I didn’t say it isn’t hard, neither did I state the award was correct. What I did was correct your assertion that one diagnosis led to a particular award, which isn’t correct. As I said a diagnosis isn’t relevant. DLA doesn’t work how you think it does.
LRC is for some help during the day.
MRC for frequent help or constant supervision during the day, or supervision at night or help with dialysis.
HRC for supervision throughout the day and night, or terminal illness.
isn't aware or danger can't walk alone (will run into the road)
Isn’t relevant to the care element. Given DS’s age you can only get HRM, not low, and that is hard to prove for autism, especially for younger children. There is 2 ways, under the ‘virtually unable to walk’ criteria and the SMI rules. You aren’t eligible to be considered under the latter as you need to receive HRC.
Just because a child has high functioning autism does not mean their autism is mild, or lesser than your son’s, or that they need less care. Different maybe, but need necessarily less. I have a DC with high functioning autism who receives HRC/LRM.
