Judges tend to have favorite child therapists that they trust. This is necessary as their are a lot of bad therapists out there who have no grasp of the reality of life.
I usually find out who the judges favorite is and hire them for opinions in divorce cases where I see a problem.
Your being cautious is wise. If necessary, use a school counselor as a third party to report problems in order to keep you in the clear.
It’s not me but I’ll pass on if appropriate the idea of using a school counselor. That might be a solution as school counselors are government employees who might be able to quell an overreaching by CPS.
