Let her call her attorney as much as she wants. If she wants to pay attorney fees all the time let her. The thing here is your attorney replying to everything and that is going to cost you money. If you are finding that all of the complaints are trivial I would tell my attorney not to reply to anything unless it has to do with a motion filed by the ex.
been to investigate you on any complaint made by the parent? If you are not doing anything wrong then the ex is going to be in a lot of trouble. The Texas family code has a statute in it concerning false abuse allegations. If a parent files false claims the courts deal with them severely to deter this sort of thing.
Child Support is something that is handled by the attorney general. If it has been more than 12 weeks I believe you can contact them and they will deal with it. If she is working they will automatically garnish her wages.
