Despite doctors' warnings, Kim Kardashian West -- with Kanye's help -- is planning on giving three-year-old North and one-year-old Saint a new sibling. 

Kim's desire to have a third child was revealed last night in a promo clip for next Sunday's episode of Keeping Up with the Kardashians. "I'm gonna try to have one more baby," Kim says, only to be met with looks of concern from her mother and sisters. 

"I want my kids to have siblings, but the doctors don't feel like it's safe for me," she explains. Kim has been open about the struggles she's had during her first two pregnancies. She suffered with pre-eclampsia while pregnant with North, and she experienced placenta accreta during both pregnancies. She wrote about dealing with both conditions when she was pregnant with Saint. 

"I don't want you to do something that puts you in danger," Kris Jenner tells Kim at the end of the 15-second clip, which you can watch below.
