Daddy left Mom well off and her money should last around 9-10 years if nothing major occurs (new roof, car breaks down, etc.). She is spending quite a bit on caregivers, and I have the opportunity to take more time to be with my family if we hire either another caregiver for weekends and my husband doesn't believe we should be spending the money on it. My sister is in agreement with me that we spend it now, and if something major does come up, we can always stop the weekend caregiving and let me go back to doing it.
I know my sanity, health, etc are worth the price too...
