As the drama between exesRob KardashianandBlac Chynaensues, his famous family is encouraging him to remain focused on what’s most important: his daughter.

“They always knew that Chyna wasn’t good for Rob and they’re just trying to keep him focused on his family, and not on his ex,” a source tells PEOPLE about Rob, who shares2-year-old daughter Dream Renéewith Chyna.

“They are aware of what she does, and they obviously are not happy to hear that she’s getting in fights or acting negatively,” the source adds.

“They mostly care about what’s in Dream’s best interest, and in Rob’s,” the source says.

Over the weekend, the Los Angeles Police Departmentresponded to a callabout a disturbance Chyna’s home on Sunday, a public information officer confirmed to PEOPLE.

At around 6:40 p.m., cops arrived at the mother of two’s home but did not find any evidence of a crime, the police said. Due to the lack of a crime, the police do not release the names of those who were in the home at the time of the visit.

According toTMZ, the caller alleged that Chyna was drunk and unable to care for Dream.

Chyna allegedly got into a fight with one of her makeup artists earlier that day, which may have prompted the call. TMZ also reported that along with Chyna, a nanny was home at the time.

TMZreportedthat officers arrived to prevent an additional dispute allegedly between Chyna and her makeup artist. The outlet reported the makeup artist showed up with police in order to retrieve some of her belongings from the night before.

A representative for Chyna did not immediately respond to PEOPLE’s request for comment.

They allegedly got into a physical altercation in December 2016 in the home of Rob’s younger sister,Kylie Jenner. In September 2017, Kylie, 21, and her older brothersued Chynafor battery, assault and vandalism, alleging she attempted to choke Rob with an iPhone cord during a fight.

The interviewer then asked him if Chyna’s “nails across your chest” — a reference to his accusation that she ripped his shirt in December 2016 — “felt good,” to which Rob responded: “It didn’t really occur to me that it was going to be, go into, you know, guns and strangling … I thought she was just being drunk, and you know, trying to be funny.”

When asked for clarification in the deposition, Rob added that the physical contact made during the shirt-ripping “didn’t feel good. That’s for sure.”

Chyna’s filing also revealed that Rob is seeking $500,000 in damages because of the night in question, which Chyna does not believe she should have to pay. She instead is willing to hand over $5,000 — $250 of which would be for the ripped shirt.

The year after the alleged fight, in July 2017, the exes made headlines once again because Rob posted graphic and expletive-ridden content about Chyna on social media — including three naked photos — whileaccusing her of drug use, alcohol abuse and infidelity.

Rob’s actions launched a two-month-long custody war over their daughter. The two agreed tojoint custodyin September 2017, PEOPLE confirmed — though at the time, Chyna’s lawyer Lisa Bloom said the decision “does not resolve all disputes between Chyna and Rob.”

In a statement to PEOPLE in response at the time, Chyna’s attorney said, “We are confident that we will prevail on this motion and at trial.”

A judge recentlygranted Chyna a trial datein thecase, set for Feb. 3, 2020, with pre-trial depositions of Khloé Kardashian,Kim Kardashian,Kris Jennerand Kylie to take place in the spring of 2019.
