Rob Kardashian is reportedly taking his ex-fiancee Blac Chyna back to family court after learning of her recent stroller fight at Six Flags.

According to a new report, Kardashian had been growing increasingly concerned about his daughter's well-being. After watching Blac Chyna turn one-year-old Dream's stroller into a weapon, he knew he had to take action.

Kardashian and his attorneys would be filing documents requesting a custody hearing to set up strict rules regarding what Blac Chyna is allowed to do while their child is present, TMZ revealed on April 3.

Rob Kardashian Isn't Happy

In addition to Kardashian's reported safety concerns for Dream, the outlet also said he was upset about his former partner bringing new men into their daughter's life, including Blac Chyna's latest flame, 18-year-old YBN Almighty Jay. Rob wants to have an agreement in place where neither he nor his ex is allowed to bring their significant others into their daughter's life until the relationship is at least 6-months in, TMZ explained.

Rob Kardashian Wants Child Support Payments Reduced

Kardashian is currently paying Blac Chyna $20,000 each month for child support, even if they share custody of Dream and the fact that the model/entrepreneur makes way more than he does. As TMZ explained, Kardashian feels their arrangement is "ridiculous" and "absurd" for a number of reasons, including the fact that he makes barely any money now that his Instagram account has been deleted.

TMZ was told that Kardashian was planning to go to court very soon and request a "massive reduction" in his child support payments.

Is Blac Chyna a bad mom?

“Rob doesn’t think Chyna is a good mom and [her stroller fight] is more proof. He’s afraid for Dream’s safety when she’s with Chyna,” a family insider told Radar Online on April 3. “He already contacted his lawyers about this. Rob wants full custody of Dream.”

According to the report, Kardashian doesn't approve of Blac Chyna's recent decisions and feels that with the $20,000 she's getting each month, she should have had a paid escort during her visit to Six Flags. If she had, the fight wouldn't have happened.

“He is scared that Dream is in danger when she is with Chyna if she’s getting in fights,” the insider added.
