• Mila Kunis opened up about some of her memorable parenting moments on "Ellen's" "Mom Confessions" segment
  • She said her "biggest parenting fail" was encouraging her daughter to push back when other kids push her
  • She also advised soon-to-be moms and dads to "never negotiate" with kids because "it would go nowhere"

Ashton Kutcher was not onboard with one piece of advice his wife Mila Kunis gave their daughter.

The "Bad Moms" star, 38, recently reflected on her memorable parenting moments on "The Ellen DeGeneres Show's" "Mom Confessions" segment, which was shared on YouTube Tuesday. In the footage, Kunis revealed the "biggest parenting fail" she has had so far while raising her two kids with Kutcher: daughter Wyatt, 7, and son Dimitri, 4.

Before getting into the story, Kunis laughed as she said she knew the tale would "get me in trouble." The actress then recounted the time her daughter came to her and Kutcher and told them she'd been pushed at preschool by an unkind classmate.

Kunis explained that when Wyatt mentioned the conflict, she "instinctually" asked her daughter if she'd pushed her classmate back. However, the "Black Swan" star soon learned that her husband didn't agree with the advice she gave Wyatt.

"And my daughter's like, 'No!'" Kunis recalled. "And I was like, 'Push her back next time. You push her back, and you say, 'No, thank you,' and you walk away.' And I turned around, and I see Ashton's face, and he was like, 'No!'"

She continued, "I was like, 'Don't push 'em off of a ladder or off a swing or off of a slide, but on the ground, even Stephen? You push 'em back.' I'd say that that's a parenting fail."

In the same segment, Kunis had a warning for would-be parents. The "That '70s Show" alum insisted that "kids are like terrorists" and advised soon-to-be moms and dads to "never negotiate with them" because "it would go nowhere."

Kunis and Kutcher previously made headlines in July when they revealed their family's bathing habits during an interview on Dax Shepard and Monica Padman's podcast, "Armchair Expert."

Kunis revealed that they don't wash their children every day, with her husband adding, "If you can see the dirt on them, clean them. Otherwise, there's no point."

Shepard shared that he and his wife, Kristen Bell, used to bathe their kids every night before bed but stopped when they grew older. The "Frozen" star even said on "The View" that they wait for "the stink" to tell them when it's time to bathe their children.

Their bathing revelations sparked a discourse that had social media users and other celebrities such as Jake Gyllenhaal and Dwayne Johnson weighing in.

Kunis later addressed the uproar their comments caused when she appeared on "Ellen" last month.

"It’s so dumb," she said, adding, "We bathe our dogs. Does that make people happy?"

During the interview, Kunis sarcastically praised Johnson for showering multiple times a day. "The Rock showers, so congratulations, The Rock. You Shower," she said, before adding, "It’s COVID. Who showered in COVID? We didn’t leave the house. Who cares?"
