Rob Kardashian not keen on having Kylie & Kendall babysit his kid.

In a Facebook live video to promote their new reality show "Rob & Chyna" the soon to be father joked about not letting his sisters Kendall & Kylie babysit his unborn child. While answering fan questions sent via Facebook, the couple weighed in on a fan's question.

The fan asked who they think would do a better job at babysitting their child. While Chyna said both of them . Rob for a moment said neither before saying he would probably let Kylie babysit.

"I would say both." Chyna said with a loud laugh.

Her fiancee and brother to Kylie and Kendall thought over it and said "Okay, well I would choose neither of them" before laughing it off as a joke. He went on to add.

 No, I'm kidding. Probably Kylie. I'll probably let Kylie babysit."

 CHyna quickly added.

"She can babysit the baby and King at the same time."
