Blac Chyna has been quite busy since giving birth to her second child Dream Kardashian – whom she had with Rob – and has been relying on Kylie Jenner to look after her son while she deals with a series of pressing matters.

A source explained how 19-year-old Kylie has been keeping Cairo happy as Chyna works things out with Rob, whom she’s having a rocky relationship with.

The insider shared with HollywoodLife.com: “Kylie can’t do any wrong where Chyna’s concerned. Kylie’s been a huge help to her by watching King and keeping him happy and satisfied as she deals with her two little babies who require so much of her attention, by the name of Dream and Rob.”

News of the ladies’ friendship comes after the famous family – consisting primarily of Kris Jenner, Kim, Khloé, and Kourtney Kardashian – decided not to invite Chyna over for Christmas dinner.

A source had recently added: “Rob’s family is over Chyna. She is not invited to Kris’ holiday party.

Rob’s family is trying to distance themselves from Chyna. They can’t stand the toxic relationship. They very much care about baby Dream though. It’s just come to the point when they think Rob is better off without being in a relationship with Chyna.”

Another insider explained: “Still, she feels salty that Kris, Kim, Khloe and Kourtney aren’t supporting her relationship with Rob Kardashian and she’s equally mad at them for excluding her from family functions.”

The pair – who has their own TV show – briefly separated earlier this month following constant fighting and arguing. However, they kissed and made up soon after and spent Christmas together.
