Halloween costumes, decorations and parties -- all these fill up our agenda until the end of October finally comes.

Like most of us, the most famous family in showbiz are keeping up with tradition with their children, too.

KIM KARDASHIAN

Kim Kardashian West is a busy working mum with her KKW makeup line launching at Ulta before Halloween. But the mom of four and husband, rapper Kanye West, took the time to bond with their kids.

The Kardashian-West children, North West (6), Saint West (3), and Chicago West (1), had a blast with their parents at Nights of the Jack in Los Angeles. Their youngest, Psalm West (5 months), was at home.

Sources revealed that the KUWTK stars were "hands-on" with their kids. "Kim was attentive to all her children and being a great mom," sources added.

The family wore Halloween makeup, with their eldest wearing face whiskers like his mom. The beauty mogul later shared their family experience on an Instagram story and captioned it: "Date night."

KYLIE JENNER

After the success of her makeup launch at Ulta, the mom of one to Stormi Webster also had a mother-daughter bonding weeks before Halloween.

The young billionaire spent time with Stormi over the weekend building a haunted house. The Kylie Skin founder, 22, shared an Instagram Story revealing the haunted house they crafted together.

Apparently, it was like a gingerbread house with lots of cookies, candy corn, frosting and spooky decorations. Jenner proudly shared that she built the edible haunted house and that her daughter decorated it.

She previously dressed up with her daughter as skeletons.

KOURTNEY KARDASHIAN

The eldest sister of the Kardashians was also the first to get ready for Halloween. The mum of three to Mason (9), Penelope (7) and Reign (4) got a pleasant surprise from their grandma Mary Jo, who put up skeletons, witches and Halloween trimmings.

Surprisingly, Kourtney's home was already in a festive mood 30 days before Halloween.

KHLOE KARDASHIAN

Meanwhile, the multi-millionaire and mum to True Thompson is taking her time to surprise her fans with a new cute snapshot of True in a Halloween costume.

True turned six months before Halloween last year, and her mom dressed her up as a Jack-O-Lantern for the event.

"My little pumpkin," Khloe shared and added that this will be an annual tradition for the mom-and-daughter.

KENDALL JENNER

The supermodel knows that she's the only one among the Kardashian sisters who is not yet a mom. Apparently, Kendall Jenner is not the least bit pressured to get settled and have children.

Jenner is a cool aunt to her nephews and nieces, often carrying them and spending time with them amid her modeling career. She also shares photos of bonding moments with the Kardashian children on social media and admits her favorite niece is Stormi.

On when she'll have her own, Jenner often shrugs it off or jokes about it. Clearly, she doesn't mind being the only Kardashian-Jenner who doesn't have kids yet.

Kendall Jenner previously had her epic birthday party on Halloween, a few days before her actual birthday, November 3. Meanwhile, everyone's keeping an eye out for the KUWTK stars Halloween costumes this year.
