Do you pay privately for the home your daughter is in?
Goodness me, no!
Have you heard of NHS Continuing Health Care Funding (CHC Funding)? It is for people, whose needs for care stem from a primary medical condition.
So, for instance DD has a congenital brain abnormality, causing initially the complex learning difficulties and later, the epilepsy. She needs to be under adult supervision 24/7 - as while she can go to the toilet, get in the bath, eat her dinner, etc, she can have a seizure at any time. Therefore the epilepsy is the primary medical condition, and the needs for care arise from that.
I asked for her, as an adult to be assessed for CHC funding. There is a checklist, with various headings like cognition, communication, skin care, breathing, etc including seizures. Anybody who has uncontrolled epilepsy reaches the priority level of seizures, and this entitles them to CHC funding. Other people might for instance be severe in cognition, but mild in communication - they have to achieve several severe levels or whatever to reach the criteria.
NHS care is free at the point of access, and once someone is entitled to CHC funding, the CCG has to meet all their needs arising from the condition - say incontinence pads for incontinence during seizures. (You can get incontinence pads anyway from the NHS, but they tend to be rationed to say 2 a day - actually, with CHC funding, the rationing won't apply, they should get whatever they need).
We could have had carers at home, to help out with DD 24/7; but that does not work for us or DD. We found the care home, a specialist centre, where she is and the CCG funds it.
However, children with complex medical conditions can get NHS CHC funding for children. There should be something like The NHS Framework for CHC funding for Children on Google. Have a look at it, and the criteria for getting it. I would have thought you can get for DD, although I am not sure what age it goes from. Social workers might tell you "Oh, you won't get that!" Don't take any notice of them - they do not, ime actually understand the law around CHC funding.
If you haven't applied already, try applying for DLA care - its difficult to get mobility for a child under 2, as they are usually in a buggy anyway. Look at the Cerebra Guide on DLA, as its crucial to get the wording right on the form - I always put in every box "See attached" and answer the question in a Word document, with DD's name and NI number at the top of every page. Then you can copy and paste the same stuff in answer to most of the questions, because the questions are essentially very repetitive. If she gets that, then you can apply for Carers Allowance.
