Kim Kardashian is navigating parenthood largely without her ex Kanye West, a source tells PEOPLE exclusively.

On Monday, Oct. 21, a source close to the reality star, 44, tells PEOPLE that Kardashian’s life revolves around her and West’s four kids: daughters North, 11, and Chicago, 6, and sons Saint, 8, and Psalm, 5. The source notes that Kardashian is “pretty much a single mom,” as West, 47, is often “not around.”

“Kanye is sadly not around very much. She’s pretty much a single mom,” the insider tells PEOPLE. “Although she has help, it’s still a lot of work for her to balance and coordinate everything.”

The source continues, “Kim’s life is around her kids’ schedules. When they are in school, she works. When they are off, she’s very much focused on being a mom.” They add that the SKIMS co-founder “is not even dating anyone now. It’s all about work and the kids.”

A rep for West did not immediately respond to PEOPLE’s request for comment.

Kardashian is already starting to celebrate Halloween with her little ones. On Thursday, Oct. 17, she shared a clip on her Instagram Stories of a gingerbread Halloween house she had received from her sister Kourtney Kardashian Barker and her husband Travis Barker.

The tasty item featured Kardashian’s name iced onto what appeared to be white fondant on one side of the roof, as well as the names of all four of her children.

“How cute is this?” Kardashian could be heard saying as she filmed the Halloween house. “From the Barkers,” she added.

Keeping with the baking theme, Kardashian then shared a snap of fall-themed cupcakes, revealing that she had been involved in making the sweet treats.

“Baked w the kids last night,” she wrote over the photo.
