I Call Shotgun! Who Gets the Front Seat in Sibling Caregiving

Sibling partnerships, finding balance, and figuring out who’s behind the wheel.

‍

Editor’s Note from MILF & Silver Fox

‍

MILF: My brother doesn’t live around the corner, but he’s the one person who really understands the ups and downs of caring for our mom. When one of those “you will not believe what just happened” moments hits, he’s my first phone call. Somehow he always gets it before I even finish the story.

‍

Silver Fox: My sibling group text has saved us more than once. Once we started talking before things became emergencies, the pressure dropped quickly. Turns out most family problems improve with a little communication.

Sibling Road Trip! Who’s Driving?

‍

Caregiving for aging parents is rarely a solo job.

‍

About one-third of family caregivers coordinate care with siblings, sharing responsibilities like appointments, finances, and decision-making. Which sounds collaborative in theory. But in real life, “sharing the responsibility” can sometimes look like one sibling running logistics while the group chat sends supportive heart and thumbs up emojis.

‍

Family therapist Pauline Boss calls this Boundary Ambiguity.

‍

Everyone cares, but no one officially owns the job. It’s the family version of calling shotgun. Everyone wants the seat until it’s time to navigate, pay for gas, or figure out where the car is actually going. When responsibility rides around the car long enough, resentment eventually grabs the wheel.

‍

When Care Feels Uneven

‍

When responsibilities aren’t clearly defined, caregiving can start to feel lopsided.

‍

One sibling may live closer, have more schedule flexibility, or simply the one that steps in first.

‍

Over time that person becomes the default coordinator, even if no one ever officially assigned the role. That’s often where resentment sneaks in, because expectations were never spoken out loud.

‍

Psychologist Lindsay C. Gibson notes that when families experience stress, people often fall back into familiar roles they developed earlier in life.

The organized sibling organizes more.
The avoidant sibling avoids more.
The emotional sibling absorbs the tension.

Which means fairness can feel… complicated.

The GenSando Sibling Reset

‍

At GenSando, our goal is to always give tools to turn this car around. Let’s reset.

‍

Step 1: Name the Roles

‍

Someone may become:

Medical coordinator
Financial organizer
Local appointment driver
Long-distance support

Just because you all work for the same “company”, doesn’t mean everyone can do everything. When roles are named, expectations become clear.

‍

Step 2: Separate Care From Geography

‍

Often the closest sibling handles logistics. Other siblings may contribute through:

Making phone calls- From doctors appointments to weekly check in’s with Mom and Dad.
Ordering meals for delivery
Rotating visits
Being on Facetime at appointments so the one in the room doesn’t feel alone with all of the info and decision making.

Different roles. Same goal.

‍

Step 3: Start the Conversation Before the Crisis

‍

Care conversations go better when they happen before the hospital visit. Family check-ins reduce the pressure of emergency decision-making. Sometimes a simple message works.

‍

Here are some messages to send to get things off on the right track:

“Can we talk about how we want to divide this long-term?”
“Hey everyone! As we help Mom more, should we keep a quick shared note of any expenses that come up so we can split things fairly? Nothing fancy, just visibility.”
“Just flagging that things with Mom are starting to pick up. Can we do a quick check-in about how we want to share the load?”

‍

The Reframe

‍

At GenSando we believe something important about sibling caregiving: Fair isn’t always equal, but it should be visible. Everyone should know, who’s doing what,who’s contributing how, and what support looks like to all carry the load. Caregiving can last years, and we want your sibling relationships to last even longer.
