Would love to. We've been told to stay away by mom, hospice, the VA, etc...
We have been able to get their groceries. Their lawn and snow are taken care of. Mom is able bodied enough to keep the house clean, cook, shop (can't go out now), get dad bathed, dressed, fed, cleaned up, etc.... We used to go over every Tuesday and make them dinner. They'd come to our house every Saturday evening for dinner or desert. My wife would take mom to shows while I sat with dad. Sister-in-law would come over once in a while. Son-in-law not so much, but could be asked to do things. But we've all been told to stay away. Mom is on anti-rejection meds for liver transplant (13 years ago). Dad is weak, but can still get up and walk around in the house, to the bathroom, get dressed, etc... I've seen him reach down and grab stuff off the floor. But his dementia is the main problem. He has no idea what time it is. If he ate or not. Sometimes he's fine and others he thinks his wife is his sister or his daughter or his mother. Sometimes he eats fine. Sometimes he picks up his fork and asks "What am I supposed to do with this?" So we show him, and slowly it comes back and he eats a good meal. Just takes a long time.
Hospice got involved a couple months ago when dad got pneumonia. They came to the house and evaluated the situation and mom's ability to deal with things. They'd come to the house twice a week to check dad's health, give him a bath, and talk with mom. The VA would come in and sit with him while mom went to the store, help her clean the house if she wanted. Provide adult diapers for dad. Just about anything she needed. That was really helping her cope with stuff.
However, since this virus started, about 2 weeks ago, Hospice and the VA said they'd better not come over as often since they also take care of so many other people. They don't want to risk it. Told us to stay away if at all possible.
So, we call her every day. My wife takes groceries twice a week. She calls us 2-3 times a day to talk. But she has to deal with dad getting up at 2-3am and singing Battle Hymn of the Republic, Amazing Grace, and some strange little song he used to sing when he was drunk 30 years ago. Swings his arms around like he's conducting an orchestra. Won't go back to sleep. If he doesn't stop, she goes and sleeps in the other room. We asked her to just do that anyway, but she said she would rather sleep next to him to keep an eye on him.
Anyhow, it's just very trying for her. She doesn't want him to go to a nursing home yet. But we will encourage it if her health starts to suffer.
