Kim Kardashian revealed her disappointment with her ex-husband Kanye West after he once again shared their parenting issues on social media.

The 46-year-old rapper took to Instagram to ask Kardashian to transfer their four children from Sierra Canyon, an exclusive elementary school where they presently attend.

Kanye characterized the school as “fake” in his post and indicated it was used by “the system.”

Kim’s sources told TMZ that she is frustrated by West’s ongoing public attacks and naming of the school, which creates safety and security worries for their children.

She is also reportedly irritated by West’s claims to their children that attending school is unnecessary.

The estranged couple, who have four children – North, Saint, Chicago, and Psalm – are at disagreement over their children’s schooling.

According to sources close to the model, she enrolled her children in Sierra Canyon because of its stellar reputation as a “fantastic school” and her desire for regularity in their lives.

However, West has protested the school, citing unaccredited professors and his own unaccredited Donda school as alternatives.
