Financial analyst Catherine Howarth was stunned when the midwife handed her daughter Sophia and she was as white as her brother.
The mum, a Nigerian, is believed to the only black mother in the world to have given birth to two white, blue-eyed children.
She said: ‘When Jonah was born, a genetic specialist said he was a one-in-a-million baby. He said it was extraordinary with my African background that I’d had a child with blue eyes and pale skin.
‘He calculated the possibility of it happening again was less than one in a million.
‘So when Sophia was born with white skin and blue eyes I was more than taken aback with shock. It seems the odds of it happening twice are millions-to-one. No-one has heard of a black mum having two white babies one after the other.’
While husband Richard, 37, an engineer, is completely white, the couple from Milton Keynes, Buckinghamshire thought their second child would be much darker than their first.
Catherine said: ‘When I had Jonah he was so white both Richard and I thought the midwife had given us the wrong child. But if anything, having Sophia has been even more of a shock because we were sure it couldn’t happen twice. I was stunned when I saw her blue eyes and light skin.’
Doctors were equally amazed when Sophia was born last March.
