Maybe it's art, or music, or playing catch, or going for walks, or collecting rocks, or watching videos. The point is, as parents we often see the GOAL we want to reach, but forget that our child's special needs often can't reach the Big Goal without a lot of help and small steps. Educate his or her peers - and their parents. You may want to think about talking to some of the parents of the children in your community or school. And to the teacher, and principal, and coach, and Sunday school teacher, etc.
Many people are uncomfortable and are afraid and are simply uneducated.
Think of all these people in your child's world as a challenge - a problem to be solved, a wealth of resources to be developed. Some will never be. That's how the world, unfortunately, works. Stay away from the negatives. Don't focus on what your child can't do.
