After extensively testing nearly two dozen brands of top-rated diapers, we found several clear winners. The Huggies Little Snugglers and Huggies Little Movers were simply the best diapers overall, as they consistently proved the most reliable at preventing leaks while fitting kids of all sizes the best. Our co-authors put 21 of the best-rated and most popular diaper brands through a series of at-home lab tests to measure how well each diaper held liquid. After eliminating the poor performers, a panel of parents evaluated the diapers during real-world use with their babies and toddlers. The nine kids on our panel range from just 2 weeks old to 4 years old, so we could get a full picture of how these diapers suit kids of different ages and genders.
The following is a list of all the winners from the testing process:
- Best Diaper Overall: Huggies Little Snugglers, Huggies Little Movers
- Best Value Diaper: Kirkland Signature Diapers
- Best Eco-Friendly Diaper: Bambo Nature Dream Diapers
- Best Diaper For Sensitive Skin: HealthyBaby Diapers
- Best Diaper For Newborns: Coterie The Diaper
- Most Giftable Diaper: The Honest Company Clean Conscious Diapers
Parents spend a lot of time, money and energy on diapering, so we wanted to dig into finding the best diapers to lessen that load for parents. We’ve also done extensive testing on the best overnight diapers, so if you’re looking for a solution to nighttime leaks, you may want to consider that list as well.

*Main active materials
Huggies Little Snugglers (for younger babies) and Huggies Little Movers (for older babies and toddlers) are popular diapers for a good reason. We found them to be consistently good for all the kids in the testing lineup, ranging from newborns to preschoolers. They contained poop blowouts with almost 100% consistency (just a few snuck into the mix), didn’t leak, lasted well overnight on both babies and more active toddlers, had a flexible waistband that allowed for a snug fit and met expectations in terms of cost.
Absorbent And Comfortable With Few Drawbacks
During our at-home absorbency test, the Huggies diapers performed well. We were able to put 2 cups of water into the Huggies diapers before they started to leak. They also tended to soak up liquid slowly, which indicated they hold up longer before leaking. (Some diapers were immediately satiated during absorbency tests, and those diapers leaked earlier on in the process.) Huggies relies on fairly standard diaper materials for absorbency—namely, wood pulp and plastics—but the brand says the diapers are hypoallergenic (meaning they are fragrance-free, paraben-free, lotion-free and have no elemental chlorine bleach).
You may notice that Huggies diapers feel damp, basically saturated with liquid, before they start to actively leak. This is a good sign for fit (no leaks means no gaps), but a few parents noticed that their kids were a bit moist overnight.
Excellent Fit For Fewer Leaks
In terms of fit, the Huggies are remarkably consistent for kids with different body shapes and sizes. This is likely because the straps around the waist are thinner but more flexible than those of the other diapers we tested (this is called “tensile strength”), so you can cinch the diaper tightly around your child’s waist. One mom noted that this diaper was one of the few that fit her daughter, who’s in the 90th percentile for height and weight, and another mom called it “perfectly snug.” Huggies seem to fit true to size.
There are few downsides to the Huggies diapers, except that they’re disposable and not made with the most sustainable materials on the market. But this is also true for most of the other diapers we tested. When it comes to flexibility, versatility and minimal leaking, Huggies diapers can’t be beat.

Best Value Diaper
A Solid Diaper At A Much Reduced Price
Kirkland Signature Diapers
Average price: $0.18 per diaper at Costco | Materials: Wood cellulose fiber (pulp), sodium polyacrylate, polyethylene, polypropylene* | Fit: True to size | Absorbency: Medium
Best for:
- Budget shoppers
- Families that want fragrance-free diapers
- Costco members
Skip if:
- You prefer a more environmentally friendly option
- You want peak absorbency
*Main active materials
Co-author Jenni Gritters says she used Kirkland Signature Diapers for years, and her round of testing reaffirmed what she already knew: “They’re neither the best nor the worst option out there. But for the price, they do a solid job of keeping your child dry.”
‘Completely Serviceable’ And Totally Affordable
All of our parent testers ranked the Kirkland diapers either first, second or third on their list of best diapers, noting that the kids didn’t experience leaks, although a few of them (including one of the older toddlers) were soggy after a night of sleep. Several moms praised the stretchy waistband, which has more give than the Huggies and allows for a secure fit.
