I think it very much depends on the nature of the therapy and what is needed at different stages. I suspect in the early days of therapy, a t might make allowances for all kinds of things. There's a fine line between making allowances and enabling, though. What may be appropriate early on, when the client has limited adaptive skills may be inappropriate after the client does have those skills. The client might be expected to use those skills and to practice them in therapy. That may seem as though the t is not making allowances, but you could also see it as an opportunity to use unfamiliar tools in a safe place.
