Blac Chyna is giving her tips for a happy blended family.

And for the model, who shares son King Cairo, 12, with ex-fiancé Tyga and daughter Dream, 8, with ex Rob Kardashian, the key to successfully co-parenting with both of her exes comes down to one major factor.

“I think the main thing is communication, and also learning your boundaries,” Chyna told Access Hollywood in an interview published March 24. “If you have your own thing going on, you won’t be so much in the other person’s business.”

“Sometimes people lose themselves and they’re so caught up in the other parent’s business to where they can’t even focus on themselves,” the 36-year-old continued. “But ultimately, focus on the kid, show respect, have boundaries and communication, and you should have a healthy coparenting life.”

The Rob & Chyna alum (real name Angela White) also urged other co-parents to clearly define their relationship—especially if they choose to end things romantically.
