For mums who do the maths
You held the coats at the trampoline park. You stopped drinking an hour before the gym class. You checked the mirror on the way out. Again.
If you recognise even one of these, keep reading. Because you have probably never said any of it out loud. Not to your partner. Not to the mums at the school gate. Maybe not even to yourself.
The part nobody warned you about
A small leak. A lot of quiet maths.
A little leak when you sneeze. When you laugh too hard at the pub. When you lift the buggy into the boot. Small enough to hide. Big enough that you have quietly started planning your life around it.
Nobody warned you about this part of motherhood. And nobody talks about it, which is why you think you are the only one. You are not: around one in three women deals with bladder leaks in the months and years after having children. In your NCT group, at every soft play, in every school playground, they are there, doing the same silent maths you are.
That liner you wear just in case? It was never made for this. It says so on the packet.
1. It says it right there: for a few drops
Most of us solve it the same way. A thin liner, every day, just in case. Upgraded to a proper pad on the days you know you will be active.
Now look at the back of almost any packet. Liners are described as suitable for light discharge and a few drops. That is what the makers themselves say it is for.
Why that difference matters so much:
A liner is built for discharge. A couple of millilitres, released slowly. The filling is a thin layer of material that soaks up moisture like a sponge and then holds on to it.
A leak when you sneeze, laugh or lift the buggy arrives very differently. All at once, far more of it, under pressure. The sponge can't take it in fast enough, so the liquid sits on the surface. Against your skin.
That's why it feels damp an hour later. That's why it bunches and shifts out of place at exactly the moment you need it.
What this means:
You have been solving a sudden, under-pressure leak with a product built for a couple of millilitres released slowly. It was never a fair fight. And it was never down to you.
2. And daily use isn't recommended
It isn't just that it doesn't do what you need. Wearing one every day is something specialists actively advise against.
More and more gynaecologists warn that wearing a liner or pad every day upsets your natural balance. With itching, infections and odour as possible consequences.
Why that happens:
Your body keeps itself clean with good bacteria. Those only do well when air can get in. Wearing something sealed all day makes the perfect home for the wrong bacteria and for thrush: warm, damp, closed in.
The advice you rarely hear: never wear a liner for longer than four to six hours at a stretch. Longer than that can disturb the balance and raise your risk of a urine infection.
Do the maths:
Four to six hours. Now count your own day. School run, work, pickup, dinner, bath time. When exactly were you supposed to change it?
3. So that irritation is coming from somewhere
Many liners, pads and towels are made from synthetic materials containing plastic, fragrance, chlorine and dyes. Plenty of women end up with irritation, allergic reactions, itching or a burning feeling as a result.
Three causes, stacking on top of each other:
The greenhouse effect. Sealed, synthetic layers let no air through. Moisture and heat sit against the skin. Skin that stays wet for hours softens and damages more easily. Same principle as a plaster you leave on too long.
Fragrance and bleach. Perfume covers up smell, but it also irritates the thinnest skin on your body. With daily contact that can grow into a skin reaction that builds up over months. Which is exactly why almost nobody links it to what's sitting in their underwear.
Friction. Liners and pads shift or fold over during a day of walking, sitting, lifting and chasing. The edges can dig into the skin, especially in warm weather or during exercise.
And then the vicious circle:
Irritated skin can't recover while the irritant comes back every day. So you get more discharge. So you wear a liner more often. So the irritant returns more often. Almost nobody spots that the remedy is keeping the problem going.
4. And then the part nobody talks about
The three points above you can look up. This one appears in no product comparison anywhere. And it weighs more than all of them together.
It is the maths. The constant, silent maths.
Trampoline party invitation: can I get away with holding the coats again? Gym class booked: stop drinking water two hours before. Fun run at school: cheer from the side, again. Grey joggers: back of the drawer, just in case. Every mirror you pass: a quick check, without breaking stride, so nobody notices you checking.
None of it looks like anything from the outside. That is the point. You have become very good at it.
But every one of those tricks is a small no. No to the bouncing. No to the second glass of water. No to the joggers you actually wanted to wear. And the woman doing all that quiet maths is not quite the mum you set out to be. Not because of the leak itself. Because of everything you give up to keep it invisible.
The real weight of it:
It isn't the leak that wears you down. It's the maths. And the fact that the other mums aren't talking about it either, so everyone assumes she is the only one, and the silence keeps itself going.
