Here’s a riddle…How does a mother give birth to two babies at the same time when the babies aren’t twins? The answer is something called “superfetation.” Sophie Small, who’s a 30-year-old in Great Britain, seems to have gotten pregnant with daughters Holly and Darcy four weeks apart and this mystery was NOT easy on her body. Small was hospitalized eight times in seven weeks due to the havoc superfetation wreaked on her body. She recalls, “I was carrying two babies who were growing at different stages, but we didn’t know that.”

If this story makes you worry about it happening to you, don’t. According to the Cleveland Clinic, “Superfetation is so rare in humans that there are only about 10 confirmed cases.” They added, “The chance that you’ll be affected by superfetation is close to zero.”
