Dr. Bruce Shephard is an obstetrician in Tampa, Fla., and co-author of "The Complete Guide to Women's Health" (Penguin Press, 1997). Shephard explains that outies are the result, simply, of "individual variations in the anatomy." So the baby's delivery, the cutting, clamping and aftercare of the umbilical cord -- none of that affects the navel's final appearance? "No," Shephard says. "Cord clamping is done several inches away from the navel. [The navel's shape] has nothing to do with anything the physician does or subsequent care from the nurses."
