Kim Kardashian West thinks her newborn daughter Chicago is the "best baby."
The 37-year-old reality TV star welcomed her third child into the world with her husband Kanye West last month via a surrogate and has admitted, although she looks like her siblings North, four, and Saint, two, she's the most well behaved.
Taking to her Twitter account, the 'Keeping Up With the Kardashian' star said in response to a fan question about the tiny tot: "The sweetest! Best baby! She looks a bit like North and a tiny bit like Saint but definitely her own person!"
Kim chose to have Chicago via a surrogate after doctors warned her she could die if she carried another baby following complications with her two other pregnancies.
However, that hasn't stopped the businesswoman from being a "hands-on" mother to the little one as she's been getting up in the middle of the night to feed her.
A source said recently: "Kim gets up for everything, in the middle of the night, especially in the first week. It's really important they bond with the baby. Kim's a very hands-on mom. Baby is settling in beautifully. Chi is sleeping a ton for now."
Kim announced the birth of Chicago on her app on January 15 and admitted that North and Saint were "especially thrilled" to have a new baby sister to play with.
She said: "Kanye and I are happy to announce the arrival of our healthy, beautiful baby girl.
"We are incredibly grateful to our surrogate who made our dreams come true with the greatest gift one could give and to our wonderful doctors and nurses for their special care. North and Saint are especially thrilled to welcome their baby sister."
While the couple have not given a reason for naming their daughter Chicago, a source has claimed they chose the name in tribute to the city where Kanye grew up.
Kim's sister Khloe Kardashian revealed on social media that Chicago's nickname is Chi, which is pronounced, "shy".
Khloe tweeted: "I LOOOOOOOOOOVE her name ... hey Chi (shy)"
