A pair of twins born 50 hours apart in two different English hospitals beat million-to-one odds to survive, along with their mom, after a string of terrifying birth complications, The Sun reported Friday.

Donna Grove, 27, gave birth to baby Seth while 28 weeks' pregnant at Frimley Park hospital in Camberley, southeastern England.

But the child's brother Preston -- who was in his own womb sac -- arrived more than 50 hours later after Donna had been rushed to London for treatment.

Seth was not breathing when born on April 13. He then went on to develop a life-threatening intestine infection, a heart murmur and blood poisoning.

He was taken 40 miles (65 kilometers) by ambulance to St. Mary's in Paddington, central London.

Grove joined Seth the next evening, then the following day gave birth to Preston.

She then suffered a cardiac arrest after some of his womb sac fluid infected the blood stream -- a condition called amniotic fluid embolism.

Amazingly, doctors saved all three and they recovered during a ten-week hospital stay.

Medics put the odds of the trio's survival at a million-to-one. The twins' father, James Campbell, said, "The evening after the second birth was a dark, dark time. I feared I was going to lose them all."

Campbell, 26, a painter and decorator, proposed to Donna after she recovered from the traumatic labor.
