On Tuesday's episode of "The Ellen Show," Kim Kardashian spoke with Ellen DeGeneres about her pregnancy with her daughter North West and her desire to have "two, three or four" children in total, E! News reports.

Kim explained that taking care of her sister Kourtney's children in addition to her own child was tough. However, because she enjoys having many siblings -- Kim revealed that she might give in and have up to four children altogether.

"Well, I just went to San Diego and to give my pregnant sister [Kourtney Kardashian] a break," Kim told DeGeneres. "I took care of my niece, nephew and my daughter. To bathe them all three, feed them, get them in the pajamas and down for bed I was literally, like, crying. It was so hard. Three kids. I don't know how my mom did it with six. So, it was really, really hard. So, I'll go for two -- but then again I have so many siblings and I love it. They're my best friends. I would want that for my kids. So I'm going to do two and see how it is."

DeGeneres then chimed in and suggested that Kim have six children like her mother.

"Maybe three or four -- I go back and forth," Kim responded.

Despite revealing her desire to grow her family with her husband Kanye West, Kim also admitted to "dreading" the idea of becoming pregnant again.

"[Pregnancy] was not a beautiful thing with me," Kim recalled. "Kourtney looks so beautiful pregnant. She has the best pregnancy style. I couldn't figure it out and I'm just dreading when I have to figure it out again." She went o to say, "I had a medically really tough, challenging pregnancy, but it is so worth it. I am so obsessed with my daughter. It's so worth it."
