Nadya Suleman

Octomom Nadya Suleman says she has "screwed up" her and her children's lives by not looking toward the future before having so many kids.

"I screwed up my life and I screwed up my kids' lives," Suleman said in her Fox documentary, Octomom: The Incredible Unseen Footage, which aired Wednesday. "What was I thinking? What the heck am I going to do? I have to put on a strong façade. I can't regret it now because I love them and they're here."

The 33-year-old also said it was "selfish" to have so many children without a father figure. In January, Suleman delivered octuplets, bringing her brood to 14.

The two-hour special gave viewers a peek into Suleman's chaotic life. It included a frenzied scene in which she struggles to feed and tend to her infants in bed. Suleman also shared her fears of her children being snatched, said she hasn't had sex in a decade, and spoke of her difficult relationship with her mom, Angela Suleman, who said her daughter can't "frivolously keep procreating." 

Suleman also took a jab at fellow mom-of-multiples, Kate Gosselin, who got a free tummy tuck in 2006 and has flaunted her new figure in bikinis lately. "Honestly, I'm not as attention-seeking, probably never. It's just my opinion, but some people are desperate for attention," she said.
