My mother has Alzheimer's and is 92 years old. Is there anything that would be more difficult for her to take off, or any other solution for this recent change in her behavior? There are waterproof covers on the mattress and memory foam pad and there are waterproof pads on the edges where she often sits in the morning. But it is overwhelming to have to clean her up and change her clothes and launder her sheets almost every day! Any ideas???
