Kim Kardashian is feeling proud of herself for finally laying down the law with her kids.

On this week's episode of The Kardashians, the SKIMS co-founder, 44, scolds her two sons, Psalm, 5, and Saint, 9, while her family watches as her boys try to do wheelies on a Cyberquad.

“This is a cybertruck ATV,” Kardashian says as her family watches her son Psalm join big brother Saint on the back of the truck. “No doing wheelies together! Oh my goodness. Be careful. Oh my god, he’s going to do a wheelie with him on there.”

The family watches as Saint drives on the grass with his little brother, turning hard to the right so the wheels come off the ground. “It’s really not the best decision,” someone can be heard off off-camera.

"No, no, no,” Kris Jenner says. “No more! No! Sorry! K, move move move,” Kardashian says, getting up to go outside and yell at her kids.

“On the cement? Yeah, it’s not funny when we’re all going to the hospital in 30 minutes,” Jenner quips.

Kardashian then leaves the table and heads outside, yelling at her sons, “No, no, no wheelies! Especially on the cement. Hey! It’s not funny. Do not do a wheelie on the…hey! Psalm! Saint! No!”

As she catches up to her kids, the mom of four begins scolding her sons for intentionally doing something dangerous. “Hey, we’re not doing wheelies. You could fall and crack your head open," she says.

"And then there goes your whole summer. You can’t get in the water if you get stitches; you can’t do anything if you have a broken bone or any stitches," she tells Saint and Psalm, who just stare back at her. "K? I’m serious. I am serious."

In a confessional, Kardashian is asked if being a mom is the hardest job she has. In addition to Saint and Psalm, the SKIMS co-founder is mom to daughters North, 11, and Chicago, 7, with ex Kanye West.

“Oh my god. Hands down,” she responds. “Hands f——— down. Toes down, hands down. But I grew some f——— balls. Now I’m the firm one, and I’m proud of myself."
