A set of identical twins, Rowan and Blake, kept each other alive by holding hands in the womb. Hayley Lampshire, 27, and her husband Charlie from Kidlington, Oxfordshire, England, discovered their twins were suffering from a rare condition that could lead to their death with the risk increasing with every passing day of her pregnancy.

The twins shared one amniotic sac, instead of having one each in their mother's uterus while they were in her womb and Hayley was told the umbilical cords may tangle if they moved around, Fox News reported. Hayley and her husband Charlie were amazed when two separate scans showed them that the two boys were clutching each other and barely moving. When they went for more check-ups they saw that the twins were doing the same thing.

Rowan and Blake were born by caesarian section on Aug. 25, 2016, and they are doing well now.

Hayley, a primary school teacher, reportedly said: "My husband, Charlie, and I were heartbroken when we found out our babies were in danger. Because the boys were in the same amniotic sac, their cords could get tangled if they moved around, which would cut off their oxygen and food supply. Charlie and I were terrified at first, but we want to share our story to reassure others that there is hope, something that we struggled to find when doing our own research. So far they have been good at sharing, after all it saved their lives, but I’m sure it will be a different story when they get older."

She explained that at her time of pregnancy she was told that she had risks because she was carrying monoamniotic-monochorionic twins. They were told that a selective termination would be the last resort.

In most pregnancies the risk factor decreases after 12 weeks, but Lampshire's risk of losing her babies grew as they grew bigger. They could only be saved if they remained still inside the womb. Their mother and father were amazed to see them clutch on to each other. Their relieved mother said: "The boys are now doing really well and are growing so fast, and Charlie and I know how lucky we are to have them both here."
