Kourtney Kardashian Barker loves her role as a stepmom, but it took a little more work at the beginning than she expected.

The Lemme co-founder, 46, appeared on her sister Khloé Kardashian’s podcast Khloé in Wonder Land and was asked by the Good American co-founder about her experience blending her family with husband Travis Barker’s.

Kourtney shares son Rocky Thirteen, 18 months, with Barker and is mom to three kids whom she shares with ex Scott Disick — sons Mason, 15, and Reign, 10, as well as daughter Penelope, 12. Barker is dad to son Landon, 21, daughter Alabama, 19, and his stepdaughter Atiana, 25, all of whom he shares with ex-wife Shanna Moakler.

“I love my role as stepmom because I don’t feel like it’s up to me to discipline and so we’ve kind of allowed each other to…we’ll talk about it and then he can handle the harder things,” Kourtney says of her Blink-182 drummer husband.

“I definitely give advice or try to be a good role model, or even just how they say modeling is the best way to kind of teach your kids more than just saying certain things,” she continues. “So I feel that hopefully just being a positive influence or an example, and we have lots of good conversations and we laugh. I feel like in the best way, I can be there to be supportive, or really in any way that they want me to be for as much or as little as they want.”

The mom of four goes on to say that since she had a friendship with Barker and his kids prior to being in a relationship with the musician, she assumed it would be a “seamless” transition to blending their two families.

“So I think having that history definitely helped. And I used to think too going into it, ‘Oh, we have such a good foundation that it would just be seamless,’ ” admits Kourtney. “But some days I’ve thought, ‘Wow, this is really hard, blending families.’ ”

Khloé jumps in to add that regardless of a person’s history with someone, kids will always want to know their role in a new situation and are prone to testing boundaries.

“Also, I think it was hard for all, but we moved out of our house that we had lived in for the kids’ whole lives and then moved in there, and sharing space,” Kourtney says. “Which we did slowly, we stayed I think a year and a half separately, but married, but living a block away from each other. So I think that was really a helpful transition.”

This past Mother’s Day, Kourtney received love from her husband and her own mom, as well as some of her stepkids.

“Happy Mother’s Day to someone who chose to love me like her own,” Barker’s daughter Alabama wrote on her Instagram Stories alongside a photo of Kourtney. “You stepped into my life with patience, care, and an open heart, and I’m so grateful for everything you’ve done to support and guide me.

“Your presence has brought comfort, strength, and so much love, and I truly appreciate the role you’ve played in my life,” she continued. “Thank you for showing up, for listening, and for being someone I can count on. You mean more to me than you know.”

Barker’s son Landon also shared a tribute on his Instagram Stories with a family photo, captioned: “Happy Mother’s Day @KourtneyKardash love you so much!”
