Although she's happy to give updates on the little one, the 20-year-old reality TV star has chose to stop posting photographs of Stormi's face on social media after she started receiving kidnap threats and nasty comments online about her baby girl.
Kylie told fans, 'She has the most ideal lips in the entire world. "She didn't get those from me, she can thank her dad for those", Kylie half-joked.
Jenner - who admitted that watching her body "go through such a change" at her young age was "physically, mentally and emotionally a challenge" - seemed to accept that certain parts of her body just won't ever be the same. My stomach isn't the same, my waist isn't the same, my butt's bigger, my thighs are bigger, like, everything.
She also talked about how Stormi has "perfect lips", opening up about her insecurity for her baby if he had of gotten Kylie's type of lips. Little Donlens, too cute, that I gave her.
She wants to get back in shape and have "real abs", people.com reported.
Answering questions in a YouTube video, Kylie said: "Stormi, she's my twin".
Kylie has always been up front about being self-conscious about her previously small lips growing up, telling Complex in 2016 of when her feelings about it started.
During an episode of her E! spin-off series, Life of Kylie, the new mom made a big confession, revealing, "I was 15 and I was insecure about my lips".
The reality TV star added, "The one thing I was insure about she has". I really wanted bigger lips. "I want to feel good". I want to make mistakes. "It's just a change, and honestly, I'm finding I have to change my style a little bit because nothing in my closet fits me from before".
