On each mention of her newborn son, Kim used the teddy bear emoji - with one series of photos being captioned with the bear emoji alone. Does that mean they named the baby Bear? Or Teddy? Or something else bear-related?
A source told People last week that the new parents already had a name in mind.
“They have had a name in mind, but wanted to meet the baby before they decided,” the source said, adding that North, Saint and Chicago “have met their brother,” and “North seems the most excited.”
Last week, Kim and Kanye welcomed their fourth baby via surrogate, and Kim announced the birth by simply tweeting, "He's here and he's perfect!" She also noted that he looked just like Chicago, and said in her tweets from this weekend that "he is the most calm and chill of all of my babies so far and everyone loves him so much."
