TRENTON, N.J. - A 60-year-old woman became a mother, twice over, when she delivered a pair of boys Tuesday.

Frieda Birnbaum gave birth to “Baby A” at 12:44 p.m. and “Baby B” a minute later by Caesarean section at Hackensack University Medical Center, hospital spokeswoman Nancy Radwin said. The twins each weighed 4 pounds, 11 ounces, she said.

“The mom is in recovery, and she and the babies are doing really well,” Radwin said, declining a request to speak with the mother.

Hospital officials believe Birnbaum may be the oldest woman to give birth to twins in the United States, Radwin said.

Birnbaum, a psychologist from Saddle River, underwent in-vitro fertilization last year in Cape Town, South Africa, at a center that specializes in older women. She and her husband, Ken, a New York attorney, have been married for 38 years and have three other children — sons ages 6 and 33 and a daughter, 29.

Birnbaum told Fox News she wanted her younger son to have siblings closer to his age and wanted to remove some of the stigma attached to older women giving birth.

Coincidentally, Tuesday was the birthday of twins born one year ago to a 59-year-old woman — also to a New Jersey woman. Lauren Cohen gave birth to Gregory and Giselle on May 22, 2006, at New York Presbyterian Hospital/Columbia.

Cohen said Birnbaum contacted her after seeing her name in a magazine and that the two quickly became friends.

“We talked about babies; I suggested things that would be helpful when you try to feed two babies simultaneously,” Cohen said.
