Kardashian also opened up about family planning earlier this month explaining that thepandemic interfered with her plansto have another child sooner.

“If you do need assistance in fertility, it’s much more challenging during COVID,” she said on an episode ofLady Parts with Sarah Hyland, “They say, ‘If you wanna make God laugh, tell him your plans.’ So the one time I’m actually really trying to plan, God is saying, ‘Uh uh, you can’t make your plans like this!’ "

“My plan was to have kids closer in age,” continued Khloé. “But with COVID and everything, my plan’s been a little delayed. I definitely do want more kids. I have so many brothers and sisters. I think it’s such a blessing — especially during these times — to have a family member or people that you can play with and rely on and just have a buddy through life.”
