Mrs. Wulf discussed with her husband the possibility that she may not be around as the boys grow up. She added: 'I think I'm a much better parent now than when I was younger. I'm not working. I'm not under stress. I'm ready to enjoy them.'

"Age is a number," said Mrs Wulf, who married Scott Wulf, 48, seven years ago. "You're as old as you feel."

She had her 11th child, Ian, her husband's first, three-and-a-half years ago, with help from fertilization expert Dr. Christo Zoubes.

"I hate to raise one alone, without a sibling," said Mrs. Wulf, a diabetic who has been blind from birth. Records suggest the oldest woman ever to give birth was 66-year-old Romanian Adriana Iliescu in January last year.

20 Grandchildren, 3 Great-Grandchildren

Arceli Keh, also of California, was 63 when she had a baby in 1996, and Italian Rosanna Della Corte was 63 when she gave birth in 1994.

Mr. Wulf, whose first wife was infertile, said: "I never even dared to hope that it was possible."

Janise Wulf has 10 living children, having lost one son at birth and another in his 30s.

The eight grown children range from 24 to 40, and she has 20 grandchildren and three great-grandchildren.

To avoid confusion about cross-generation relationships, the family plans to refer to all the children as "cousins."

'This Is the Last One'

Wulf's daughter, Desiree Myers, 28, who had a baby four months ago, said: "I think she's amazing. She's got more than enough love to give. I believe our only reservation was her health and coming through this. Giving birth is hard at any age, in any body, let alone at the age of 62.

"But obviously we love her and we support her, and now Ian has a little brother."

Mrs. Wulf, who was born as a premature, 3 lb. twin, was blinded by high oxygen levels in her 1940s incubator, which killed her smaller twin.

Mrs. Wulf discussed with her husband the possibility that she may not be around as the boys grow up. She added: "I think I'm a much better parent now than when I was younger. I'm not working. I'm not under stress. I'm ready to enjoy them."

But she added: "This is the last one."
