Companion Care Needed

Hello, I am looking for a afternoon weekend caregiver for my mother, who is in her 90s and fully bedbound. I am her primary caregiver and provide hands-on care seven days a week. This includes turning/repositioning every 3-4 hours. She is fully incontinence using chuck pads, no briefs. Full incontinence requires frequent checks and changes to prevent skin breakdown. She needs total assistance with all ADLs. Looking for someone preferably who is trained in working with dementia patients. Please serious inquires only.
