How Many Cloth Nappies Do I Need? Your Complete Australian Guide
Quick Answer: How Many Cloth Nappies Do You Need?
If you’re preparing to start your cloth nappy journey, one of the first questions you’ll ask is: “How many cloth nappies do I need?” Don’t worry – we’ve been there, and we’ve got you covered! The answer depends on your washing routine, your baby’s age, and whether you’re using cloth nappies full-time or part-time. This comprehensive guide will help you calculate exactly how many reusable nappies you need for your family.
For full-time cloth nappy use:
- Newborns (0-3 months): 24-36 cloth nappies
- Babies (3-12 months): 20-25 cloth nappies
- Toddlers (12+ months): 16-20 cloth nappies
For part-time use: Start with 10-12 cloth nappies and supplement with disposables as needed.
These numbers assume you’re washing every 2-3 days, which is the recommended frequency for cloth nappies in Australia. Read on for a more detailed breakdown to suit your specific circumstances! Or jump straight in and try out our stash calculator.

Understanding Your Cloth Nappy Needs
How Many Nappies Does a Baby Use Per Day?
The number of nappy changes your baby needs varies significantly by age, and this is one of the key factors in working out your ideal stash size:
Newborns (0-3 months): 10-12 nappy changes per day
Newborns need changing more frequently – generally every couple of hours, including overnight when they wake for feeds. Those tiny tummies mean frequent bowel movements and lots of wet nappies!
Young babies (3-6 months): 8-10 nappy changes per day
As feeding patterns become more established, nappy changes decrease slightly. You’ll still be changing fairly regularly throughout the day and potentially overnight as well.
Older babies (6-12 months): 6-8 nappy changes per day
Once solid foods are introduced, nappy frequency reduces. Most parents find themselves changing nappies closer to 3-4 hours during the day.
Toddlers (12+ months): 5-7 nappy changes per day
Toddlers can go longer stretches between changes, and with a good night nappy, they may not need changing overnight at all.
How Many Cloth Nappies for Different Washing Routines
Your washing frequency directly impacts how many reusable nappies you need in your stash. It’s important to be realistic about how often you can commit to washing – there’s no point buying fewer nappies thinking you’ll wash daily if that’s not sustainable for your household!
Washing Every 2 Days (Most Common)
This is the sweet spot for most Australian families and prevents odour buildup. It also aligns well with most washing routines when washing a full load of nappies.
Simple calculation: (Nappies used per day × 2 days) + 4-6 extras for washing/drying time
Examples:
- Newborn using 12 nappies/day: (12 × 2) + 6 = 30 nappies (or 24-36 range)
- Baby using 8 nappies/day: (8 × 2) + 6 = 22 nappies
- Toddler using 6 nappies/day: (6 × 2) + 4 = 16 nappies
Washing Every 3 Days
Some families prefer washing every three days, especially if they have larger stashes or slower drying times.
Calculation: (Nappies used per day × 3 days) + 6-8 extras
Examples:
- Baby using 8 nappies/day: (8 × 3) + 8 = 32 nappies
- Toddler using 6 nappies/day: (6 × 3) + 6 = 24 nappies
Note: For newborns, this would require 42+ nappies which is unrealistic for most families. Stick to 2-day washing during the newborn stage.
Washing Daily
Daily washing works if you’re committed to the routine and have fast-drying nappies. I have a mix of microfibre pocket nappies and thicker bamboo all-in-ones. On a sunny Queensland day, the microfibre inserts will easily dry within a couple of hours, whereas the bamboo might take around 6-8 hours to fully dry.
Calculation: (Nappies used per day × 1 day) + 6-8 extras for rotation
Examples:
- Baby using 8 nappies/day: (8 × 1) + 8 = 16 nappies minimum
- Toddler using 6 nappies/day: (6 × 1) + 6 = 12 nappies minimum
Important to note: While daily washing can work, it increases your water and energy costs and requires strict routine adherence. If you get sick, have a busy day, or the weather turns, you’ll have no backup nappies. For stress-free cloth use, 20+ nappies is much more comfortable.
How Many Cloth Nappies Do I Need to Start?
