"Kanye came up with the name and Kim loved the significance behind the name. It was a mutual decision, which they discussed and agreed upon together."

Another insider explained Kanye wanted to pay homage to his hometown and his late mother, who died in 2007.

"Kim loves the nickname, and North is already calling her Chi. It's super cute," the source said.

This isn't the first member of the Kardashian-West family member to have a unique name.

A source said their son was named Saint because of Kim's highly publicized, rocky pregnancy. The insider said Saint was picked as a way of saying he is "a blessing," especially "because she had such a difficult pregnancy."

The reason why their first daughter was named North West was explained by Kim and Kanye to Kris Jenner who in turn explained it to the ladies of The View.

Kris said:

"I love the name North — I'm pro North, absolutely. The way [Kim] explained it to me was that North means highest power and she says that North is their highest point together. I thought that was very sweet."
