Apply to court. Remember, you are paying the solicitor. You tell them what to do. Sure they can and should advise you. But ultimately, you need to tell solicitor that this letter writing is going nowhere. Her solicitor doesn't respond because her solicitor is taking advice form HER.... So you're wasting money on those letters and she isn't.
Change the dynamic.
Apply to court and all of a sudden she is gonna be answerable to a judge who isn't gonna be impressed with supervised visits.
By the way - why supervised visits? Well she knows that without court orders if she gave you the kid, you could keep him and refuse to hand him back. But with supervised visits you can't do that. I would advise against it anyways. But my point is she is working the system. Time for you to start working the system. Apply to court.