Many Australian parents wonder if they need to buy their entire stash upfront. The great news is you absolutely don’t have to! Here’s how you might approach building your stash:
Beginner Starter Pack: 6-8 cloth nappies
Perfect if you’re:
- New to cloth and want to test the waters
- Trying different types of cloth nappies (all-in-ones, pockets, fitted)
- Testing various brands to find your favourites
- Using part-time alongside disposables
- Using cloth on weekends or daycare-free days
This is how I got started – I bought one pack of disposables and gave myself a week to get used to having a newborn before I tackled the cloth nappies. Within a week though, I found myself keen to jump in after all my research!
Part-Time Stash: 10-15 cloth nappies
Great for families who:
- Use cloth at home, disposables when out
- Want a manageable washing routine
- Prefer a lower upfront cost
- Still want significant environmental and cost savings
Remember, it certainly doesn’t have to be an all-or-nothing situation! Every single reusable nappy you use will reduce the number of disposables going to landfill.
Full-Time Stash: 20-25+ cloth nappies
Ideal for:
- Complete cloth nappy coverage
- Comfortable washing buffer
- Maximum savings and sustainability
- Less stress if laundry gets delayed
- Having backups for heavily soiled nappies
This is the sweet spot where most full-time cloth families land. It provides enough nappies to cycle through comfortably while washing and drying one load.
Cloth Nappy Types and How Many You Need
Different nappy styles may affect how many you need in your stash, particularly because of drying times.
All-in-One (AIO) Cloth Nappies
How many: 20-24 for full-time use
All-in-ones are the easiest to use but take longest to dry because the absorbent part is sewn into the cover. Because everything is together, you’ll need slightly more to account for drying time, especially in humid Australian climates or during winter.
In colder climates or during the wet season when air-drying inside (I don’t own a dryer), the thick bamboo inserts in my AIOs can take a couple of days to completely dry. Therefore you may find you need more nappies, and some people consider around 36 nappies to be a good stash for these circumstances.
Best for: Beginners, partners, childcare, grandparents
Pocket Cloth Nappies
How many: 18-24 shells + 36-48 inserts
Pockets dry faster than AIOs since you separate the insert before washing. Many parents buy extra inserts (1.5-2x the number of shells) to boost absorbency for heavy wetters or overnight.
Best for: Customizable absorbency, quick drying, heavy wetters
Fitted Nappies with Covers
How many: 18-24 fitted nappies + 6-8 covers
Covers can be reused multiple times if not soiled (particularly PUL covers which can be wiped clean), so you need fewer covers than fitted nappies. This system offers excellent absorbency for night-time and heavy wetters.
Best for: Overnight use, newborns, maximum absorbency
Flat and Pre-Fold Nappies
How many: 24-36 flats/prefolds + 6-8 covers
The most economical option. Flats and prefolds dry extremely fast and last through multiple children, making them brilliant for both the newborn stage and later for boosting other nappies.
Best for: Budget-conscious families, fast drying, long-term durability
How Many Newborn Cloth Nappies Do I Need?
Newborns are the most demanding stage for nappy changes, going through 10-12 nappies per day. Here’s what Australian parents typically need:
Option 1: Dedicated Newborn Stash
20-24 newborn-sized nappies
Pros:
- Better fit for tiny babies (usually 3-5kg)
- Reduces leaking issues
- Can resell or save for next baby
Cons:
- Only used for 2-3 months typically
- Additional expense on top of your main stash
If your budget allows and you’re using cloth from the onset, dedicated newborn nappies can be fantastic. However, given newborns will grow out of them quickly, you don’t need them.
Option 2: One-Size-Fits-Most (OSFM) from Birth
24-28 OSFM nappies
Pros:
- More economical long-term
- One stash lasts birth to potty training
- No need to transition between sizes
Cons:
- May require extra boosting when small
- Can be bulkier on newborns
- May not fit some brands until 4-5kg
You don’t necessarily need specific nappies for a newborn as they are in them for such a short time. However, the OSFM can be a little trickier to get a good fit, even with the newborn fit hacks that many brands offer.
Option 3: Budget Combination
12-15 newborn nappies + 12-15 OSFM nappies
This gives you the best of both worlds – good fit in the early weeks, then transitioning to your long-term stash.
Option 4: Flats or Prefolds for Newborns
24-36 flats/prefolds + 6-8 newborn covers
The most economical newborn option! They’re quick to dry and can later be used to boost your other nappies as your baby grows. This is a very popular choice for many cloth families.
