I struggle at times to show my inner child to my T. One thing I started to do was to draw pictures and write letters with my non-dominant hand. It feels easier to share the pictures but I feel comforted when I am in a session and my T and I(adult) are looking at them together. When my T does not shame me/my inner child, I begin to accept her as well. I do feel vulnerable, though and could really relate to your post!
