Most DD children today attend regular schools and regular preschools. Although schools for the disabled are being phased out in many areas, a parent might occasionally meet up with a school official who will assume that a school for the handicapped is the only way to go.
School principals have a lot of clout in determining the tone of their individual schools.
If necessary, shop for a school and a sympathetic school principal with the help of your school superintendent's office. Schools usually welcome problem-solving suggestions from an LP's parents. Bathroom modifications and, for an older child, having a computer available are VERY reasonable requests because they are cheap and easy to accomplish. A bus, double books, stepstools, and bathroom arrangements are just about all many DD children need as long as the school itself is barrier-free. These children are protected by law and most schools these days are familiar with the law, but not necessarily with the needs of LP children.
