Prayers for Maria and Jeff as well for you & Greg.
My Grandma suffers from some kind of dementia (my Mom's Mom), my Uncle and my parent's and I were taking turns caring for her after my Grandpa passed away (almost 6 years ago, it will be 6 years in February) but she got away in the wee hours of morning on my Uncle's watch so she has had to be put into an Assisted Living and just recently was moved to the Memory Support Unit (AKA the Alzheimer's unit).
