I had a behaviour social worker around yesterday and we talked about it and narrowed down the licking to asserting his own space. He has never been cuddly and has always been a bit standoffish. He seems to be trying to create his own untainted area around his own body (and his most special toys which he licks if anyone else touches them).

Then we had another social worker today (diff agency, but both work together). She did a kindy observation and spent some time with him. We may get a support worker to help with the school transition, so he will get used to them at kindy and they will go over to school with him when he starts.
