Don't tell Kim Kardashian that as a working mother she can't have it all.

The reality star, 33, told CNBC Monday that her mother, Kris Jenner, showed the girls - Kim, Kourtney and Khloe - that they could have a career, even with kids.

"My mom taught us girls that we could have it all," Kim Kardashian said. "She works hard, she taught us that if you work hard, it's just all about prioritizing. I think that, yeah, it could get tough if you have a baby. There were so many times, I just didn't want to get up and work on something. I just wanted to be home with my baby."

She continued, "But for me and I think I can speak for my sisters, it makes us feel good when we are out working and we can provide something for our friends and products that we can't find, that we really want and it just makes you feel productive. If anyone really feels like they can't do it all, I feel like it's a little bit discouraging to say that. Even if I couldn't and it wasn't possible, I would try. I would try my best to do it all."

Kourtney Kardashian, 35, chimed in to agree with her sister.

"I think my biggest struggle as a mom has been balancing the two," she said of working and motherhood. "I do think it's possible, I just think you feel guilty ... I used to feel so guilty every time I left."

Finally, Khloe Kardashian, 30, added that each family and each mother balances their career in different ways.

"There's no cookie-cutter way; it's whatever works for your life and your career and your family," she said. "No two families are the same."
