Dax Shepard allows his kids to swear

Dax said on the Armchair Expert podcast: "I fully swear in front of my kids. They are allowed to swear, not with impunity, but when it's called for, and they land it, and it's in the house and not out at a restaurant, it's OK.

"My defence of it is, I just told the girls, like, 'Hey, these are noises that come out of your mouth, and you assign what they mean to you.'"

Dax also acknowledged that his kids are exposed to curse words at school.

He added: "You just don't want them to say it in front of a teacher."

Meanwhile, Kristen previously revealed that she tries to set a positive example for her kids.

The Hollywood star explained that she and her husband try to deal with their problems in the healthiest way possible, so that their children can learn from their example.

Kristen - who has been married to Dax since 2013 - told People: "We always make up in front of them if anyone gets snarky or frustrated or fights, which we all do.

"We do not have the makeup, our conflict resolution, be behind closed doors. Even if at dinner, let's say, one of us is frustrated and is a little snarky and then we go to bed. We'll apologise to each other the next morning.

"Then we will apologise and make amends to each other in front of the kids so that they can see how conflict resolution actually happens."

Despite this, Kristen and Dax initially tried to adopt a hands-off approach to parenting.

The actress told TODAY: "When we had our first child, we said we wanted to be 'second child parents,' and we made an agreement that if she wanted to do something, as long as it didn't require a trip to the hospital, she'd be allowed to do it."
