Drove, I appreciate what you mean by your dd 'only' having autism/gdd etc, but don't underestimate the effects it has on your lives. She may not be paraplegic, or have something like severe cerebral palsy, but it's six of one and half a dozen of another. My dd has severe autism and epilepsy, and I completely understand where the DLA goes, and why it is totally justified for us to claim it. I used to feel guilty because she got the same DLA as a child who couldn't walk, or see and hear, but in the end, her disability affects her life just as much as paraplegia or sensory loss affects others. Our children may be able to walk, but that can bring problems of it's own if they have no sense of danger, for instance.
I'm honestly scared of this government and what they are trying to do to us and praying that the changes they are proposing are illegal and can't be brought in. I can't see how it's not a human rights issue when you deny someone their basic needs.
