What Can I Do?

Location: WA So I was brutally attacked by my now ex partner, he went to jail and is facing 3 felonies. I have a criminal no contact order the state placed against him and I am going to get my final protection order against him tomorrow for myself and my son because he also threatened to kill all his children, me and then himself (we share a child)

His mom kept texting me, calling me, trying to “check up” on my son and me and I put an end to that and blocked her. When she couldn’t reach me she called my mom. When my mom didn’t answer she called my grandmother (he definitely gave her my grandmas number)

I ended up unblocking her saying not to call me or my family, I don’t want to talk, she had a whole wall of text saying that it’s not all her sons fault for what he did to me yada yada so I blocked her again. She reached out to my mom AGAIN about seeing my son and my mom said “not tomorrow” (in her request to see him the next day) “it’s still too soon so not right now” to which she immediately freaked out in text saying she was gonna go to the police and “tell them everything” ???? And that “the police, the sheriff, and CPS are on their way” and cussed my mom out, I’m pretty sure she was drunk. Well now a week or so later she called the police saying she was concerned about my son’s safety and they came. They asked me what’s going on, I explained to them the history and they said that if they get another call they’ll know its retaliation and retaliation is common in DV cases and for me and my family members to block her number.

Should I mention this to the judge tomorrow in the final order hearing? What can I do legally? Is this enough for me to put a no contact order on her?
