NPR: When One Sibling is Developmentally Disabled

…”Of course, there are no good terms: special needs, intellectually disabled, mentally retarded, brain damaged. The labels range from euphemistic to offensive. The best seem clinical and unemotional, as if not to burden anyone with the real difficulties behind the phrases.
But Cecily manages very well. She lives semi-independently in a community for people with developmental disabilities. She holds a full-time job caring for severely disabled people. Once a week she does what she loves best, helping in a kindergarten. She cooks and shops and watches movies on a DVD player with her nose practically touching the screen.”
