To illustrate her point, the reality star decided to share a new photograph of her little girl, who turned six months on Sunday. She accompanied the picture with the touching but simple caption, "Smile."
The new snapshot shows North giggling at the camera, while chewing on a plush white blanket. Her resemblance to her famous mum is striking, with her big brown eyes staring out.
While Kim and her husband-to-be Kanye West were initially reticent to share their daughter with the world, they have been more forthcoming in posting pictures recently.
Rapper Kanye shared the very first photo of the little girl back in August when he appeared on Kris Jenner's talk show. Since then, pictures have included little North swaddled in a blanket, smiling on the sofa and, most recently, posing next to artist Jeff Koons in Miami.
Kim revealed in the Q&A that she hopes to have more children in the future. Asked where she would like to be in a decade, she responded, "In 10 years I see myself raising a family of 3 children possibly, and just (loving) life, my husband and (our) children."