How Many Reusable Nappies Do I Need for Twins?
Cloth nappying twins is absolutely possible! Many Australian twin parents successfully use reusable nappies, and the savings are even more substantial.
Twins stash: 40-48 cloth nappies minimum
- Essentially double the single-baby requirements
- Consider washing daily or every 1.5 days to reduce stash size
- Each twin uses 10-12 nappies per day as newborns
- Having 45+ nappies allows for every-second-day washing
Money-saving tips for twins:
- Buy in bulk bundles for discounts
- Consider faster-drying styles (pockets, prefolds)
- Invest in a larger washing machine if possible
- Join cloth nappy hire services to try before committing
- Look for council rebates to offset costs
How Many Night Nappies Do I Need?
Many families use boosted cloth nappies or specific night nappies for overnight use.
Dedicated night nappy stash: 3-5 night nappies
- More absorbent than day nappies
- Often fitted nappies made from bamboo or hemp
- Can be used with your regular covers
- Rotate through while others wash and dry
Boosters for night: 6-10 additional booster inserts
- Add to your regular nappies for overnight
- Hemp and bamboo offer excellent absorbency
- More economical than buying separate night nappies
- Flats are brilliant for boosting once bub outgrows the newborn stage
Calculating Your Perfect Stash Size
Use this simple formula to calculate exactly how many cloth nappies you need:
(Daily nappy changes × Days between washes) + Buffer nappies = Total stash size
Or use our simple calculator at the top of this article.
Buffer nappies account for:
- Nappies currently in the wash
- Nappies still drying
- Emergency extras
- Heavily soiled nappies needing extra washing
- Days when laundry gets delayed (illness, busy schedules, weather)
Your calculation:
- Count how many nappies your baby uses in 24 hours
- Multiply by days between washes (be realistic!)
- Add 4-6 buffer for newborns/babies, or 6-8 for toddlers
- Round up to ensure comfort
Example for a 4-month-old:
- Uses 10 nappies per day
- Washing every 2 days
- (10 × 2) + 6 buffer = 26 cloth nappies
However, there is no harm in building up your stash slowly and keeping some disposables on hand as a backup until you work out your routine. Just a warning though – the cute styles and prints can be a little addictive, so many people find themselves with a sizeable stash over the years!
Cost Comparison: How Many Cloth Nappies vs. Disposables
Understanding the financial investment helps you decide on stash size. If you’re wondering whether cloth nappies are cheaper than disposables, let’s break it down:
Disposable nappy costs (Australian average):
- 6,000-8,000 nappies from birth to potty training
- $0.30-$0.50 per disposable nappy
- Total cost: $2,000-$4,000 per child
Cloth nappy investment:
- 24 quality cloth nappies: $600-$900
- Additional inserts and accessories: $100-$200
- Washing costs over 2.5 years: $400-$600
- Total cost: $1,100-$1,700 per child
Savings: $900-$2,300 per child with cloth nappies
For multiple children: Use the same stash for 2-3 children, saving $4,000-$8,000 total. Plus, there is a huge sense of satisfaction knowing you’re minimising your environmental impact and saving money at the same time!
Don’t forget to check if your local council offers a rebate on reusable nappy purchases – this can offset your initial costs significantly!
Building Your Stash Gradually
You don’t need to buy all your cloth nappies at once. It can be wise to get started slowly with just a few nappies and work your way up to a full stash to give yourself time to work out your routine and your preferred style of nappies.
Months 1-2: Start with 6-8 nappies
- Test different brands and styles
- Use part-time while learning
- Identify your preferences
- Attend local cloth nappy markets or check Facebook buy/sell groups
Months 3-4: Expand to 15-18 nappies
- Focus on styles that work for your family
- Use cloth most days
- Supplement with disposables when needed
- Consider a nappy hire service to trial more brands
Months 5-6: Complete stash with 20-24+ nappies
- Commit to full-time cloth
- Add night nappies and boosters
- Establish your washing routine
- Enjoy the satisfaction of your cloth journey!
Budget-friendly building tips:
- Watch for sales (Black Friday, End of Financial Year, Boxing Day)
- Buy second-hand from cloth nappy communities
- Join bundle deals from Australian brands
- Check if retailers offer trial packs to try different styles
- Look into cloth nappy lending libraries
