I am the fulltime caregiver for my 93 year old mother. She has dementia and her attention span is short now. The trouble is finding anything that we can watch together. I have a couple Lawrence Welk tapes, but I usually leave the room when they are on. I have tried Yankee Doodle Dandy, Meet Me in St. Louis, Adventures of Robin Hood and while they have thier moments, there are slow spots. Help please, advice for movies or documentaries that are easy to understand and captivating for an elderly person and caregiver.