Kirkland diapers fit on par with Huggies diapers, true to size without much sag. If you think these two diapers seem similar, you’re not wrong: Both are made by Kimberly-Clark, which also makes Kleenex, among other products. Each diaper has moderately wide tabs plus a wetness indicator, which can sometimes be faulty. This didn’t bother us, though, because as most parents know, you can usually tell, or smell, when they need a change.
Costco’s diapers are fragrance free, which is a bonus, and produced without elemental chlorine. The rest is fairly standard fare, including wood pulp, superabsorbent polymer (SAP) and also some dyes to print colors and designs on the diapers.
In the absorbency test, the Kirkland diapers were solidly middle-of-the-road. They absorbed liquid for about 5 minutes and then just stopped, seeming to have reached max capacity. This tells us that these diapers will need to be changed more often than some of the others, which is expected given the budget price. Kirkland diapers are quite reasonable, at about $0.20 each, although you’ll need to be a Costco member to take advantage of the extra low price. Amazon sells the same diapers for a slightly higher cost. As your kid gets bigger, the price of the diapers gets incrementally higher.
Ideal For Sensitive Skin
“My toddler son has sensitive skin, and he always gets diaper rashes when we switch him to a non-Kirkland brand of pull-ups,” says Gritters. “I’d attribute this to the fact that Kirkland diapers are hypoallergenic and lotion and fragrance free.” Other moms noticed the same: no diaper rashes to be found when testing. That said, a few online reviewers mentioned rashes.
One of our diaper testers summed up the Kirkland diapers best: “They’re completely serviceable; nothing special but also nothing bad about them as far as our experience goes.” If you want to know more, read our full Kirkland Signature Diaper review.
Best Eco-Friendly Diaper
A More Planet-Friendly Option
Bambo Nature Dream Diapers
Average price: $0.46 per diaper | Materials: Polypropylene, polyethylene, TCF (natural) pulp, absorbent polyacrylate (SAP), synthetic rubber* | Fit: Small | Absorbency: High
Best for:
- Sensitive skin
- Supporting a sustainable brand
- No dyes, fragrances, chlorine or phthalates
Skip if:
- They don’t fit your child well, which allows for leaks
*Main active materials
Absorbent For Some, But Not All
Our testers were entirely split on the effectiveness of Bambo Nature Dream Diapers. Several (notably, those with girls) loved the Bambo for its absorbency, light and thin structure and all-night dryness. But the others hated the Bambo diapers (notably, all the parents of boys), finding them to be leaky and too narrow.
What it comes down to is fit: This diaper is narrower than the others. If your child doesn’t have the right fit, poop and pee will seep out the sides. This is (obviously) terribly annoying and not worth the price of admission, especially because these are not the cheapest diapers we tried, at $0.46 a pop. But if you like Bambo Nature’s mission, it may be worth trying its diapers. When in doubt, size up.
Bambo’s diapers were the best performers in our absorbency tests, which was slightly shocking given that some testers reported leaks. But this just speaks to needing to find the right fit for your baby. These diapers held more than 2 cups of water without leaking, but we did observe that the fill was a bit unbalanced; they seemed to absorb more in the front portion, which could lead to leaking for some.
A Sustainable Mindset
Speaking of mission, disposable diapers are controversial; they fill our landfills and do not break down quickly. A number of brands are trying to fix this. Bambo Nature relies on a sustainable supplier for the materials used in its diapers including a wood pulp gathered from sustainable forestry methods where additional trees are planted to replace those harvested. The supplier also relies on wind power and more energy-efficient machinery. No chlorine, fragrances, dyes, phthalates, parabens, formaldehyde or other concerning chemicals are added to its diapers, making them gentle on sensitive skin. Its supplier claims to recycle 95% of its production waste.
They’re produced in Denmark, and the company is transparent about the manufacturing processes, too. Bambo Nature diapers do still contain SAP and some plastics, which form the basics of any disposable diaper, but they’re made without all those additional non-desirables and with a more environmentally friendly mindset. This has earned them the seal of approval from several allergy focused organizations, including the The Asthma & Allergy Nordic label. If you prioritize sustainable purchasing—and can afford the steeper price tag—the Bambo Nature Dream Diapers tested better (for most of us) than other diapers marketed as more natural picks.
