Woman gives birth to own grandson

A woman has given birth to her own grandson after acting as a surrogate mother for her daughter.

Linda Sirois, 49, of Maine in the United States gave birth to baby Madden earlier this month, reports the Daily Mail.

Mrs Sirois’ daughter, Angel Herbert, 25, has a heart condition which means pregnancy is unsafe. And her egg, fertilized with her husband Brian’s sperm was successfully implanted.

"It was all pretty simple as far as I was concerned,” Mrs Sirois told the Portland Press Herald.

After a doctor told her pregnancy could not be 100 per cent safe with her heart condition, Mrs Herbert turned to her mother.

“It was pretty disappointing and we were pretty upset about it,” said Mrs Hebert.

“But we kind of had an idea that it was a possibility and, all along, my mother was saying, 'I'm here and I can carry for you.' I guess we didn't really take her seriously.

“I called her last summer and I'm like, 'So, you know that offer you've been offering? Is that offer still on the table?”

Most of the fertility clinics in the area turned Mrs Sirois down before the Reprodcutive Science Center in Lexington, Massachusetts accepted her on stringent conditions.

Mrs Sirois became pregnant during the first round of IVF treatment and there were no complications with the birth, her third.

“I didn't have any young children around - my youngest are in college - so that made it easier,” Mrs Sirois added.

"I had so many well wishes and encouragement, even strangers in the community," said Mrs Sirois.

"I just saw it as I was babysitting for a few months.

"It was their child all along. It was just a room for rent."
