The momager also reveals how the mannequin challenge came about in the delivery room.
Kris Jenner is still in awe over the birth of her sixth grandchild, Dream Kardashian, a little over a week ago.
"The baby is so fabulous," she tells DuJour magazine of son Rob Kardashian and Blac Chyna's daughter.
Kris also can't help but gush over how well her son is acclimating to fatherhood. "[Rob]'s so nurturing, and he’s such a care giver and such a sweet man," she says. "It’s really been such a joy to watch him go through this."

Kris was there when Chyna was in labor, and even participated in the mannequin challenge that took place in the delivery room. "It was Chyna and her girlfriends who said, 'Let's do this,' and I thought that was such a great distraction," the 61-year-old momager recalls. "I was always so nervous in the delivery room, so I gave her a lot of credit because she was so excited and nervous but still wanted to do something to make everybody laugh!"
This will be Dream's first Christmas, and as anyone who's seen their lavish holiday cards knows, the Kardashian-Jenner family loves to go big for the holidays.
"The holidays are our big thing," Kris says. "We have a lot of traditions that we celebrate year after year and believe me…if I forget ONE thing, the kids let me know right away!”
"I love when my kids need me," she adds. "Any mom loves that!"
Rob and Chyna will inevitably start their own traditions with their daughter. Not long after the birth of Dream, a source told ET that "all is good" with the engaged couple and despite still having separate homes, the two are "doing a great job at co-parenting and staying under one roof."
