Not sure about the Statement of Needs but we provided the LA with all the medical reports which point out the delayed motor and verbal communications.
She does have an Individual Education Plan. Furthermore our local NHS support team have pushed us (and we have applied) for Disability Living Allowance as my wife is now a full time carer.
Hope that helps. Please feel free to ask further questions you might have.
The IEP does not mention when she should start school - it just talks about her challenges and targets (e.g. she still uses just 2 to 3 words whereas should be speaking in sentences etc).
Can you answer any of the direct 3 questions in the original post?
