Short answer: it depends on how old your child is, how many changes you do per day, and how you buy your diapers. A newborn goes through far more diapers than a two-year-old, and buying single packs in store gives a completely different monthly price than a subscription. Here we work through the whole equation, no guesswork.
How many diapers you'll use per month
The number of diapers is the biggest factor behind the monthly cost. Newborns need changing often, sometimes at every feed. The older your child gets, the fewer changes per day.
Our monthly boxes are sized for exactly that, and give a good picture of real-life use:
- The Mini (3 to 5 kg): 200 diapers per month
- The Newborn (4 to 7 kg): 216 diapers per month
- The Baby (6 to 9 kg): 192 diapers per month
- The Toddler (8 to 14 kg): 150 diapers per month
- The Kiddo (10 to 16 kg): 140 diapers per month
- The Explorer (14 to 20 kg): 130 diapers per month
The pattern is clear. Usage drops as your child grows, from over 200 diapers per month at the start to just over 130 in the largest sizes. So your diaper budget won't look the same for the whole diaper years.
What affects the price per month?
1. The price per diaper
Diapers come in every price range, from budget brands to premium diapers. But don't just compare the pack price. Always work it out as price per diaper. A big box with a lower unit price often works out cheaper per month than small packs that feel cheap at the checkout.
2. How you buy
Buying single packs in store means impulse prices, spur-of-the-moment purchases when you've run out, and the occasional pricey panic buy at the nearest gas station. A subscription gives you a predictable monthly price, and with Bammies free shipping is included with every delivery. You can pause, change size or cancel whenever you like, with no commitment at all.
3. Leaks and the wrong size
A leaking diaper costs more than it looks. Extra changes, extra laundry, extra diapers. The wrong size is the most common cause of leaks, so the right fit is actually a budget question. Not sure about the size? Our size guide and our sample kits help you find the right fit before you buy a whole box.
4. The hidden costs
The diaper budget is more than the diapers. Ointments and creams for diaper rash can become a recurring expense if your baby's skin isn't happy in the diaper. Many parents who've switched to bamboo diapers tell us they've stopped using creams altogether. As one parent wrote: "Not once have I used any creams, her skin is so happy in these diapers." Our innermost layer is made of 100% bamboo fibers, soft, breathable and with no lotions or fragrances.
Subscription or single packs, which is cheapest?
If you only count the shelf price, single packs can look cheap. But count the whole month:
- Shipping or trips to the store. With a subscription, shipping is included, every time.
- The right amount. A monthly box is sized for your child's actual usage, so you buy neither too much nor too little.
- Time. Diapers that turn up at your door are one less thing to keep in your head. That's hard to put a price on, but ask any tired parent.

How to keep diaper costs down
- Always count the price per diaper, not per pack.
- Change size at the right time. Leaks at the back or between the legs are often a sign it's time to go up a size.
- Test before you stock up. A sample kit with a few diapers costs little and saves a lot if the size doesn't fit.
- Adjust your subscription to your needs. With us, you change size, frequency or pause directly in your account.
- Factor in the skin. A diaper that's kind to skin can mean fewer creams and fewer worries. And if the diaper causes a rash, you get your money back from us.
Put your diaper budget on autopilot
So your monthly diaper cost comes down to quantity, price per diaper and how you buy. With a subscription, you get the right amount, in the right size, delivered to your door with free shipping. No lock-in, no surprises.
