The 34-year-old reality star and her husband, 37, would prefer a name likely connected to Kim's late father Robert or Kanye's deceased mother Donda.
The couple, who already has 23-month-old daughter North together, is expecting its second child but insiders have dismissed speculation the new arrival will also have a directional moniker, such as South, East or Easton, reported TMZ.
They opted for North because of a power element, that it is always on top or pointing up, and other points cannot match that, a source said.
