Kourtney Kardashian defends co-sleeping with her children until they were 11

Kourtney Kardashian has defended her decision to sleep in the same bed as her kids, speaking out on what feels 'instinctual' as a mother.

It's safe to say Kourtney not afraid to speak her mind on The Kardashians and it looks like this extends outside of the hit reality TV show too where she opened up about raising her kids in a new interview.

Speaking on a recent podcast episode, the Poosh founder has lifted the lid on family life even further.

During an appearance on Skinny Confidential's Him & Her podcast, Kourtney revealed her eldest daughter, 12-year-old Penelope, slept in the same bed as her until the age of 11.

Meanwhile, the reality TV star said her oldest son, Mason, 14, slept in the same bed as his famous mother until the age of seven.

"Every person's different and every child is different," Kourtney revealed. "I mean, also part of it [was], at a certain time I would put him to bed in his room and then he would come in my room.

"He stopped and he was like, 'I’m done with you. I sleep in my own room'."

She then revealed: "My daughter slept with me pretty much until she was 11."

The reality star's younger son Rocky is also sleeping in his parents' bed, though he is ten months old.

As such, Kourtney is a pretty busy bee right now.

"I'm on the craziest hours right now because of our whole summer of touring, but I think one thing too is that we sleep with our baby," she continued.

"As a mother, I like to do what feels natural and instinctual to me. And that’s for me what it is. Of course, I also read all the benefits and hear all the benefits.

"I mean, it's something that mammals have been doing since time existed."

While Kourtney is happy with her sleeping arrangement, she suggested her mother, Kris Jenner, has a differing opinion.

"She doesn’t have to worry about it because it's not her baby and she's done having kids," the star said.

After welcoming Rocky into the world, Kourtney took to Instagram to heap praise on her husband Travis Barker.

"To my husband, my soulmate, my best friend, my lover, my daddy to our baby boy, my everything… I wish you the happiest birthday," she wrote.

"You make all of my dreams come true and I feel so blessed to have you by my side. I love you beyond words, forever."
