Companion Care Needed For My Father In Wilmington

I'm looking for companion care for my father in his 90s. He lives in assisted living. He has experienced several recent falls due to confusion and unsteadiness on his feet, particularly in the late afternoon. We are looking for someone to serve as a watchful companion, particularly when he tries to stand/walk, and to remind him to use his walker/wheelchair. Most of the time you will just be sitting.
