There are growing numbers of young children with complex life-limiting conditions as well as varying degrees of physical, sensory and cognitive limitations currently surviving birth. As a trainee art therapist, I needed to clarify exactly what art therapy actually was and how to implement it with this clientele, which initially looked the least likely of the creative therapies to be practical. This article offers an account of my journey providing art therapy to a ten year-old girl during my final year trainee placement within a children's hospice and what she contributed in terms of my development and understanding. Neurobiological studies of sufferers of trauma (who can display similar restricted sensory, emotional and cognitive processing capacity) suggest that art can function in a direct manner on the brain, enabling expression and communication. Art therapy becomes feasible with these children if their anger and frustration is seen as embodied very much like trauma as generally understood. Initial sessions concentrated on creating routines and structures without expectation of an art product even though these could be mistaken for sensory or messy play. Finally, my client engaged with art materials and was able to employ controlled gestures resulting in making marks on paper. A noticeable positive change over my client's attitude occurred. By not focussing on expectations around the marks produced in terms of art, a therapeutic relationship developed. Neurobiological studies involving these children as a specific group and art therapy are recommended. This article offers an account of providing art therapy to a ten year-old girl who has the cognitive facility of someone much younger, is registered blind, has limited fine-motor skills, and has a life-limiting degenerative neurological condition. That she could engage in any form of making art (an often assumed prerequisite of art therapy) may seem improbable. As a result, children with similar abilities are more likely to be offered sensory or messy play, as these might appear immediately more directly accessible. Nevertheless, art materials do feature in messy/sensory play, and though the end result may, indeed, present as a mess, drawing on neurological theory I reason this could still result in therapeutic value as a mode of expression/communication. Part of the initial difficulty for me involved issues around what art therapy was. Consequently, I struggled with the idea of whether what I was doing with my client was art therapy. Although, at times, I felt I was offering sensory or messy play, I was finally able to accept that I had done so in the service of art therapy. A key factor was to do with the role of the art therapist as 'container' for the client's emotions. The art therapist's role is therefore upheld as essential to defining whether it was art therapy or not. Much of the time, what took place did not necessarily emulate what I thought of as 'normative' art therapy practice. However, these sessions were necessary to build up trust, and eventually, my client constructively engaged with art materials. The results were not pictorial, but they were controlled rather than random and were accompanied by a marked change of behaviour. I concluded that art therapy specifically was possible in this situation, and affirm that this client group should not be denied the opportunity because of potentially preconceived expectations.
