I'm a full-time caregiver for my 89-year-old mom with Parkinson's. I have hired an agency to have a CNA sit with her when I'm gone for any length of time. I have been relying on her LifeAlert when I'm gone for less than an hour to run errands. The agency is suggesting she's too great of a fall risk and should have someone there 24/7. I'm not sure we can afford that. Anyone have a similar situation?
