"Sure you're not having twins?"
We all know it's impolite to comment on another person's size, yet propriety falls by the wayside when a baby's the reason for the weight gain. That's unfortunate, says Stacy Tessler Lindau, MD, assistant professor of obstetrics and gynecology at the University of Chicago, because surging pregnancy hormones may make moms-to-be more emotionally vulnerable to insensitive remarks. "Even though pregnancy weight is temporary, some pregnant women struggle with body-image issues."
Stop it by: Saying nothing. "By giving the commentator a silent, stunned look, she'll know you're offended," says Ingram. Should you feel the need to respond, try: "What would make you say something like that?"
