CLEVELAND -- An Ohio woman who gave birth to her own triplet granddaughters said she is feeling fine one month later.

Fifty-six-year-old Jaci Dalenberg, of Wooster, had to be closely monitored because of her age.

Dalenberg said Tuesday on ABC's "Good Morning America" that she was happy to serve as a surrogate to help her daughter.

The girls -- Elizabeth, Gabriella and Carmina -- were delivered by Caesarean section on Oct. 11. They were more than two months premature, and each weighed less than 3 pounds.

Daughter Kim Coseno said the babies are doing well.

The Cleveland Clinic said Dalenberg offered herself as a surrogate when Kim Coseno and her husband, Joe, were waiting to adopt.

The couple used in vitro fertilization, and embryos were implanted in Dalenberg's uterus.
