It looks like Kim Kardashian might not be done having babies! The KUWTK star is on the April cover of Elle magazine where she opened up about her experience welcoming daughter Chicago via surrogate — and possibly having another child with husband Kanye West.

“My home and my heart feel really full right now, in the best way,” she told the magazine, before explaining how a fourth baby would be her max. “I don’t think I could handle more than that. My time is spread really thin. And I think it’s important that in all couples, the mom gives the husband as much attention as the kids.”

It’s not a huge surprise that Kim, 37, is hesitant to expand her family, again. Last year, she was very open about surrogacy and the challenges she encountered with the process. “I think it is so much harder to go through it this way because you are not really in control,” she recently told Entertainment Tonight at the time. “And, you know, obviously, you pick someone that you completely trust and that you have a good bond and relationship with, but it is still… knowing that I was able to carry my first two babies and not, you know, my baby now, it’s hard for me. It’s definitely a harder experience than I anticipated just in the control area.”

However, there’s no denying Kim, who also shares daughter North, 4, and son Saint, 2, with Kanye, is a great mom and she’s at the point in her life when she doesn’t care about people think about her. “At the beginning, I looked at people’s opinions,” she added. “Now I’m content in my life, and I don’t care. The things that make me happy now are different. But I swear, you have to be born for this. It’s not for everyone. I know I can handle it.”
