My father has a very poor appetite and his he gets confused about the time of day. Today he went back to bed at 1:30pm after only being awake 5 hours. Now it is close to dinner time and I don't know if I should let him sleep or try to wake him. If I wake him he is very resistant to getting out of bed sometimes. He is 94 with dementia and I don't know how much I should push him. I worry that he is not getting enough to eat.
