Thanks, everyone.
The battle continues, and we are increasingly of the opinion that we are going to have to move area to get dd1 into a school that will suit her.
the head of the unit is saying that dd1's needs are too sensory based for the unit, and cannot be accommodated. She is basing this on the observations from her pre-school visit, where dd1 does, in fact play with the sensory things on offer (shaving foam, water/sand etc). She never does these things, or asks to do them with me at home (have offered several times, and she wanders off to read a book!)
Dh & I recken she is playing with them (we are at the water play as she is nrmally water phobic) because she has been trained to do so, literally. Her helper last year spent a lot of time gettingher to paint/get messy play with sand etc, and it is a good thing that she now does so. But in all that time, she was led away from books/letters/numbers to do so (as she was not communicating with anyone when she was reading), and she got strong positive reactions for playing with the sensory toys (and still does), so that is now what she heads for, as she craves social praise. She is rarely given the opportunity to show off her skills as they concentrate on the more basic (and important) foundations like sensory play.
Now that she is cooperating with that, she is being penalised for it, and we are told that as her play is so sensory based, she should got to the special school where their learning is sensory based.
we have meantime been to see a private special school which is aimed at language delays and disorders. She went straight in (with dh & I there too), sat in the circle at story time, and interacted well - paid attention to the story, got very excited at naming the animals as each page was turned and commenting appropriately on the story(, her keeping quiet and still skills need attention, obviously ) and helped create the days' timeline of activities. She had never been in the place before. she then sat around the table for the activity (planting herbs), and while her interaction was less (I was not sat beside her) she still sat there, and participated willingly, although needing lots of prompts.
dh & I then left ehr there for an hour or so (didn't think before we went that we would be able to), and (understandably, I think) although she was ok-ih with that, her communication really nose-dived.
The school are happy to take her for this nursery year (and are good - lots of SALT, OT and SIT goes on) and she could start as soon as we can move, but they are not committing as to whether she will progress to the school. They do not take challenging behaviour of any sort, and are a little worried by her ASD label, although they do have a number of ASD children in the school. Their position is that it is a week by week assessment of whether she is able to transfer to the school.
dh & I are minded to make this move, as the intensive approach she will get there will benefit ehr whatever else happens....
