"My best Mother's Day was probably my first Mother's Day, and now my second will be this day because it's my first as a grandma. And he's pretty cute," Jenner told PEOPLE last weekend while hosting a Mother's Day party at Beso and Eve in Las Vegas.
Reminded that Khloe has said she eventually wants kids too, Jenner replied: "She'd better step it up. I need another grandchild ... It kind of makes sense. I'm hoping."
Khloe, 25, who married L.A. Lakers player Lamar Odom in September, hasn't set a timeline for having children. But the other candidates for babymaking aren't looking likely right now.
Kourtney, 31, is nursing a 6-month-old. And Kim, 29, recently told PEOPLE she's not looking to start a family any time soon. "I babysat a lot in Miami, and it was really, really tough," she said. "It was good that I could babysit and give [Mason] right back."
There is one other option, but that's not ideal either. "Don't make me get pregnant again," says Jenner, 54, "because I'm a little tired."
