My T has never been able to accommodate an extra session. I see him weekly so I am not sure if he just won’t see a client more often or if he is too booked up. He is a very good and popular T so it could just be not being able to fit me in. My Pdoc says that when we are doing hard work and stuff is coming together she would like me to see him 2x/week... so that makes me feel like extra sessions are not unreasonable to ask for. Seeing as you only see your T every other week I don’t see why you couldn’t do weekly when you needed unless their schedule is too full. I would suggest though talking to T about what benefit you hope to get out of the extra session.