Best Diaper For Sensitive Skin
A Lightweight, Absorbent Diaper That Discloses Its Full List Of Ingredients
HealthyBaby Diapers
Average price: $0.59 per diaper (size 3)|Materials: Polyethylene, polypropylene, sodium polyacrylate, wood pulp, calcium carbonate, printed ink made without lead or heavy metals (more info here)*|Fit: True to size|Absorbency: Medium
Best for:
- Those who prefer a diaper that’s gentle on skin and the environment
- Those who prefer to see the full list of diaper ingredients
- Warm weather and travel
Skip if:
- You want diapers with a wetness indicator
*Main active materials
One of the trickiest parts of finding a diaper for kids with sensitive skin is that companies don’t always disclose the ingredients that go into their products. Baby diapers are regulated by the Consumer Product Safety Commission (CPSC), according to Sydney Swanson, a scientist and analyst with the Environmental Working Group (EWG). The CPSC doesn’t require diaper manufacturers to publish a list of ingredients, although it does require that diapers are tested for lead.
That lack of information can leave caregivers of little ones with sensitive and eczema-prone skin wondering about which diapers may be safe for their kiddos. That’s why we were so excited to try HealthyBaby Diapers, which publishes a full and comprehensive list of ingredients that go into their products. They’re also the first diapers to be verified as free from a list of concerning chemicals by the EWG.
Thin, Soft And Super Absorbent
Not only are HealthyBaby Diapers free from parabens, phthalates, fragrances, optical brighteners, chlorine, latex and lotions, but their lightweight construction is also very absorbent. These diapers soaked up 1.5 cups during an at-home test in which we immersed the diapers in a bowl of water for 10 minutes—considerably more than several competitors we tested for sensitive skin, including Parasol, Terra and The Honest Company.
HealthyBaby Diapers were among my favorites for hot summer days and travel. Their thin, lightweight design makes it easy to stuff six or seven of them into a diaper bag. They’re also soft, with a feel that reminds me of Bambo Diapers (our eco-friendly pick).
One tester complained that these diapers felt a bit slippery when trying to get them on her wiggly little one. Another noted that they experienced a blowout and two leaks with these diapers during naps and in the car seat. Still, most of our testers were impressed by the diapers’ effectiveness. “I’m a big fan of these diapers and would buy them again,” wrote one mom on our testing panel. “I have in fact recommended them to other parents.”
Plain And Undyed, Without A Wetness Indicator
HealthyBaby Diapers start at size 1 (6 to 12 pounds) and go up to size 6 (27-plus pounds). They don’t feature any patterns or designs. A couple of testers noted that they missed the wetness indicator on these diapers, which the brand has eliminated as it seeks to find an alternative to quaternary ammonium compounds, which can irritate skin and has been linked to other health concerns, according to the EWG.
As with many premium diapers, HealthyBaby Diapers tend to be on the pricier side. You can save some money by ordering them directly from the brand and/or signing up for a subscription. You may also want to check out The Honest Company Clean Conscious Diapers, our pick for the most giftable diapers, which are also free from skin irritants like fragrance, chlorine, parabens and latex.
Best Diaper For Newborns
A Plush, Premium Option That’s Best Ordered Through A Subscription
Coterie The Diaper
Average price: $0.41 per diaper (newborn)| Materials: Sodium polyacrylate, chlorine-free wood pulp, polypropylene, polyester, polyethylene*| Fit: True to size| Absorbency: High
Best for:
- Those who prefer diapers that eliminate common skin irritants
- Those who prefer diapers that are more environmentally friendly
Skip if:
- You don’t want to sign up for a diaper subscription
*Main active materials
Folks are divided on Coterie: Celebrities have referred to them as the “Rolls-Royce of diapers,” while some parents wonder whether they’re really worth the fuss (and high price tag). Infants’ skin is thinner and more vulnerable than adults, which leads some caregivers to seek out diapers that eliminate common irritants.
Coterie’s The Diaper is free of many concerning chemicals and features a cloud-like construction that our testers repeatedly called “soft” and “cottony.” Coterie is also available in a full range of sizes, so if you fall in love with these diapers when your baby is tiny, you can use them all the way through the toddler years.
A Deluxe Diaper That’s Gentle On Newborn Skin
Coterie diapers are free of fragrance, lotion, latex, rubber, dyes, alcohol, heavy metals, parabens, phthalates, pesticides, chlorine bleach, VOCs or optical brighteners. “Although my newborn has not had skin reactions from diapers so far, I feel good knowing he’s wearing a cleanly made, soft diaper,” wrote the mom of a 2-and-a-half-week-old baby on our testing panel.
