My 85 year old mom with a bad heart valve and bad arthritic knees just came home from rehab...

My brother is "In Charge?" and has had to do everything twice due to his poor follow through personality.

I am frustrated because I am a very thorough person and can see three weeks ahead....

I do not know where I fit in to this caregiver role because I had expected the task to be totally in my hands.

Now I pushed out of the way while my mom falls through the cracks...I stepped aside last time and she almost died due to poor management of her health.
I live directly next door to her and care for many animals...I can not let her fall into neglect again.

How do I approach her on this problem when she seems content to rely on a son who is less concerned with her health then control of her checkbook???
