Both BIL/SIL and dh?I were considering it when MIL became ill and we were worried about not being able to afford a care home suited to her needs.
The truth is, it would have been hell on earth for MIL and she almost certainly would not have lived very long.
She is paralysed from the waist downwards from cancer and needs lifting onto the commode and into bed, which dh and I are not strong enough to do.
Our only bathroom is upstairs- stairs not wide enough to take a lift that she would fit in. So she could never have a bath.
She can manoueuvre her own wheelchair, but our hall is not big enough for the kind of wheelchair she needs so she would have to stay in the living room 24/7. In fact, she would have to stay in bed as the space is too cramped for both a bed and a hoist.
She could not get through our front door in her wheelchair so would have to be carried- she is very heavy and dh and I could not manage it on our own without the risk of dropping her; it would require specialist equipment and extra man power every time she had to go for a hospital appointment.
She would not be able to get out of the house in case of fire, even if dh or I were home.
She would never be safe in the house on her own as she has no ability to move if she falls out of the chair or out of bed.
Dh is at work all day and I have had to spend a great deal of the last few years taking our (also disabled) dd to hospital appointments. She would be left alone for hours on end with the knowledge that if anything happened nobody could come.
Under those circumstances I imagine she would have committed suicide by now. Unless dh and I had managed to kill her by dropping her first.
Instead she is in a lovely care home which has the facilities to give her the best quality of life she can have: qualified staff to help with her medical issues, equipment to get her in and out of bed, allow her to go around the home, out into the garden and even on trips to the outside world, somebody on hand for emergencies 24/7, people around to talk to.
