Q. Not a Mother of Twins: I gave birth to a beautiful baby who is now 7 months old. A bizarre rumor went around that I actually had twins, and I adopted out the disabled child and kept the healthy baby. This is not true, as I would have definitely noticed another baby coming out of me. At first I laughed it off but after months of evil glares, outright rudeness, and weird questions, it’s no longer funny. I don’t know how to prove the nonexistence of this “other baby” and some people seem intent to believe what they want to believe. My husband is outraged and has even considered legal recourse, although we can’t trace the rumor-starter. How can I clear my name, short of posting my entire medical file on social media?