“In an at-home leak test, in which I added 2 tablespoons of water to each diaper, noting which ones leaked first, Coterie diapers were the top performer,” says co-author Jessica Bernhard. The Diaper soaked up a whopping 2.5 cups of water before water began trickling out the sides. “I also tested these diapers when evaluating the overnight diapers. Coterie consistently kept babies in our panel of testers dry for up to 12 hours of sleep.”
A couple of testers noted that The Diaper felt a little more bulky than other more eco-conscious diapers like Bambo and The Honest Company. That said, we found The Diaper to be true to size with a nice “bum shape,” as one tester put it.
Stretchy, Soft In A Range Of Sizes
Coterie diapers are pliable and move with babies well, although they feature less of an elastic waistband compared with Huggies and The Honest Company. “During testing, my older 16-month-old climbed up, down and all around while wearing The Diaper,” says Bernhard. “They stuck with him and didn’t allow any leaks.”
Coterie diapers start at the newborn size (less than 10 pounds) and go all the way up to size 7 (41-plus pounds). They’re also available in a training-pant style that our testers loved. “We did not have a single leak, which I’m pretty impressed with,” one tester of The Pant reported.
To cut down on cost, consider signing up for a subscription, which saves 10% (after interviewing many parents about dependability and ease of use, we also found that Coterie is one of the best diaper subscription services). But if the price doesn’t fit into your budget, you may want to consider The Honest Company, another one of our top picks, which costs approximately $0.38 per diaper (as opposed to Coterie, which starts at about $0.41) and is also a gentle option for newborn skin.

An Incredibly Cute Diaper With Attractive Designs That Works
Honest Company Clean Conscious Diapers
Average price: $0.38 per diaper | Materials: Wood cellulose fiber (pulp), sodium polyacrylate, polyethylene, polypropylene* | Fit: Small | Absorbency: Medium
Best for:
- Gifting at a baby shower
- Stylish diaper that appeals to kids and parents
Skip if:
- Your kid is in the higher height/weight percentiles (or just size up)
- You need something more affordable
*Main active materials
The Honest Company Clean Conscious Diapers clearly ran small, but they’re among the cutest diapers we tried, with fun, adorable prints. The 4-year-old tester adored the prints as much as her mom, especially the banana ones. Plus, the designs are certainly stylish without relying on character licensing like Mickey Mouse or the latest superhero.
Absorbent Without Leaks As Long As You Have The Right Size
If you have the right size, you’ll find these to be great diapers—if expensive, at $0.42 cents each—that rarely leak. Able to take in a little less than 2 cups of water, they performed well during overnights and did well in the absorbency test. The Honest Company diapers have wider, flatter absorbency panels than some of the other diapers tested, which is great for kids with wider body types.
However, if you don’t have the right fit, you’ll experience blowouts and pee leaks galore. That’s the biggest drawback of these diapers: the sizing. “I loved these for my daughter for the first few weeks; then, she quickly grew out of them,” says Gritters. The 10-month-old boy in the group experienced the same thing, and quickly needed a size 4 instead of a size 3 diaper.
Chlorine And Fragrance Free
The Honest Company diapers are fragrance-free and don’t have chlorine, which we appreciate. The brand’s wipes are plant-based, but the diapers are made with standard wood pulp and plastic ingredients. They do use plant-based materials on the back sheets of their diapers, though, so there’s less plastic than other brands.
Overall, we think these are a fun option for gifting at a baby shower, especially the pre-made cake-shaped tower. They’re worth a shot for your baby—if you have the right size diaper, of course.

The Other Diapers We Tested
I tested eight additional diapers and researched another half a dozen brands. The diapers below didn’t pass my tests, but feel free to take a look in case there’s something here that appeals to your family.
Pampers Swaddlers and Pampers Cruisers: The Pampers diapers weren’t great, but they weren’t terrible either. They absorbed a decent amount of liquid despite having only a single, wide-panel construction. That said, most Pampers diapers are scented, and the moms on our panel all complained of leaks, especially overnight. Pampers fit true to size for most of our testers’ kids, and they have wide, stretchy panels that allow for a secure fit. However, the toddler in our lineup moved so much that the Pampers diaper completely fell off in the night. We take this to mean that Pampers’ waist panels aren’t quite secure enough for wiggly older children. They may work better for younger, less mobile babies.
