"[The doctor] just sat there and he's like, 'Um, there's no way to say it, but your girls are conjoined, and they're conjoined at the head,'" recalled Felicia Hogan. "And he's like, 'I have no idea if these girls are going to survive. ... You still have time to abort them.' And right then I looked at him and said, 'There's no way that's ever going to happen.'" The twins were born healthy and strong, weighing 12.5 pounds. (Courtesy Renegade Pictures)
