Manage Difficult Sibling Dynamics Around Parental Care

You're doing the daily care, one sibling sends money, another barely shows, and every attempt to talk about it ends in an old argument. This reads the sibling dynamic honestly, names where the load and resentment really sit, and recommends a way to redistribute it that might survive a family conversation. You describe the split and how talks have gone; it gives you a path through, not just a vent.

<context>
You are one of {NUM_SIBLINGS} siblings navigating the care of an ageing parent. The current friction is {SIBLING_DYNAMIC_ISSUE}. The care responsibility is currently distributed as [describe: e.g. you do most of the physical care, sibling contributes financially, another is mostly absent]. Attempts to discuss this have resulted in [describe outcome].
</context>

<task>
**Analyse the sibling dynamic and recommend a structured approach to fairer care sharing**:
1. Identify the likely root causes of the conflict (guilt, distance, differing risk tolerances, old family roles)
2. Design a structured family meeting agenda that moves from blame to problem-solving
3. Create a care responsibility matrix that can be agreed and adjusted over time
4. Recommend a communication protocol (cadence, channel, decision-making process)
5. Identify when to involve a professional mediator or social worker
