Occasional Companion - For 83yr Old Mom With Dementia

Looking for someone to be a companion to my 83yr old, Christian Mother on occasion to start with. She is fully mobile but has dementia. She loves visiting, showing off things in her room, going in the backyard (if it's sunny and warm out). She watches some tv but prefers to stay busy, but will watch it with someone! (So will need to be okay with that) On occasion may need to cook for her. She is a processed and artificial sugar free, Vegan. Right now we are mainly looking for someone to stay with her if we are wanting to do things in the evening or go somewhere all day and be home late. With possibly of overnights if we go out of town.
