Splitting caregiving with a sibling who will not do their share

It is 9:47 on a Tuesday night. You have just finished sorting your mother's pill organizer for the week, confirmed her cardiology appointment for Thursday, and texted your brother a photo of the discharge paperwork he asked to see three weeks ago. He responds with a thumbs-up. You stare at the thumbs-up. You consider, briefly, driving to his house.

This piece is for you — the one holding the binder, the one who answers when the neurologist calls at 2 p.m. on a workday. Your sibling is not going to become a different person because you sent them a well-worded email. But something has to change, because you cannot keep doing this at the current pace and also remain a person.

Fair is a fantasy. Fair-enough is a plan.

Fair would mean a perfect 50/50, or 33/33/33, depending on how many of you there are. Fair would mean your brother, who lives fourteen minutes away, does exactly as many pharmacy runs as you do. Fair is not coming. Adult siblings do not divide caregiving evenly, and pretending they might is what keeps you awake at 1 a.m. rehearsing arguments you will never have out loud.

Fair-enough is different. Fair-enough is a written division of labor where every sibling has at least one non-negotiable job that would fall to you otherwise, and where the person doing the most physical work is compensated for it — in money, in respite time, or in the family finally shutting up about how she manages Dad's meds.

A useful heuristic: caregiving splits into three buckets — hands-on (bathing, driving to appointments, medication management), administrative (insurance, bills, legal paperwork, coordinating with doctors), and financial (paying for things, or reimbursing the sibling who does). Nobody has to do all three. But every sibling should own at least one, in writing, with their name next to it. If your brother refuses hands-on work, he can take over Medicare paperwork and the property tax bill. If he refuses paperwork, he can Venmo you $400 a month toward the housekeeper. Refusing all three buckets is not an option a functioning adult gets to select.

The conversation you have been avoiding

You have been trying to raise this for months, in oblique ways — a sighed comment about how tired you are, a pointed forward of an ER bill. It has not worked. Oblique does not work with people who have a vested interest in not understanding you.

Schedule an actual call. Not a text thread, not a family dinner where Mom is in the next room. A phone call, or a video call, with a start time and an end time. Then say, more or less, this:

"I need to talk about how we're handling Mom's care, and I need this to be a real conversation, not a five-minute thing. Right now I'm doing roughly 80% of the work and it isn't sustainable — not for me, and not for her, because I'm going to burn out. I'm not asking you to move in or quit your job. I am asking you to take ownership of two specific things: her insurance and billing paperwork, and one weekend day a month where you're the point person. If those don't work for you, I want to hear what does. But 'I'm too busy' isn't an answer I can accept anymore, because I'm also too busy."

Say it. Then stop talking. The silence after that will be uncomfortable, and the temptation to fill it by softening what you said will be enormous. Do not soften it. Let him respond.

He may get defensive. He may bring up something you did in 2007. He may cry, which is its own kind of manipulation whether he means it that way or not. Stay on the specific asks. "I hear you. What I need to know is whether you'll take the paperwork and one weekend a month, or whether we need to hire someone and split the cost."

The mental scoreboard, and why it is destroying you

Here is the part nobody warns you about. Even if your sibling agrees to more, even if they follow through, you will keep score. You will remember every appointment they missed and every text they didn't answer, and you will remember these things with the vividness of a court stenographer.

The scoreboard is not a moral failing. It is what happens when your nervous system is exhausted and someone you love is depending on you. But scorekeeping is a slow poison — it turns every family holiday into a silent audit, and it corrodes the sibling relationship you are going to need when your parent dies and you are the only two people on earth who remember the smell of the kitchen you grew up in.

Two things help. First: get the division of labor in writing, so you don't have to hold it in your head. A shared Google Doc titled something unromantic like "Mom Logistics" with columns for who does what, and dates. When the imbalance flares up again — and it will — you have a document to point at instead of a grievance to litigate.

Second: name your price and take it. If your sibling won't do hands-on work, calculate what a home aide costs in your area (in most of the U.S., expect somewhere between $28 and $40 an hour in 2024) and ask them to pay for four hours a week. If they won't pay, ask Mom or Dad, if they have the means, to pay from their own funds — this is often more appropriate than families realize, and an elder-law attorney can help you set it up cleanly, sometimes through what's called a personal care agreement. Being compensated for caregiving does not make you mercenary. It makes you solvent.

What to do when they still won't

Some siblings will read a firm, specific ask and rise to it. Some will not. If yours does not, you have fewer choices, but you still have choices: hire help and bill the parent's estate, involve a geriatric care manager (they charge $100–$250 an hour and are worth every dollar for the family meetings alone), or accept that you are doing this largely alone and stop expecting otherwise, because expectation is where the suffering lives.

What you do not do is keep pouring yourself into the gap while quietly hoping they'll notice. They will not notice. They have arranged their life around not noticing.

Tonight, before you go to bed, open a blank document and write down every caregiving task you did this week. Just the list. Tomorrow, send it to your sibling with one sentence: "Can we talk Sunday at 4 about how we divide this going forward?" Put it on the calendar before you lose your nerve.
