I had to chime in here. We took our 14 yr. old grandson, who is devoted to John, to one of the rad txs. last summer. I has asked Alex if he wanted to see what John was dealing with at the treatments-he already knew about the mask- I was not sure if the technicians would let him watch, but they put him in the room with them and explained the whole procedure as John was radiated. Alex felt that he was more a part of what was going on after that. I guess it depends on the personality of your child. Hang in there, Ruth. Amy
