How Superfetation Works: “An Indonesian woman gave birth to a 19-lb. 2-oz. baby behemoth on Sept. 24, but that was only the second weirdest pregnancy tale of the month. The strangest belongs to Julia Grovenburg, a 31-year-old Arkansas woman who has a double pregnancy. No, not twins — Grovenburg became pregnant twice, two weeks apart. Isn’t that supposed to be impossible?
Almost. There have been only 10 recorded cases of the phenomenon, dubbed superfetation. In Grovenburg’s case, she became pregnant first with a girl (whom she has decided to name Jillian) and then two weeks later with a boy (Hudson). The babies have separate due dates — Jillian on Dec. 24, Hudson on Jan. 10. (TIME)
