The Autism Education Trust has a Transitions Toolkit which although written for teaching staff seems to provide some useful tips on dealing with transition periods. It would also be useful to direct staff to if you feel they are not doing enough to help your child. Here's the link. They also have some resources which you may be able to use at home, here.
There is also some advice on the National Autistic Society website, here.
Aberdeenshire Council do have a transition programme for children who staff feel may benefit from extra help. As far as I'm aware this programme is still running.
I will look into working on some resources of my own - star charts, emotions fans, timetables and mini award notes, etc., and upload them soon. Any ideas to add to this, just let me know.
If you are a member of a group like The National Autistic Society which provides you with a member ship card or have other proof of your child's disability then you may be able to get free entry to places.
Yesterday, I used my membership card and got into Landmark (Carrbridge) for nothing. Many places don't advertise this concession and I was told that they had problems with people asking for free entry but not being able to provide proof and then complaining! So if you have the proof then ask - you might not get anything but it's certainly worth trying!!
