Don't worry, your baby can't read this

Being a mum is
f#@%n hard

A nappy that actually doesn't leak makes it a little easier.

The 3am problem

A leak doesn't cost you a nappy. It costs you the night.

It's never just the nappy.

  • Change the nappy. Then the singlet, the sheet, the mattress protector, and sometimes the mattress.
  • Settle a baby who is now wide awake. Cold, wet, and unhappy about all of it.
  • Do it again the next night. Because nothing about the nappy changed.

How it holds

Three things decide whether a nappy leaks. We built for all three.

  1. 01

    It seals at the legs

    Most leaks escape at the leg long before the nappy is full. Two cuffs at each leg, so when one is broken by a roll the other is still holding.

  2. 02

    It takes the volume

    About 500ml at size 4, locked away in the core as gel. The industry average holds about 350ml.

  3. 03

    It holds at the back

    Most blowouts escape up the back. A pocket across the back of the waist catches it before it reaches the waistband.

What's in it

Six materials. All of them named.

Here is each one and what it is doing in there.

  • Cotton Cotton Against the skin. No fragrance, no dye.
  • Polypropylene Polypropylene The dry layer. Keeps her skin dry, fewer rashes.
  • Fluff pulp Fluff pulp Soaks it up fast and spreads it right out.
  • Super absorbent polymer Super absorbent polymer Turns wee to gel so it cannot leak back.
  • Spandex Spandex The stretch at the waist and legs. No marks.
  • Polyethylene Polyethylene The outside layer, off her skin. Dry sheets.

Where the joking stops

We're serious about making amazing nappies. We just refuse to be boring about it.

  1. 1 Double cuff at the leg Two seals at each leg. If a roll breaks the first, the second is still holding.
  2. 2 A pocketed back A raised wall inside the back that catches it before it reaches the waistband.
  3. 3 100% cotton against the skin Cotton on the face that touches her, over a soft non-woven. It stays dry against her skin even when the core underneath is full.
  4. 4 More polymer inside More of the wee turns to gel, and gel cannot be squeezed back out.
  5. 5 A stripe that shows it is wet Changes colour, so you can see it without undoing anything.

FAQs

Questions.

What happens if it leaks anyway?
Tell us and we refund the box, within 30 days of delivery. Every baby is a different shape, and we cannot guarantee the fit always, so we carry that risk.
How is this different from the overnight nappy at the supermarket?

Five things.

  • A pocket at the back. It catches it before it reaches the waistband.
  • A double seal at the leg. If a roll breaks the first, the second is still holding.
  • 100% cotton against the skin.
  • Higher absorbency. About 500ml at size 4, locked away as gel.
  • Colours and a material you fall in love with.
I don't want to lock into a subscription before the baby arrives.
Then do not. Buy a single box and see how it goes. If you do subscribe, you can skip, resize or cancel by email, with no minimum term.
What size do I order?
Order by current weight. Newborn under 5kg, 1 is 4 to 7kg, 2 is 6 to 10kg, 3 is 9 to 14kg, 4 is 13 to 18kg, 5 is 16 to 23kg, 6 is 22kg and up. We send a free trial pack of the next size up before you need it.
What is actually in it?
Six materials: cotton, polypropylene, fluff pulp, super absorbent polymer, spandex and polyethylene. Fragrance free, no dye against the skin, chlorine free bleaching, PFAS free. All six are named on this page.
How much is it, and how long does a box last?
A$121 a box, or A$108.90 on the subscription. One price at every size. The count in the box changes as they grow, from 210 at newborn to 120 at size 6, so a box lasts the full month the whole way through. On the subscription that is about A$3.63 a day. We do not price it per nappy, because the number a night takes changes as they grow.
