The Keeping Up With The Kardashians star, 33, gave birth to her first child in June 2013 and revealed today that she can't believe how time is flying.
"Everyone tells you how fast it happens and how big they get so fast but you really don't understand what anyone means until you're going through it," she said on America's Today show.
"A picture of her one month ago looks so different than now. She's so good and getting so big."
Kim was asked whether North takes after her own personality or that of rapper father Kanye West.
"I would say she definitely isn't shy like her dad but if you ask her to do anything on command like clap or walk she shuts down, she doesn't want to perform. She's really sweet.
"She's a momma's girl right now. That's the phase she's going through."
Of course, the reality star was quizzed on whether she and Kanye have started thinking about baby number two...
"I grew up with siblings so if I could snap my fingers and have four I'd have four," said Kim, "but I do realise I'd have to through pregnancy again and I had a difficult pregnancy. Of course I want another child - I'd love two more.
"We'll see. I'll have one more and see what it's like."
Kim arrived in New York with baby daughter North, one, yesterday, after the pair had been to watch Kanye performing his latest concert date.
