I feel for you, Nate. My mother-in-law, in her late stages of dementia, had a tendency to be quite active in the middle of the night. We would wake the next morning to find the waste basket in her bedroom filled with ripped up family photos. It was heart-breaking for my husband to sift through remains, question his mother about them, and then listen to her state that he would have no use for them. We were also accused of stealing from her. She would wheel around the house with her handbag draped on her walker. It never left her side. Then came the accusations we were trying to kill her. Just a sad deal all the way around. I hope that your mom has medical power of attorney of her mother in order. At this late stage of her illness, you pretty much need to take over every facet of her well being. Prayers to your and your family.
