles Bubenicek, was born at 10:41 p.m. on Aug. 15.
His cousin, Andi Isabella Pistone, was born at 6:54 p.m. on Aug. 16.
Their mothers' due dates had originally been 13 days apart until McGeoch was induced on Pistone's due date.
"Becky [Pistone] drove up the morning on the 15th from Cape Cod and within two hours of her arriving to Boston, Rachael went into labor," McGeoch's husband, Bill Bubenicek, told ABC News. "As that was going on, Becky went into full blown labor."
Pistone, who had originally planned to give birth in Cape Cod, was admitted as a patient next door to her sister.
Now 1 month old, the babies have been visiting each other every week.
"We've been back and forth at least four times now, it's pretty special," Bubenicek said.
"Hopefully they'll be as close as Rachael and I have been," said Pistone, who is two minutes younger than her twin. "It's always been our dream for them."
