When one sibling does it all, resentment grows and care suffers. Here is how to divide the work of caring for a parent fairly — and keep your family relationships intact.

Few things strain adult siblings like caring for a parent together. One sibling — usually the closest, often a daughter — slides into doing nearly everything, while others drift to the edges. Resentment builds on one side, guilt or defensiveness on the other, and old childhood roles come roaring back. It does not have to go this way. With honesty and structure, caregiving can be shared in a way that protects both your parent and your relationships with each other.
The biggest mistake is letting resentment build in silence until it explodes. If you are the one doing most of the caring, say so — calmly, before you are at the end of your rope: "I love caring for Mom, and I'm carrying more than I can sustain. I need us to share this." If you are a sibling at the edge, look honestly at whether you have left it all to one person, and step toward the load rather than away from it. Most imbalance grows from drift and assumption, not malice. Naming it gently is how you fix it before it curdles.
Do not let care get divided by default. Gather the siblings — by video call if you are spread out — and talk openly: What does Mom actually need? Who can realistically do what? Put it in writing. A shared care plan turns vague good intentions into clear responsibilities, and clear responsibilities are far harder to quietly let slide.
Fair does not mean identical. Siblings have different distances, finances, jobs, and family situations. Aim for equitable, not equal: each person contributing according to their real capacity. And widen what counts as helping:
Hands-on care is visible and often over-counted; coordination, money, and remote support are invisible and often under-counted. Honor all of it.
A huge, hidden part of caregiving is the mental load — the remembering, tracking, and worrying — and it tends to crush one person even when tasks are split. Lighten it by making information shared and easy. Keep a common thread or shared notes about Mom's appointments and needs. And make staying connected to your parent equally easy for everyone, not just the local sibling: when every sibling can see and reach your parent with a single tap (as with a setup like Nana Chat), the daily reassurance and connection is shared across the family instead of resting on one person. Shared access spreads the emotional load, not just the chores.
Through all the dividing and negotiating, remember whose life this is. Include your parent in decisions about their own care wherever you can. The point of sharing the work is not just fairness among siblings; it is so your parent is surrounded by their whole family, not exhausted by one member and barely seeing the rest.
This season will pass, but your sibling relationships will outlast it. Assume good intent, express appreciation often ("thank you for taking Mom Thursday" goes a long way), and address friction early instead of stockpiling grievances. Caring for a parent together, done well, can actually draw siblings closer. Done in silence and resentment, it can fracture a family for years. Choose the former, on purpose.

You cannot be there every day — but you can build a network of people who can. Here is how to create a local circle of support around an aging parent.

A long call once a week feels like the responsible thing to do. But for an aging parent, many small moments of contact do far more than one big one.