Parent’s Choice Dry & Gentle Diapers: These Walmart brand diapers failed the absorbency tests early on. The crotch panel was too narrow for one tester’s daughter; she experienced near-constant leaking even during a short nap. They may be budget-priced (just $0.18 per diaper), but they fit small and are hard to secure tightly, leaving red marks around one child’s hips and legs. “My daughter also had a massive blowout in this diaper, and the mess was worse than what we had in any other diaper we tested,” says Gritters.
Seventh Generation Baby Diapers: Seventh Generation’s materials are biodegradable, and the diapers rely on FSC-certified wood pulp in its absorbent fluff, and the diapers are free of chlorine and fragrances. This is great,but we found them so leaky that they were barely usable. These were our least favorite diapers of all, hard stop. During a nap, one child’s shirt and pants were damp after less than an hour, and these diapers leaked constantly during the day. This is likely because the Seventh Generation diapers have only one absorbent compartment (many others have three), and it fills up immediately. It also started to fray quickly during the immersion tests.
Eco By Naty Eco Diapers: At around $0.56 per diaper, these were among the more expensive diapers we tested. However, the Bambo Nature diapers were a comparatively better option for most of the kids in our lineup; they leaked less and offered more flexibility. The Eco by Naty diapers performed just fine during our absorbency tests, soaking up at least 1.5 cups of liquid in their three panels. The three-paneled setup means that these diapers are wider in the crotch, though, and they’re harder to put on a wiggling baby than most of the other diapers we tried and run a bit small. And while most of us didn’t experience copious leaks, all of our children were soggy. They don’t have a wetness indicator, but they are free of fragrance, perfume, chlorine, bleaching and lotions and are certified by Oeko-Tex Standard 100.
Rascal + Friends Premium Diapers: Advertised as a direct competitor to Coterie, but far cheaper (at an average of $0.17 per diaper), we were curious about how these diapers would perform. Unfortunately, our assessment wasn’t great. These failed early in our absorbency tests, taking in just a cup of liquid before leaking. They also appeared to repel water when we soaked them; we take this to mean that pee might run off the fabric versus soaking in, which would explain the copious leaks our tester experienced while wearing them. Oddly, Rascal + Friends diapers worked well for some nights—but not others. The fit is tough; they’re wide and have some of the biggest tabs of any diaper we tested. So if you don’t get the exact right fit, you’re in for a load of laundry.
Dyper Simply Kind Diapers: Another pricey option (clocking in at around $0.45 per diaper for monthly subscription boxes), I was super curious to see how these compostable diapers performed. Yes, you read that right: compostable! This could solve our sustainability problems, I thought. It’s a great idea; Dyper replaces typical diaper ingredients like polyurethane with plant-derived alternatives, like bamboo. Unfortunately, the performance was terrible. This was the second diaper to fail with less than a cup of liquid in it. If a baby sits on their Dyper (which is inevitable) after a big pee, they’ll be damp. These diapers fit true to size, and they don’t tend to leak because of this good fit. But given the materials, your child will experience that “squish” sensation; after every nap and overnight, my daughter was vaguely damp. She was also more prone to diaper rash in these diapers, which makes sense if the child is sitting in wet stool or pee.
Up & Up Diapers: These Target brand diapers were some of the cheapest we tried, at $0.14 each. However, they just weren’t sturdy enough to be worth the discount. In absorbency tests, the Up & Up diaper failed early, but unlike the other diapers in the lineup, which started to leak when they hit peak capacity, the Up & Up diaper actively fell apart, with the absorbent lining emerging from the diaper itself. Up & Up’s diapers run large, and they have one of the wider waistband configurations with huge tabs you can use to secure the diaper around your baby’s hips. “While my daughter didn’t experience any leaks, and the diaper was just fine overnight, she worked her way out of them (the tabs aren’t very sticky and feel flimsy),” says Gritters. “I was genuinely concerned by how quickly these diapers fell apart.”
Pampers Pure Protection: Bernhard’s family used Pampers Pure Protection Diapers for both of her kids (currently 16 months and 4 years old). Pampers Pure absorbed a lot of moisture—2.5 cups of water—during the at-home leak test, and they have a true-to-size fit that’s substantial without being bulky. On the con side, our testing panel was concerned about the fact that Pampers discloses fewer of its ingredients compared with some competitor models. Pampers Pure are also made with lotion, which the experts we interviewed told us can irritate some kids’ skin.
