We have meet with a great psychologist who happens to have adult children on the spectrum, so she is great. Sadly our next appointment isn't until the new year, however I think I may ring and see if they can squeeze us in somewhere.

Although the latest incident was in the school holidays I am thinking of talking to his teacher about it when we get back to school.
Just so they can alert the staff to keep a bit of an extra lookout in play times.
