Rob Kardashian’s parenting skills

Blac Chyna has shared a video of Rob Kardashian gently scolding her son King Cairo.

In the video, King, three – Chyna’s son with her former fiancé Tyga – can be heard saying the word "s**t", before his future stepfather Rob, 29 explains that Chyna will not be pleased.

Rob says: "You can’t say that. Don’t say that. That’s a bad word. Mommy’s going to get really mad at you."

And Chyna – who is expecting a baby with Rob – revealed that she feels "blessed" that Rob is helping her to raise King.

She captioned the clip, which was posted on her Instagram page: "I’ve had this video for a min & it cracks me up! I’ve been hesitant to post it… But Idc it’s too funny my favorite part is when Rob jumps out. look at his face. But overall I’m so happy & blessed to have Robert here willing to help teach King right from wrong (sic)."

While Chyna is happy for Rob to help her "teach" King, she recently insisted she has no problem with his younger sister Kylie Jenner – who is dating Tyga – babysitting both King and their new baby.

When asked in a Facebook Live discussion about who they would rely on to mind their tot out of Rob’s sisters Kendall or Kylie, the 28-year-old make-up artist said: "Yeah, she [Kylie] could babysit the baby and King at the same time.

"[But] I would say both."

Rob quipped: "I would choose neither of them.

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

Despite Chyna and her soon-to-be sister-in-law having a two-year-long feud after Kylie began dating the ‘Rack City’ rapper, the pair appear to have now moved on.
