Kylie Jenner Wants a Baby by 25, Because ’30 is Too Late!’

Kylie Jenner is racing against her biological clock!

While her brother, Rob Kardashianis dating her boyfriend Tyga’s baby mama, Blac Chyna, Jenner is thinking about starting her own brood. In a clip from this Sunday’s episode of Keeping Up With the Kardashians, the 18-year-old poses an important question to her dad, Caitlyn Jenner.

"What do you feel like is a good age to have kids?" she asks (with Tyga right next to her!).

Kylie thinks that 25 is just fine. Caitlyn, 66 — who became a parent for the first time at 29 and now has six kids — advises her to aim for 30.

"I feel like 30 is too late!" Kylie responds, adding that "every psychic said that I’m only going to have two kids."

"When you have one, you might as well have two," Caitlyn says. "You want your kids close together. That’s why we had you!"

Caitlyn notes that she wants at least 30 grandkids, and tells Kylie that she should have at least three children to reach that goal.

The Jenners aren’t the only ones thinking about the future. On Wednesday’s episode of Kocktails with Khloé, Tyga, 26, told his girl’s older sister that he wants to marry Kylie one day.

Watch E!’s Keeping Up With the Kardashians on Sundays at 9 p.m. EST.
