I have my 91 year old mom with dementia and Parkinson's and my 90 year old dad with shortness of breath and kidney failure. Up until a month ago dad could take care of mom at night keeping her covered up. It stresses him out if he thinks she is uncovered and cold. He can't sleep good with her with her legs in the air and talking. I am at my wits end cuz dad calls me to cover her up. Neither one of us is getting much sleep. Is there some kind of cover you can buy to keep them tucked in? Any advice will be appreciated.
