Lately, we've been getting the newspapers for my mom to read while she is with us. Today, she became frantic when I went to collect the old ones and put them in the recycling bin. My daughter, who is autistic; can not understand her grandmother's irrational behavior; therefore it irrupted into a shouting match about the newspapers when she went to collect them. Now she is taking the papers we bought her today to read and stuffing them in between the pages of a magazine as if she is hiding them from us. She is now becoming a hoarder on top of everything else.
We let the papers pile up by the door where she could see them. Any tidying up or throwing anything out was reserved for Mom's nap times.
My particular pet peeve was Mom's obession with saving those hideous plastic grocery sacks. If we tried to throw them away she would go ballistic. It drove me crazy but she wanted to give them to the church for their book sale. Mind you, the church has one book sale each year so you can imagine how many grocery sacks we had stuffed into cupboards, below the sink and anywhere else with extra space.
I agree with one of the posters who said that the older you get, the less control you have. It's an annoyance but certainly something we can work around. My Mom has been gone 8 months now. Go with the flow, as I look back, was definitely the right way to handle it (or maybe I should say, the way that worked for us). Of course, the priority was her safety but then creature comforts followed right after that.
So don't take them away, give her more. See where she puts them without commenting. Ask or have your daughter ask from time to time to "borrow" some of the papers for store ads or homework, just don't mention it again and don't give them back. If that doesn't work, collect them when she's out of the room or in the bathroom and can't see you do it. It's a way to minimize your frustration
