Ira Glass explains that, like the rest of America, we at This American Life are not tired of those stories of women who have no idea they're pregnant and then—poof—one day a baby pops out. Ira and several of our producers speak with Jennifer Lyne, who found out just a few days before giving birth and even appeared on the TV show I Didn't Know I Was Pregnant. Ira also speaks with a psychiatrist named Dr. Nehama Dresner about patients who go a long time in denial about physical conditions. (8 1/2 minutes)
