This was a choice that psychologist, Frieda Birnbaum, hopes to spread to other women. According to Birnbaum, "It's really basically about women and empowerment," she said in an interview with NBC's Today show.
"I don't feel like I went through a lot of trauma during delivery or even through the process of being pregnant," Birnbaum said.
The hospital said she was the nation's oldest mother of twins.
"Age has been redefined," Birnbaum said.
She and her husband, Ken, a New York City attorney, have been married for 38 years and have three other children — sons ages 33 and 6 and a daughter, 29.
The couple wanted another child closer in age to their youngest son, and Birnbaum's husband said it was his idea for his wife to become pregnant instead of adopting.
"I couldn't be happier about the way it worked out," Ken Birnbaum told "Today."
Their daughter has said she worries about Birnbaum taking care of the twins when they're in their teens and she's in her late 70s — concerns dismissed by Birnbaum on Thursday.
I look forward to being "empowered" with retirement, enjoying my grandkids... and perhaps even menopause by the time I'm Frieda Birnbaum's age. No comment on breastfeeding at age 60.
