I hope you will be able to care for your mother at home for your sake.Your dear mother would be fine either way with a caring daughter like you. When
you are dealing with incontinence for the wheelchair bound, there are so many factors to consider for your mother's safety and cleanliness. Also for your own health and the safety of your helpers.
You should get a consultation from a nurse. Best would be a Geriatric Care Manager who is also an RN. You need a person to come to the house, consider the factors of your mother's inability to control her feet, her weight, how the transfer should work, and to suggest good products for her skin.
If she thinks you can keep your mother at home, the consultant should work out a system and teach you and your caregivers how to care for your mother.
You could check www.caremanger.org to find a caremanager in your area. If there is no one close, you could call the Area Agency or Aging or the county aging offices or even a licensed homehealth agency. Just make sure that the person you hire for this consultation has real nursing skills to bring comfort and ease to you and your mother.
Another point to consider is whether two caregivers are enough to help you. It can be very difficult to get a person up as much as is needed. The body gets tired and accidents happen. A bedridden or wheelchair bound loved one needs to be helped to move quite often so that the skin does not get pressure sores.
All of these issues can be worked out. But you do need expert help.(in person)
