Her mom had six kids, but don’t expect Kim Kardashian West to follow in Kris Jenner’s footsteps. She’s loving #momlife now, but six kids would be a bit much for the busy media mogul who just welcomed her third child, daughter Chicago, two months ago.

“My home and my heart feel really full right now, in the best way,” Kardashian told Elle for the magazine’s April cover story.

With Chicago joining 4-year-old North and 2-year-old Saint, Kardashian definitely has a full plate, but like her sister Kourtney, she’s not ruling out another addition—although she tells Elle four children would be her limit. “I don’t think I could handle more than that. My time is spread really thin,” Kardashian says.

It’s true, Kardashian has her hands in a lot of things—reality TV, apps, cosmetics—and she says starting a family has made her more carefully consider projects before jumping in.

Speaking at the Create and Cultivate conference in Los Angeles last month, Kardashian opened up about how she prioritizes business ventures now that she’s not just one of the most famous women in the world, but one of the most famous moms, too.

“Having kids really forced me to take time to think about things,” she said in her keynote. “I thought, okay, if I’m going to spend time away from my kids, I’d better really love what I’m doing and really want to focus on this.”

With the addition of baby Chicago, Kim’s time has become even more precious and her schedule is even tighter, but if Kardashian does choose to give Chicago a younger sibling she may actually find it gets a little easier. A survey of 7,000 moms found moms of four are less stressed than moms of three.

Whether Kim decides to stop now or give Chicago one younger sibling, it’s great that she’s recognizing her own limits. Having as many kids as her mom did can be great, but it’s not for everyone.

Parenting coach Eirene Heidelberger, the founder of GIT Mom, previously told Motherly that for some parents, the sheer logistics of organizing a large family can be very stressful. “It takes a lot of energy, mental resources and money to raise a large family to ensure each child feels loved, special and tended to,” she said.

Kardashian obviously has the money part covered, but it’s clear she wants to be able to give each of her kids quality time with mom, and that’s pretty much the only thing she can’t buy more of.
