Kylie's daughter Stormi, 5 months, was born on February 1. Kylie welcomed her first child with boyfriend Travis Scott.
"I'm just in awe [of Kylie]," Kris told the magazine.
"Kylie is more calm than I was," she admitted when asked how Kylie is adjusting to first-time parenthood at the young age of 20. "I look at the way she loves Stormi and takes care of her. She doesn't go anywhere without her."
And Kris apparently never doubted how Khloe would fare as mom. Khloe welcomed True, 3 months, on April 12 with her boyfriend Tristan Thompson.
"I knew she would be amazing. She is always the one who has her house stocked with goodies and takes care of everyone else's kids," Kris gushed of Khloe. "They all want to have the sleepovers at Auntie KoKo's. True is the light of her life."

Photos and videos of Tristan kissing other women and bringing them into his hotel had surfaced, but Khloe has been pretty hush-hush about the situation ever since and what her plans are for her romantic relationship.
"We're focusing on baby and her life," Kris explained, suggesting the Tristan drama may not air on Keeping Up with the Kardashians. "I'm really proud of her for being an amazing mommy."
As for Kim, she and Kanye West welcomed their third child, a baby girl named Chicago, via surrogate back in January.
"Chicago is such a calm, sweet baby," noted Kris.
There's always a lot to keep up with when it comes to the Kardashian clan, but they apparently won't be slowing down any time soon.
