"When you have a surrogate, for me, I realized that having a baby shower for Chi was actually so much more beneficial for my kids, because they saw people come. They actually saw that it was like, 'A new baby is coming,''' she revealed.

ANOTHER KARDASHIAN BABY?

As Kim Kardashian eagerly awaits the arrival of her fourth child, another Kardashian sister may be planning a fourth pregnancy of her own.

In November 2018, Kourtney Kardashian revealed that she was taking hormones to stimulate ovulation and harvest her eggs.

Kourtney, 39, is the oldest of the Kardashian sisters and shares 3 children with ex Scott Disick, from whom she separated in 2015.

Kourtney explained that she was stimulating ovulation in order to harvest eggs for cryopreservation in case she wanted to have another child at a later date. Perhaps sister Kim will inspire Kourtney to add to the Kardashian clan.
