Seeking Part-time Senior Care Provider In Phoenix

About who needs care: My grandma has molecular degeneration so she is legally blind, although still has a bit of her peripheral vision. She is still mobile, but very Shakey when standing(due to lack of activity in my opinion). I work 7:30am-5 p.m. so she needs help with her breakfast and dinner. I feel she should be put on a regimen of activity that'll help encourage her to get up from her seat and move around to help with her circulation. Her feet are hyper sensitive to swelling because as of now she sits and watches/listens to the TV a majority of the day due to her vision issue. I was curious if there could be two 3hrs shifts, one in the later afternoon for dinner too. I have only been able to find 4 shift minimum for these types of services. About the care needs: There is some doggos at my residence. They can be a bit yappy but no harm. Figured I should mention that. Thank you. Services needed include: feeding, and bathing / dressing.
