Of course not, but apparently it's perfectly acceptable and quite usual for adults.
DH is soon to be discharged from hospital. He is completely immobile and dependent on others to get onto the bed pan and clean up.
I'm talking to people about other options, but the hospital's plan is for carers 4 times a day and in between times, he sits in his own waste (he'll have a pad so that's ok!) until carers arrive to clean him up. I will be working, but even when I'm at home I can't move or clean him on my own (they've told me this, I haven't tried, as he's still in hospital).
Now taking DH out of this because I'm in the fortunate position that I can probably arrange something else, how can this possibly be acceptable?
