They're having problems with nutrition and hygiene. They need our help its obvious, and don't want to see something really bad to happen to prove it. My MIL has dementia and FIL has mobility issues, diabetes, high blood pressure. Don't really know how to get them to give in and let us handle some responsibilities for them. Any suggestions on how to handle this. They don't eat right, she cooks in grease grease grease, and their hygiene needs addressed.
