How many diapers a baby goes through in a day can depend on their weight, age, and diaper size, but it may range from 5 to 12 diapers per day.

Here is the poop: Babies go through a lot of wet and soiled diapers during those first few weeks.

To prepare for this phenomenon, most parents build a stockpile of diapers before the baby arrives. This can be an overwhelming task for both seasoned and first-time parents. When stocking up, you need to consider many factors, such as the baby’s weight, diaper fit, and your finances.

You may have many questions: Should you add diapers to your registry, or purchase them yourself? How quickly do babies outgrow the smallest diaper size? How many newborn diapers do you actually need? Should you stock up on larger diapers as well?

Read on for the answers to these questions and many more.

How many diapers do you need?

Hopefully, you’ve already made the decisive disposable or cloth diaper choice. If you haven’t, that’ll be one of your first decisions to make.

Parents who choose to use disposable diapers quickly understand how a baby can go through about 3,000 disposables in their first year alone. Experienced parents may already be loyal to one brand, but for first-time parents, the many options may feel overwhelming.

People often give newborn diapers as gifts at baby showers, though most newborns gain about 3 pounds during the first month, and babies born with a higher birth weight tend to skip this diaper size completely.

You can always register for different sizes, but remember, you’ll need room to store them. If your space is limited, you don’t need to stock up on more than two sizes at once; you can ask for gift cards instead.

The following chart can help you stock up on disposable diapers. Keep in mind that all babies are different, and these numbers are just an estimate to help you prepare.

Note:

Babies come in all shapes and sizes and grow at their own rates. As such, it’s hard to determine how many diapers a particular baby will use. We researched various suggestions from experienced parents, average baby weights, and other factors to determine a suggested number for stockpiling. We encourage saving all receipts so you can return or exchange any diapers you don’t use.

Diaper size	Weight	Age range	Daily use	How many
preemie	under 6 lb	premature	as needed	as needed
newborn	up to 10 lb	first few weeks only	8 to 12 per day	2 to 3 packs or1 to 2 boxes (based on 140 per box)
size 1	8 to 14 lb	birth to 4 months	8 to 10 per day	13 packs (about 40/pack) or 3 to 4 boxes (based on 164 per box)
size 2	12 to 18 lb	3 to 8 months	8 to 9 per day	about 15 packs (about 37/pack) or 4 boxes (based on 142 per box)
size 3	16 to 28 lb	5 to 24 months	6 to 7 per day	27 packs (about 36/pack) or 7 boxes (based on 136 per box)
size 4	22 to 37 lb	18 to 36 months	5 to 7 per day	17 packs (about 23/pack)
size 5	over 27 lb	older than 3 years	as needed	as needed
size 6	over 35 lb	older than 4 years	as needed	as needed

Starting out

You can always start small. Try stockpiling no larger than size 1, just in case you don’t like the first brand you try.

Once you get a feel for fit, cost, brand, and size, go ahead and purchase more — up to an entire year’s worth or more of diapers. When planning, keep in mind your baby’s weight and rate of gain. Try to avoid paying full price for diapers unless it’s an emergency (more on saving on diapers below).

Different brands may work better or worse for different babies, so be open to trying a few different diapers before you decide on the right ones for your baby. Sometimes, a diaper that costs a little more is a better fit and works better, making it worth the extra money.

Frequency of changes

You’ll need to change your baby’s diaper every time they urinate or have a bowel movement, or at least every 2 to 3 hours during the first few weeks.

According to a 2023 survey by the advocacy group the National Diaper Bank Network, many parents report having difficulties affording diapers: 46% said they reduced other expenditures to afford diapers, and 35% said they cut back on food to afford diapers.

Many parents may consider changing diapers less frequently to make their supply last longer. However, making those last few diapers last just a little longer can ultimately lead to diaper rashes and yeast infections.

Sizing up

If your baby’s weight overlaps two different diaper sizes, it’s generally best to go with the larger size diaper.

You’ll know it’s time for a larger size when you see your baby’s skin has become irritated, red, or marked due to the elastic leg openings digging into their legs or waist, it becomes difficult to close the diaper over their stomach, or both.

