It usually starts small. You live ten minutes from Mum, so you pick up her prescriptions. Then you take her to appointments. Then you're sorting her tablets every Sunday and calling every evening. Two years later you realise you're doing almost all of it, and your brother in another city thinks things are "going fine."
Sound familiar? Caring for a parent with dementia rarely splits evenly between siblings, and it's one of the most common sources of family tension in caregiving. This guide covers why that happens and what you can do to share the load more fairly.
You're Far From Alone
Family caregiving is now part of ordinary life for a huge number of people. The Caregiving in the US 2025 report from AARP and the National Alliance for Caregiving found that 63 million Americans, around 1 in 4 adults, are providing ongoing care to someone with a health condition or disability.
Dementia care is a big part of that. The Alzheimer's Association estimates nearly 13 million Americans provide unpaid care to someone living with Alzheimer's or another dementia, and that about 59 percent of these caregivers rate their emotional stress as high or very high.
With that much care happening inside families, it's no surprise that siblings end up negotiating who does what.
Why Sibling Tension Flares Up
The Family Caregiver Alliance notes that siblings can be your best support and also a source of stress. A few patterns come up again and again.
Roles form by accident. Care often lands on whoever lives closest, has the most flexible job or was always "the responsible one." Nobody decides it. It just happens, and then it hardens.
Siblings see different pictures. The sibling who visits daily sees the bad days. The one who calls on Sundays hears a cheerful parent who rallies for a phone call. They're not lying to each other. They genuinely see different things.
Old roles resurface. Childhood patterns come back under stress: the baby of the family, the peacemaker, the one who always argued with Dad.
People grieve differently. One sibling copes by organising, another by avoiding, another by questioning every decision. Each can look like a lack of care to the others.
Money complicates things. Different incomes, different views on paying for help, and questions about the parent's finances can all add strain.
Naming these patterns out loud can take some of the heat out of them.
Hold a Family Meeting Early
Don't wait for a crisis. A planned conversation while things are relatively stable gives everyone a chance to contribute before decisions are forced.
Tips for a useful meeting:
Include your parent if they're able to take part. It's their life being discussed.
Share the same information. Send everyone the latest from the doctor beforehand so no one is arguing from a different starting point.
Have an agenda. Current needs, likely future needs, who can do what, money, and what happens in an emergency.
Use video so siblings who live far away are genuinely included.
Write down what's agreed and share it afterwards.
Bring in a neutral person if things are tense. A social worker, geriatric care manager or counsellor can help keep the conversation on track.
Plan the next one. Needs change, so a regular check-in every month or two keeps the plan current.
Our guide on what to do after a dementia diagnosis covers the practical decisions a first family meeting might tackle.
Divide Roles by Strength, Not Just Distance
Caregiving is more than hands-on help. Here are the jobs that need doing, and many of them can be done from anywhere.
Local, hands-on: visits, meals, transport to appointments, household help, respite so the main carer can take a break.
Remote, organising: managing medical appointments and paperwork, researching services, talking to insurers or Medicare, coordinating paid carers.
Remote, financial and legal: paying bills, managing accounts, working with lawyers on power of attorney and planning. Our guide to when to ask for help with money matters is useful here.
Remote, emotional: regular phone or video calls with the parent, and regular check-ins with the main carer.
Covering time: taking over for a weekend, a week of holiday leave, or a set day each month.
The aim isn't equal hours. It's a fair share that everyone agrees to and that doesn't leave one person running on empty.
Elli Cares gives the whole family one shared view. Everyone in the care circle can see the activity log, manage reminders and message each other, whether they live across town or across the country. When your brother can see how the week has actually gone, conversations about who needs to step up get a lot easier.
Support the Sibling Doing the Most
If one sibling has become the main carer, the others have a real role in keeping them well.
Ask what would help, then do it. "Let me know if you need anything" puts the work back on them. "I'm taking Mum on Saturday so you can have the day" doesn't.
Pay attention to their wellbeing. Burnout is common. Our guide on how to recover from caregiver burnout explains the signs.
Trust their judgement on day-to-day calls. Second-guessing from a distance wears people down.
Say thank you. It sounds small. It isn't.
And if you're the main carer: tell your siblings clearly what you need. Many people aren't avoiding the work, they just don't know what to pick up. Our piece on asking for help has ideas for starting that conversation.
When You Disagree
Disagreements are normal, especially about big decisions like moving a parent, bringing in paid care or driving. Some approaches that help:
Start from your parent's wishes. What did they say they wanted? What would they choose now if they could?
Separate facts from feelings. Get the doctor's view on what's safe, then talk about options.
Agree on how decisions get made. Who has power of attorney? Which decisions need everyone's agreement?
Accept you may not fully resolve old conflicts. The Family Caregiver Alliance notes that family dynamics existed before caregiving began. Focus on getting through this stage well, not on fixing everything.
If You're the Sibling Far Away
Distance doesn't mean you can't carry real weight. Take on the admin, schedule regular video calls, plan visits that give the local carer a proper break and stay informed so you're not surprised when things change. Our guide on supporting a loved one with dementia from afar goes into more detail.
Frequently Asked Questions
What do you do when siblings won't help with a parent with dementia?
Be specific about what you need, offer tasks that fit their skills and location, and consider a family meeting with a neutral facilitator. Some siblings step up once the ask is concrete.
How should siblings split caregiving for a parent?
By strength and circumstance, not just distance. Local siblings may do hands-on care, while others handle finances, paperwork, calls and planned respite.
How can a sibling who lives far away help?
Manage admin and finances, make regular calls, research services, and plan visits that give the main carer a real break.
Should we hold a family meeting about dementia care?
Yes, ideally early and then regularly. Include your parent if possible, share the same information beforehand and write down what's agreed.
A Team, Not a Martyr
The care your parent gets is better when it doesn't all rest on one person. It usually takes a few honest conversations to get there. To see how Elli helps families share the load, visit our Seniors and Families page.
