Please can someone help because I really am lost.........
My Dad has dementia - not really bad but deteriorating all the time, which is as a result of him having a series of strokes.
He had another stroke just before Christmas which has resulted in a 3 week hospital stay and he is now in temporary respite to undergo intensive physio.
He is now unable to climb stairs and can walk no more than 10 steps and the physio yesterday told my Mum he is unlikely to improve. He is also now urinary incontinent.
They have a social worker who has now told my mum that they will discharge him within 2 weeks even if he is unable to walk and that she will have to arrnge for a bed to be moved downstairs and a commode 

My poor mum is inconsolable. They live in a little terraced house and a bed and commode downstairs would have to be put in the living room which leaves virtually no room for anything else. She has a few health issues herself and physically cannot empty a commode, and although my Dad can wash himself he can't get upstairs to have a bath.
My Mum also minds my DS who is 2. He is the light of her life and the only time she goes out alone is to take him to the park or the local shops. Obviously a commode downstairs is not toddler friendly and my Mum is very tearful at the thought she won't be able to mind him. Last night in a very stressful conversation with my Aunt she said she has thought of commiting suicide but my DS and DD are the only thing that stops her 
I really don't no where to start - can my mum get help with any care ? I have looked at stairlifts but the cost is way out of reach so what else can we do ? Does my Mum have to have Dad back at home ? I no she doesn't want him in a home but she also can't cope on her own.
Any advice or help is greatly appreciated as I really don't no where to turn ....