Ideally, two fingers should fit between the diaper waistband and your baby’s stomach and one finger between your baby’s leg and the diaper’s leg elastic. The top of the diaper’s waistband should be at least 2 inches below your baby’s belly button. Diapers that sit too low on a baby’s back will be more prone to blowouts.

Another indicator that a larger size is needed is leaking diapers. If the diaper can’t contain the moisture between changes, your little one might be ready for the next size up.

Cloth diapers

Parents who chose the cloth diapering method should have at least 20 newborn diapers on hand. It may sound excessive and expensive (albeit a one-and-done expense), but we promise it’s a reasonable number to stockpile.

One of the bonus features of cloth diapers is that many styles that fit newborns are also adjustable to fit your baby as they grow — even up through the potty training years.

Wash no more than 12 to 18 cloth diapers at a time. Some families have as many as 24 or as few as 14 cloth diapers in each size, depending on the amount of laundering they are prepared and willing to do.

There are also parents who ultimately use cloth diapers yet choose to use disposable diapers for the first month due to the heightened number of diaper changes during that time or for on-the-go or babysitter backup.

How much do diapers cost?

It’s mind-boggling to see the numbers, realizing you’ll probably buy more than 100 ginormous disposable diaper packs.

At an average of $0.25 to $0.30 per diaper, a 1-week supply of diapers can cost around $25 to $30, and 3,000 first-year diapers at an average of $0.30 per diaper (or $0.25 cents per diaper if you buy in bulk) add up fast.

Based on diaper costs and daily changes, the average family spends around $1,000 in the first year on disposable diapers and supplies. Alternatively, the cost for a stock of cloth diapers could be more expensive upfront but may be less in the long run.

You’ll also need to purchase diaper wipes, creams, and all the other diapering accoutrement you deem essential, regardless of which type of diapers you use.

Wipes

Exactly how many wipes will you need per diaper change? That depends. A single change may take as few as 1 or as many as 10 wipes.

If you average five wipes per change (generously speaking) and consider 3,000 diapers changed in the first year, you’re looking at about 15,000 total wipes.

If there are 100 wipes in a package, you’ll purchase about 150 packs of wipes before your baby is potty trained. If one package is about $3, that’s $450 total, so buying in bulk may be a great way to cut costs.

If you have the space to stockpile wipes, go for it. Otherwise, always have at least two to three extra packs of wipes on hand. You will always find uses for wipes, even long after your diapering days. Nowadays, you may even want to consider a bigger stockpile of wipes in case of natural disasters and emergencies.

Alternatively, you can opt for reusable wipes, which can be used with water or a cleansing spray designed for diaper changing and may cut down on costs.

Ways to save

There are ways to save money on diapers. Sometimes, you can even combine a few of the suggestions below.

Keep in mind that buying larger package sizes generally means lower costs per diaper, but buying smaller packs may allow you to use more coupons. If your little one is solidly within a size range, purchasing the largest package you can splurge on can be a wise investment.

Coupons: In addition to newspaper and postal advertisements, pay attention to online website ads, emails from parenting websites, social media ads, and websites like Coupons.com and Freebies2Deals.com.
Cash back apps: These rebates are often used in addition to coupons.
Sales: Buy extra in advance when there is a good sale on diapers at the local convenience or grocery store. The best deals on diapers and wipes are often found at drugstores like CVS, Rite Aid, and Walgreens, with programs giving additional discounts when certain items are purchased.
Subscribe and save: Retailers like Amazon and Walmart have subscribe-and-save options, deliver diapers on a regular schedule, and offer free trials.
Clubs and rewards programs: Check out retailers like Sam’s Club or Costco for shopping in bulk or receiving cash back on other in-store products, and look at the individual programs offered by each brand, like Pampers Rewards and Honest Bundles.
Diaper banks: The National Diaper Bank Network, a nonprofit organization, has diaper banks across the United States and provides diapers to families who can’t afford them. To find a diaper bank near you, visit the website. If there isn’t a diaper bank near you, local religious and social service organizations often help families in need.

Takeaway

All babies are different. When deciding which type of diaper and how many to purchase, ask other parents in your life which brands they prefer and why.

Whether you use disposable or cloth diapers, no matter diaper size or brand, having a smart stockpile on hand can save you money and stress and help you feel more at ease and prepared for your baby’s arrival.
