Option 1

Have a direct and calm conversation with your sibling, clearly outlining your commitments and proposing a fair division of caregiving responsibilities.

Option 2

Involve another family member, such as an aunt or uncle, or a professional family mediator, to intervene and enforce a caregiving schedule.

Option 3

Reluctantly agree to take on the full caregiving role for now, hoping your sibling will eventually offer help when they see you struggling.
