My young adult daughters and I live with and help to support my sister. Between the 3 of us, we are her main caregivers and juggle our schedules to make sure she is always covered. Hygiene is becoming an issue, and my main concern right now is to protect ourselves from her very dirty hands touching things, especially in the kitchen. She is older than me by 12 years and a retired nurse, so (in her mind) she knows way more than me and her hands are always just washed. The truth is that she smokes, she masturbates in her room at night (we can hear her) and she has toileting issues - and I know she never washes her hands except when she does manage a shower. She refuses all help. But I'm only asking about the handwashing right now. I've tried everything except force, and I know that won't work. Even if I'm washing my hands and I suggest she do the same before she eats, she is very put out and the most she will do is run her hands under the water and wipe them on the towel I leave out for her coffee spills. We use paper towels in the kitchen and bath to cut down on spreading germs. I am afraid her lack of hygiene will make us sick. Any ideas?
