She uses her walker and helps herself, but is still unsteady and I have to assist her some or change her depends underwear if it's wet - she has a weak bladder. I sleep for two hours, then she gets up and it wakes me, then I sleep another two hours before she gets up again. Usually, I'm awake at 12:30, 2:30 am and 5:30 am approximately. Then I have to get up to let in the aide who comes at 8 am. I can't afford an aide overnight as well as daytime. How does one cope with interrupted sleep? I'm tired....
