One of my coworkers makes comments every day about me being the next in the office to have a baby. Even when we are in a group meeting she randomly says in front of everyone, "So when are you having a baby?" At first I just kind of laughed it off and ignored her. Then I even tried responding with, "I'll have one after you do!" (She is older and in her mid to late 50's and already has grand children) I thought she would take the hint but her nagging has gotten worse. I've even responded with, "I'm not having a baby for a while." Then she says, "we'll what is a while? Months? A Year?" I'm afraid after I get married in 2 weeks she'll really start questioning me more than she already does. What are some good comebacks I could use to get her to stop?
