Mother is 98, advanced alzheimers, lives at home with me and my husband. She can't understand time. We have tried to schedule our meals at around 8 am, noon and 5 pm. She is good about breakfast, between 8 & 8:30. Then she out again around 10 wanting to eat, we give her coffee and cookies. Lunch at 12 or so. But about 2:30 - 3:00 she's out wanting supper, not a snack she wants a full meal. This will continue every 10 - 15 minutes. Until one of us becomes irritated. She sometimes becomes threatening. Mother goes to bed after supper and eating early throws her off. She eats well. We like to have a cooked supper.
