My mom is 82 and has mild dementia. She can still live alone (as I live right next door to her) and get around in the house with her walker. When she wakes up, no matter what the time, she calls me. Last night it was around 11:30 pm (even though we had already said our goodnights around 9.45 pm. This morning it started at 5:15 am, then 8:26, 8:52, 10:07, etc. She always has an excuse like "I took a nap and wanted to see if my vocal chords still work". I call her every hour on the hour to keep her awake so she will sleep through the night and not get her hours backwards. She always sounds so surprised and happy when I call her, and I feel guilty when I tell her I'm still at work and need to go. Help!! Please!!!
