Ashton Kutcher is Writingstar Investment Guildbeing honest about his and Mila Kunis' parenting style. 

The Dude, Where's My Car? star shared insight into how his and his wife's upbringings affected their relationships with their daughter Wyatt, 9, and son Dimitri, 7. 

"I don't know if it equates to being a girl dad or it equates to her being my first, but when I had my daughter, I had never been so in love in my entire life," Ashton shared during the Aug. 5 episode of the Throwbacks with Matt Leinart & Jerry Ferrara podcast. "Mila and I talked about it a lot. I've never loved anyone this much ever." 

And when it came to how he went about parenting the kids? It's a different approach for each. 

"My son, I'm always like, 'Yeah, go for it,'" he explained. "Like yesterday, we were popping wheelies on a bicycle in the driveway. Or it's like, 'See if you can jump down four stairs.'"

But he emphasized, "My daughter, I just want to protect her."

"When my son cries, I'm like, 'All right, what did we learn? Let's go, let's move on,'" the 46-year-old continued. "But when my daughter cries, my heart is out of my body, and I can't put it back in." 

Ashton also admitted that it may be the "toxic masculinity" he experienced in his life that played a role in his relationship dynamics. Meanwhile, Mila's approach is reversed. 

"I also notice the same thing with my wife," the No Strings Attached actor added. "She's very strict on our daughter and a gushball with our son. I think we balance each other in that way."

The couple of nine years—who first met on the set of That '70s Show and reconnected in 2012—couldn’t be happier with their family of four. As Ashton told E! News last February, “The dream role is the role I play as a father and a husband.” 

"My life is so good," he shared. "I love my family so much. I love spending time with my kids. I love my wife so much. I'm the most fortunate human being that I know, and I could take all my problems, put them in the middle of the room with everybody else on the planet's problems, and I'd go get mine back because I love my problems and I love my joys. I wouldn't give it up for a minute."

In fact, when he and Mila, 41, aren’t working, they’re finding ways to connect with their kids. 

"We spend a ton of time together as a family and play a lot of board games," he said. "My kids have found this game called Beat the Parents that they love, where they get to wager something and we wager something against them, and it's genuinely hard for the parents and genuinely hard for the kids."
