Kim Kardashian West doesn't think she could "handle" having more than four children.
The 37-year-old reality TV star already has three children - North, four, Saint, two, and three-month-old Chicago - with husband Kanye West, and already feels stretched caring for her brood, as well as finding the time to be with her spouse.
Speaking to the new issue of America's ELLE magazine, she said: "I don't think I could handle more than that.
"My time is spread really thin. And I think it's important that in all couples, the mom gives the husband as much attention as the kids."
Kim and Kanye married in 2014 after dating for two years and the 'Keeping Up With The Kardashians' star believes they have learned good habits from one another.
She said: "He's taught me to have more of an opinion.
"I've taught him to be a bit more calm and cautious. We're a good balance."
Kim - who is managed by her mother, Kris Jenner - insists she's had to work hard for her success and her mom and father, late lawyer Robert Kardashian, never spoiled her.
She said: "I was never one of those people who were handed everything from their parents.
"Even when I worked in my dad's office, I was doing side eBay jobs on my lunch break. I lived a really great life growing up, but we were taught that if we wanted to keep that up, we had to work.
"At the end of the day, if someone offered me business or fame, I'd take the business side."
And after years in the public eye, the brunette beauty doesn't worry about criticism but thinks people who cope well in the spotlight were "born" to do it.
She said: "At the beginning, I looked at people's opinions.
"Now I'm content in my life, and I don't care. The things that make me happy now are different.
"But I swear you have to be born for this. It's not for everyone. I know I can handle it."
