You value your relationship with your son and how CPS can interfere with that? Pursue stability, and definitely remain med compliant. Do not give anyone ammunition that can be used against you no matter how unfair it may seem to be to you. I have avoided many disasters approaching similar problems in this way.

Be a pragmatist. Just do what you know you need to do to protect what is important to you. It being not fair or "unreasonable" or difficult or "impossible" is irrelevant.

Still, at this point, I think that you may have more immediate concerns. You are worrying about something that may never happen. So right now I would not lose any sleep over this concern of yours. You are just giving yourself more stress.
