A disability may form a small or a large part of a child's life as he or she develops to become an adult.
Although the language we use to describe disabilities may seem specific, in reality disabilities label a varied group of conditions. Quality of life is not the same thing as disability such that many children with disabilities enjoy good quality-of-life.
Children with cognitive disabilities often have challenges in their speech, problem-solving, memory, self-control, and other mental skills. If these disabilities are severe they may only be able to produce few if any words or signs of expression, and may have challenges understanding cues or language. Children with moderate cognitive disabilities may have challenges in daily living skills or social skills such that although they generally have some ways of communicating with language or signs, most need the supports afforded by living in a group home or with their parents as adults.
