Kim Kardashian’s children are piling on the stress, leaving their already “frustrated” mom even more overwhelmed.

Spilling the beans from The Kardashians star’s ongoing tensions because of her ex-husband Kanye West’s irrational acts, a source conferred to People that Kim, who shares North, 11, nine-year-old son Saint, seven-year-old daughter Chicago and five-year-old Psalm with Kanye, is extremely concerned for her kids.

The source explained that the kids want to spend time with their father, but every time the SKIMS mogul leaves her kids in his care, she feels restless due to his controversial antics.

“When Kanye’s not around, it’s very sad for the kids. North especially asks to see him,” the insider disclosed. “But when he is around, many times it causes frustration and stress for Kim.”

The mother of four wants Kanye, who is married to Bianca Censori, to simply spend time with their kids without her having to worry about their safety.

“She can’t stand when he acts irrational. She wants the kids to spend time with him in a safe environment. She finds it ridiculous that she needs her lawyer on speed dial,” the tipster added.

For the unversed, Kim became deeply concerned for her kids after she was forced to call for an urgent custody hearing.

Earlier this week, she abruptly stopped her eldest child’s visit to her dad after the TV personality was informed that Andrew Tate and Tristan Tate would come to daughter North’s meeting place.

The controversial Tate brothers arrived in the U.S. just last month after facing sex crimes charges in Romania.
