PROVO, Utah — A 58-year-old Utah woman is set to give birth in a few weeks — to her granddaughter.

Julia Navarro is serving as a gestational surrogate for her daughter and son-in-law.

Lorena McKinnon says after struggling with fertility issues, she and her husband tried to find a surrogate.

After several offers fell through, the Provo woman says her mother stepped up and offered to carry the baby.

The couple says by having Navarro as a surrogate they’re saving about half the $60,000 typical cost of using a surrogate.

The baby is due in early February.

The Salt Lake Tribune reports Navarro’s doctors had said that because of her age, there was a 45 percent chance the implantation would be successful.
