This is both sad, and shocking to me.
I truly assumed that double incontinency was almost a 'given' both in residential homes and CH's accepting those with dementia.
I really feel for you
@Lellyhelly as my Mum was also affected hugely by urinary and then bowel incontinence. She hid evidence, blamed all and sundry, and up until fairly recently would remove pads and attempt to 'wash them out' in her bathroom. She was disgusted with herself and said she was dirty and her whole demeanour and behaviour was affected. It made her really upset and despondent.
Her CH (which is mixed residential and dementia) has coped wonderfully with all of this. Their quiet and matter of fact attitude has helped Mum. They have accepted the many, many accidents and are going so far as to replace Mum's carpet with non slip laminate as her incontinence 'accidents' and food calamities are frequent and this will be a better, more pleasant and more hygienic alternative. Wiping her hands on walls, clothes, furnishings etc has just been dealt with. When I have apologised, the answer has always been 'That's our job and what we are here for'.
As
@canary states - not all CH's are the same.
It's a sad fact, but as my Mum has deteriorated, so her awareness of her incontinence has decreased significantly. I hope that you can achieve a solution so that your Mum is not so distressed.