5. And meanwhile the bill keeps running
And while you are doing all that maths, there is one sum you have probably never done: what the just-in-case habit actually costs.
A liner, pad or towel costs somewhere between 30p and £1.20 each. Even on cheap liners, two a day, you're quickly looking at £40 to £70 a year. Move up to pads on active days and that figure climbs straight away.
Why the bill grows instead of staying flat:
Leaks you only catch don't change on their own. Add it up over ten years and you're past a thousand pounds. Before any price rises.
| What disposables cost you | |
|---|---|
| After 1 year | about £55 |
| After 3 years | about £165 |
| After 5 years | about £275 |
| After 10 years | about £550 and up |
| What you're left with | nothing |
The worst part:
This is a subscription you never cancel and that gets more expensive every year. There's no point at which you're finished paying.
Five reasons, one conclusion
It isn't the brand
The problem isn't that you're buying the wrong brand of liners. And it isn't that you need to move up to a thicker pad.
The problem is that every disposable starts from the same idea: that something has to go in your underwear.
You do not need a better liner. You need underwear that makes the whole question disappear.
That idea is the problem.
The solution
Not a layer in your underwear. The underwear itself.
Livia Flow is just underwear. You put it on in the morning like any other pair. The protection is simply already in it.
Why four layers work better than one sponge:
Layer 1, the wicking layer. Pulls moisture straight off your skin and passes it downwards. This layer holds nothing itself, it only moves it along. That's the whole difference from a liner or pad, which keeps moisture at the surface.
Layer 2, the absorbent core. This is where the moisture is stored, in the middle of the fabric. Far from your skin, where it can't cause heat build-up or friction.
Layer 3, the leakproof layer. Keeps moisture in, but sits beneath the core rather than against your skin.
Layer 4, the outer fabric. Soft bamboo. Bamboo is naturally breathable, so heat can escape instead of staying trapped.
What it isn't: not a medical device, not an adult nappy, not a pharmacy box you pay for with a red face. Just underwear, that happens to be leakproof.
Same problem, two mechanisms
All five points above come from a single design choice. Put them side by side and you can see exactly where it goes wrong.
| Liner, pad or towel | Livia Flow | |
|---|---|---|
| What it does with moisture | soaks it up and holds it at the surface | pulls it away and locks it in the core |
| Where the moisture sits | against your skin | far from your skin |
| Heat | plastic traps it | bamboo lets it through |
| Friction | shifts and folds over | stays put like underwear |
| Fragrance and bleach | often present | not needed |
| Per day | 3 to 4 changes | put on once |
| After 10 years | 7,000 thrown away | the same drawer of underwear |
The heart of the difference:
In a liner or pad, one layer of material has to do everything at once: soak up and hold. Here each layer does one job. The top one only has to let moisture through, and that happens many times faster than soaking it up.
The proof
A full glass of water, all at once
We started with what a liner can handle: a few drops. This is the other side of that story.
Not a few drops. A full glass. All at once, exactly the way a leak arrives: suddenly and under pressure. That sudden, all-at-once arrival is exactly how a sneeze-leak works. This is the test a liner fails and this underwear passes.
What you're watching happen:
The water disappears through the wicking layer and is held in the core. Nothing runs off the sides. Nothing sits on the surface. And the outside stays dry.
Do this test at home over the sink yourself, before you wear a pair for a day. Most women do, and it's the exact moment they start believing it.
And the washing?
Rinse in cold water if you like, then straight in the machine at 40 degrees with everything else. No soaking, no separate cycle, no special detergent. It is laundry, not a project. You have enough projects.
Who this is for
For anyone who recognises this, at any age:
- A leak when you sneeze, cough, laugh or lift, since having children
- While your body is still recovering after giving birth
- Running, jumping or working out
- The last days of your period
- Through the menopause, when everything is shifting
- Or simply because you've had enough of the daily just-in-case

Thousands of women got here before you. Most of them thought they were the only one too.
From one of us
Mine started after my second baby
Livia Flow was started by my mum and me. Different ages, same problem: hers arrived with the menopause, mine after my second baby. We did not tell each other for far too long, which tells you everything about how this works.
We designed the underwear we could not find. One question decided everything: would you wear these even if they did not protect you? The answer had to be yes.
Julia, co-founder
This isn't about staying dry.
It's about ending the maths.
About saying yes to the trampoline before you've worked out an excuse. About the second glass of water before your gym class. About the grey joggers, worn because they were on top of the pile.
