When I arrived at nursery this morning, I was told that DS1's 1-1 was doing work with another child. This doesn't surprise me in itself as it only confirms what I've suspected for a while that he does not get exclusive use of 'his' 1-1. The other autistic boy goes to nursery in the afternoon so I'm assuming she was doing '1-1' with an NT child. I've had concerns about other issues too - that he is not really made to feel welcome and they hardly ever fill in his home-book.
I won the appeal on the Freedom of Information Request and found out that they get significantly more funding than a nursery would usually get to provide a 1-1 support because they claim to offer a specific form of therapy to autistic children. His 1-1 is an existing staff member not someone brought in for DS1.
