In a past blog post, I talked with three daughters who have all cared for their ailing mothers. The specifics of each situation are unique but one thing the trio has in common: They have all been -- or still are -- long-distance caregivers.

For two years, Barb Silver made a monthly trek to her mother's home on the other side of the country for a five-day visit. She says that period of her life, before her mother died, is a blur because she was sleep deprived and jet lagged much of the time. Judi Kaplan spent 18 months shuttling back and forth between her home in San Francisco and her mother's Santa Monica address before recently relocating her to the Bay Area. Janice Shapiro continues to make regular visits to her frail 93-year-old mother, now in a nursing home on the East Coast.
