A 58-year-old woman in Utah, the United States, is set to give birth in a few weeks, to her first grandchild.
Julia Navarro is serving as a gestational surrogate for her daughter and son-in-law after the couple struggled with fertility problems.
After several unsuccessful pregnancies, the couple began looking for a surrogate. McKinnon's friend and sister both considered carrying her baby, but ultimately decided against it.
That's when her mother offered to step in.
Because of Navarro's age, doctors had warned there was only a 45 percent chance the embryo implantation would be successful.
But the procedure was a success, and she has had a smooth pregnancy carrying a developing baby girl.
As with other surrogacy arrangements, the couple and Navarro needed three months of counseling.
The psychologists wanted them to make sure they were mentally prepared.
Mostly, surrogacy contracts are with people who are strangers to the would-be parents. It's unclear how rare it is for a woman to carry her own grandchild, but recent news reports have detailed several similar relationships in the U.S.
The baby girl is due in early February.
