Hello. My father in law has dementia. His legs are starting to give way and loosing mobility especially the left leg. Due to this he needs help getting up and putting to bed. My wife and I do the getting up and son does the bed time. He is 84 and on a morning is very aggressive and verbal getting him out of bed . He can sleep 12 + hours and more if left. What do you do . Make him get up at a set time or leave him in bed .
