A 55-year-old woman acting as a surrogate for her daughter gave birth to triplets Tuesday.

Tina Cade, who already had three children, delivered the babies by Caesarean section at Bon Secours St. Mary’s Hospital.

She had carried the babies for her oldest daughter, Camille Hammond, who suffers from endometriosis, a condition affecting the lining of the uterus that makes it difficult to become pregnant.

Hammond and her husband, both doctors at Johns Hopkins University in Baltimore, had tried for four years to become pregnant.

Cade started hormone treatment last winter, and in the spring she underwent test-tube fertilization. Three embryos were implanted and all three survived.

“We didn’t plan for triplets,” Cade said recently. “I thought we would be blessed with one. It was quite a surprise.”
