Khloe Kardashian shared on Wednesday that her 2-year-old niece, North West, is getting along just fine with her baby brother, Saint. Kim Kardashian gave birth to Saint on Dec. 5.

"North is obsessed with him," Khloe told Good Morning America. "North will say, 'My name is Saint.' She wants her name to be Saint now too."

Last week, Kim Instagrammed a photo of her two kids holding hands, writing, "She said, 'He's my best friend.'"

Although we have yet to see a picture of Saint's face, Khloe already gushed that the newest member of the Kardashian clan is "so cute and so perfect" during a live stream on her app last month.

"But I don't know, that's what everyone says, he's just so perfect," she added. "I love him."

Earlier this month, a source close to Kim told ET that Saint is definitely Kim's last pregnancy. Doctors have informed the 35-year-old reality star that it's too risky for her to conceive again, the source says.

However, adoption is still an option.

"The two pregnancies did so much damage to her body, it's just not worth it," the source says. "If she wanted more, adoption wouldn't be out of the question."
