After 14 kids and major money troubles, "Octomom" Nadya Suleman is admitting that, yes, the fertility treatments that ended in octuplets were a mistake. "Was it a mistake to have IVF after having six children already?" she was asked on NBC Dateline. "Yes, absolutely," she answered. "Was I in my lucid state of mind? I don't know at that point." Suleman, who vowed never to go on welfare after her latest eight babies were born, is now getting $2,000 a month in food stamps, and posed nude recently to raise money for her family. "I have to do what I have to do to take care of my family, and I'm not ashamed at all," she told Anderson Cooper of the nudie shoot. She told another interviewer: "I'm working as hard as I possibly can to support them."
