The Keeping Up With The Kardashian’s star said she ‘could do two more,’ but she wasn’t sure she wanted to 'go through IVF' again.
She also worried about having more babies later in life.
'I'm going to turn 40,' she said. 'I don't want to be an old mom. I think four is good.'
The budding law student also said she was worried about not having enough time or energy to deal with a bigger brood, telling Laura: 'I want to pay attention. I think everyone needs attention.'
Kim then went on to praise her own mother, Kris Jenner for continuing to look after her children and grandchildren.
'Just seeing how my mom is 65, 64 and we still don’t stop bugging her.
'Like, at 40, I call her on the daily, you know all day long,' Kim continued.
Kim is married to Kanye West and the couple share North, six, Saint, four, Chicago, two, and Psalm, nine months.
