Oh, lots of sympathy, staryeyed.
We have has similar with dd1. She is 4.3 and should have started school in september. But the LEA ummed and ahhed and procrastinated.
Then they recommended that she stay i npre-school for another year, with a view to going mainstream after that. She will not cope in mainstream.
we wanted a place in an ASD unit, but the delays meant that she could not start this year. And the places that havegone to other children, now mean that there is not a place for dd1 there at all (due to the mix of children/issues they have).
we started statementing last year. and we still have nothing to show for it.
we are now moving counties because of our LEA's ridiculous behaviour - we feel we have wasted one year already, and do not want to waste another arguing when we will in all liklihood get nowhere, leaving dd1 without the help she needs, but 2 years down the line.
Do talk to IPSEA, they are really helpful - it takes a while to get through, but they have a lot of experience.
And I would get the statementing started - the length of time it takes is ridiclous, so the sooner it's started the better.
I hope things ease up a little soon
