This mother is ready to pop! The description of the video at the time of recording says that she was "...4cm dilated, 70% effaced, numerous false alarms," and furthermore she was living on "virutally(sic) no sleep." That might explain why she'd be inclined to try an alternative method, like dancing, to induce labor!
Dancing in order to induce labor isn't exactly unheard of. The folks at Smart Mom list dancing
as a method to induce labor when other ways have failed. Last month a video
of a pregnant woman dancing to Michael Jackson's Thriller in order to induce labor went viral. Apparently this is a thing!
