Further update
Hello again, I haven't updated before as I haven't had the head-space to do so over the last couple of weeks.
Dad finished his 2nd course of AB's and then started wandering and annoying the neighbours at night - one rang me to tell me that he was making her ill. I have had so many meetings with GP's, SW's, OT's and Mental Health Team etc that I'm rapidly losing the plot myself!
Anyhow, Social Services offered Dad a sleeping carer for a week, and he now also has a mattress sensor and door alarm - so far still intact!
My brother and I have been to look at several care homes and have found two that we think are nice for Dad - not that he will ever agree to residential care.
The night carer is working well so I spoke with a Care Navigator today to investigate costs of keeping this on as Dad is very happy at home, OMG it's so expensive about £700 per week. Dad's savings will only last about two months at that rate - with his day care the total cost is around £3,000 per month to him.
So we now have to make a horrible decision to make whether to keep Dad happy for a couple of months but knowing that really we are postponing the inevitable which I know he will never accept and will only ever go in care against his will even if it is in his best interests.
