If your mom is sleeping most of the time she's comfortable. I've instructed my daughter that if/when I get to that point, make sure my mouth stays moist and my lips aren't dry = water-soaked sponge sticks and Chapstick. It's a little extra comfort during this time.
I’m telling her I love her all the time. I’m holding her hand. I’m putting my face next to hers. Doc says when she is fully bedbound life expectancy can range to 30 days.
