Octuplets' mom, grandmother battle it out on video

"When you already have six beautiful children.....how could you do this?" Nadya Suleman's mom, Angela Suleman, asks her daughter during the exchange.

Her daughter cuts in the middle of her sentence to say:

"You need to learn to let go." She at one point tells her mother she is "inflexible" and needs to "stop stagnating and being fixated."

Angela Suleman stresses to her daughter that the embryos were "frozen and you didn't have to do anything."

Nadya Suleman responds:

"The only thing you can do with embryos is you can use them or destroy them."

"You want to know how they destroy them?" Nadya Suleman continues. "They allow the cells to live and then they kill them."

She goes on to add: "I wouldn't have destroyed those embryos."

Her mother expresses concern about Nadya's ability to care for so many children - they total 14. She tells her daughter she could have given them up for adoption.

But Nadya rejects that idea: "I couldn't even fathom the idea of my own children out in the world ... and not know them," she says.

Of the newborns, the grandmother adds, she felt "sorry for them."

Nadya replies that there is no reason to feel sorry for the babies, who are "healthy and thriving."

On Tuesday's "Today" show, Radar.com senior executive editor Chris Myers was asked if his Web site paid the Sulemans to appear on camera. Myers responded, "We did not pay for the interview."

Nadya Suleman told NBC's Ann Curry on earlier this month that she had six embryos implanted, two of which resulted in twins. NBC has reported that while it hasn't been revealed which doctor implanted embryos at once, the octuplets' birth has sparked an ethical debate in the medical community.

Guidelines of the American Society of Reproductive Medicine indicated that a woman of Suleman's age should have no more than two embryos implanted.
