My friend's son was diagnosed with autistism. One day she took another route to drive home from school due to a detour. Her son was so upset by this. Never again did she take the same route home again. She started to mix things up including his school lunch box. He would get fixated on things and she wanted to teach him change was a part of life. She gave him lots of practice to get used to this concept and he got better as he got older. He's a college graduate today with a good job.
