Hi Spike,
It's impossible for us to give individual advice as is explained in
FAQ As you say you both have works pensions, I'm not sure if you'd qualify for
Carers Allowance it depends on income and whether or nor your daughter receives DLA HRC or MRC.
The best way to find out if there are benefits which could be claimed is to contact the Benefits Enquiry Line on 0800 882200.
They do not hold any case papers on the benefits your daughter currently receives, but can provide information on any additional benefits that could be paid to your daughter or yourselves.
Hope this helps.
Pat
