Andrea:
So glad to see you start a PTR. I saw your post on Somer's PTR. I am sorry to hear your daughter has had a recent setback.
I see where you say your DS has Aspberger's. We thought my son had high functioning autism and there were some rough times for him at the magic kingdom. The crowds and heat and a little disappointment about the color of the dumbo he rode on caused a melt down and we left early. Since our trip, we have found out that a grand mal seizure he had after his surgery probably caused some brain damage and that is his issue, not autism. Before we went I was very intune to the autistic families. There are others on the dis who are not wish families who have autism issues. I was lurking on some of their threads. One lady created a social story book for her son to give him some structure and advanced knowledge about what each day would look like. She had some great ideas, and it was very helpful for her son. Here is the thread link, it may help you out as well.

If you have any specific questions, please ask away. There are a lot of good, experienced people on your thread already who have a wealth of knowledge and are all very helpful.
