Sometimes mom information is more than a person can bear. While the graphic details of a c-section infection is water cooler conversation for one woman, it might make another lady's stomach turn. Depending on the parents involved, kid chatter can go from tub toys and tattling to homework issues and head lice in a matter of minutes. And that's appropriate when both parties are willing, but what happens when someone doesn't want to hear about parenthood? From between-the-sheets details of postpartum sex to a play-by-play description of water birth, how do you halt unwarranted conversations? Do you take the polite approach or get right to the point?
