How to keep your siblings updated about a parent's health

October 9, 2026

From Centis, a free care notebook you talk to. Everything in this guide works with pen and paper too.

If you’re the sibling who lives closest, you’re probably the one at the appointments, noticing the small changes, and then telling everyone else. One call at a time, slightly differently each time.

If you’re one of the others, you hear it later, in pieces, and sometimes only when something has gone wrong.

A short written update, sent to everyone at once, helps with both. Everyone gets the same facts at the same time, in words they can read again. This guide covers what to put in one, how often to send it, and a template you can copy.

Why do updates between siblings go wrong?

They’re retold, not written. By the third phone call the details have shifted: “a bit dizzy” turns into “fine” for one sibling and “falling over” for another.
Different people hear different things. Whoever asks most gets told most. The quiet sibling finds out last.
News only travels when something happens. If updates only come with bad news, every message reads as an alarm, and silence is hard to read.
Nobody knows what’s already been said. Was the new medicine mentioned? To whom?

None of this needs anyone to be careless. It’s what happens when a family’s information lives in one person’s memory.

What should a family update include?

Facts, in the order people need them:

What happened since the last update. What you saw and what your parent said, in your words. A quiet week is worth saying too: “Nothing new, a good week.”
Appointments, and what was said. Who you saw, and what they said, as close to their words as you can manage.
Medications started, stopped or changed, with the date. The date is what someone will ask for later.
What’s coming up. The next appointment, a test, a visit.
One specific thing you need help with. “Can someone drive her to the blood test on the 20th?” is easier to say yes to than “I could use more help.”

Leave out what you think it means. “She seemed off” is a feeling. “She asked what day it was twice on Tuesday morning” is something everyone can read the same way.

A family update you can copy

One message, the same for everyone, short enough to read on a phone.

[date] — update on [Mom]
Since last time: [what happened, in your words — or "nothing new"]
Appointments: [date], [who] — [what they said]
Medications: [anything started, stopped or changed, with the date]
Coming up: [next appointment, test or visit]
Could someone: [one specific thing, with a date]

Filled in, it looks like this:

Oct 7 — update on Mom
Since last time: dizzy getting up from her chair on Oct 6, and again today. Eating well, in good spirits.
Appointments: Oct 2, Dr. Lee — wants to see her again in six weeks.
Medications: new blood pressure tablet started Sep 29.
Coming up: bloodwork before the next visit, around Nov 10.
Could someone: drive her to the bloodwork? I can’t that week.

How often should you update siblings, and where?

After every appointment, the same day if you can, while it’s fresh.
A short one each week, even when nothing changed. Once everyone knows an update comes every Sunday, silence means “nothing new” instead of “nobody told me.”
To everyone at once, in one group chat or one email thread. Side conversations are fine for talking; the update itself goes to all.
Questions in the same thread. Asked there, they get answered once, for everyone.
From notes kept in one place. A notes app or a notebook works. So does Centis, which turns what you say after a visit into dated notes and drafts the family update from them for you to read and send.

What if you don’t agree on what’s happening?

A sibling who sees your parent every day and one who visits twice a year can come away with different pictures, and both can be honest.

Share what you saw, with dates, rather than conclusions. A dated list is easier to talk about than “she’s not coping.”
Take what you can’t settle to the appointment. If the family can’t agree on what a change means, write the question down for the next visit instead of deciding it in the group chat.
Talk about care on an ordinary week. Decisions are easier to discuss when there isn’t a crisis on.
Ask what your parent wants. It’s their health and their care. Check they’re comfortable with what’s shared and with whom, and include them in the updates if they’d like to be.

What a family update is not for

A written update keeps everyone in the loop on ordinary weeks. It doesn’t replace picking up the phone when something happens, and it isn’t for emergencies: in one, call emergency services first and tell the family after.

When writing the same update is the hard part

If the update after every visit is what keeps slipping, Centis lets you say it out loud instead. You talk for thirty seconds after an appointment and it keeps dated notes in your own words. Tap Update the family and it drafts a message from those notes; you read it, change anything you like, and send it to the group yourself. It’s free, and you can use it on your own without an account.
