Momo, a person connected to my work recently asked me if i was the staff member who had recently had a baby! At 50 years of age I chose to receive it as a compliment that this lady thought I was young enough to have a baby A couple of years back someone asked if I was pregnant. I was was wearing a shapeless sack like dress on a hot day, rather than the skinny pants and blazer type outfit she was used to seeing me in.. again, I took it as a compliment... she obviously thought I was younger than I am.
Try not to let it bother you. People can be a little thoughtless but I don't believe they mean to be rude or hurtful.
You have never looked pregnant to me, just gorgeous and well dressed xxx
