Here are some suggested organisations that offer expert advice on special needs.
My son has been on dla since he was 5, he was diagnosed with autism at age 4,hypotinia and dcd.
He is now 11 and attends a special school.
His dla runs out next month and I submitted his renewal in Oct (10 weeks now ) have had the standard we have received you forms etc and to contact in 8 weeks.
I will be phoning on Monday (thought I'd give a bit of extra time due to christmas).
Slightly worried now as last time it was 2 weeks, just wondered how long others waited for renewals to go through.
