The twins that saved their mother's life by kicking loose a tumor while still in the womb.
Unknown to her, Mrs Stepney, 35, had developed cervical cancer. Her unborn twins' constant kicking in the womb actually managed to dislodge the tumour.
It was only when Mrs Stepney was taken to hospital with a suspected miscarriage that doctors realised she had cancer.
They told her the babies had saved her life. Without them, the cancer may not have been discovered until it was too late.
Despite the doctors' advice to terminate the pregnancy so she could have a hysterectomy and start chemotherapy, Mrs. Stepney said
I owe my life to my girls, and that's why I could have never agreed with a termination."
Instead, she waited for her lifesaving treatment until they had been born.
Now the proud mother of year-old girls Alice and Harriet, Mrs Stepney has been given the all-clear.