Parasol Clear and Dry Natural Disposable Diapers: We were initially excited to test Parasol Diapers because of their ridiculously soft construction that made us feel like we were enveloping our babies’ bottoms in a cloud. They feature sweet gender-neutral prints our testers loved (our pack featured dogs). Unfortunately, the adhesive tabs you use to secure the diapers were small and considerably less sticky than competitor models, and a couple of testers noted that the diapers released fluff pulp (the material in the diapers’ absorbent core) while babies were wearing them. Parasol diapers also have a rectangular fit that may not work for every kid.
Terra Diapers: We were excited to consider these diapers as a contender for the best diaper for sensitive skin, thanks to an eco-friendly construction that forgoes many of the ingredients that can bother kids’ skin. Terra Diapers were among the most absorbent diapers we put through the at-home lab tests. They soaked up 55 ounces of moisture during the immersion test and absorbed 2.25 cups of water before leaking. During panel testing, however, we found Terra Diapers to be less flexible and harder to secure than competitor models. “The fit is a bit odd,” as one tester put it, and two of our testers experienced leaks with these diapers.
Mama Bear Gentle Touch Diapers: We were initially drawn to this diaper brand because they may be easier to find online and in some pharmacies and are Oeko-Tex Certified, but they performed poorly during our at-home absorbency and leak tests.
Babyganics Triple Dry Diapers: These diapers are also widely available and are free from a number of major irritants like latex and fragrances. However, they were one of the least absorbent in our at-home tests and didn’t advance to panel testing.
Earth & Eden Baby Diapers: These diapers have fairly few skin irritants and can be found at major retailers online. But they didn’t perform as well as our top picks in the absorbency and leak testing, so they didn’t advance to the next round.
Pura Baby Diapers: We also considered Pura Baby Diapers as a contender for our newborn pick and the best diaper for sensitive skin, but they fell just short of making the cut. We like that they’re very soft and free from many common irritants, and come packaged with less plastic packaging than other brands. These diapers were passable in our initial tests, absorbing just shy of 1 cup of water before beginning to leak. However, other brands simply were more absorbent.
How We Tested The Best Diapers
For this guide, we did some at-home “lab” testing on all of the 21 different diapers. First, we tried immersion testing. We took each diaper and completely immersed it in water for 10 minutes, weighing it before and after dunking to see how much water was absorbed during that time. We also looked for material breakdown.
Then we laid out a fresh set of diapers and filled them with 2 tablespoons of water at a time, round robin style. Each diaper gave up the ghost eventually by leaking, but some were clear winners by holding out longer.
Of course, we also wanted to know what diapers work the best in real life. The authors’ kids served as the primary testers for this guide, who were 9 months old and 16 months old at the time of testing. We unboxed each—with copious note taking about fastener strength, fabric and fit—before putting them on our children. They wore each for a full day of diaper changes and a full night. We noticed which diapers were more prone to leaking, fraying or otherwise falling apart. Some diapers also struggled to contain poop. We did a lot of laundry.
We also conducted two rounds of the same wearability tests with panels of parents and their kids. Each caregiver filled out a survey after trying each diaper for a day and night with their children. Any winners were kept in the usual diaper rotation for long-term testing. In the first round, the top six diapers were tested by a 10-month-old boy, 4-year-old girl, 22-month-old boy and 4-month-old boy. We tried size 2, 3, 4 and 6 diapers.
In our second round, additional top diapers were tested by a 2-week-old newborn, a 13-month-old girl with sensitive skin and a 2-year-old boy with sensitive skin to determine the best diapers for newborns and the best diapers for sensitive skin.
How To Pick The Best Diaper For Your Child
The best diaper for a newborn to a toddler offers the following traits.
Absorbent
Parents need diapers that don’t leak. After testing many diapers, we can say that this criteria is harder to meet than we expected. But ideally, a diaper should have three absorbent panels along the crotch that slowly soak up liquid and hold at least 1 cup of liquid, ideally more like 2 cups, without making your child soggy. (Sogginess can cause diaper rash, so it’s important to avoid it from a health perspective.)
Secure Fit
Leaks can also be caused by a poor fit. If a diaper doesn’t fit well, the gaps between your child’s legs and the diaper, or around their waist, cause pee to run out and wet their clothes. To get a good fit, you need well-constructed tabs that secure around the child’s waist and stay closed (there’s nothing worse than coming in to find a naked baby in a crib, covered in pee or poo). We found that the more flexible the diaper’s materials were, the better the fit because you could stretch the diaper as needed.
If you love a diaper brand but it starts to leak, this is a sign to go up one more size. Many parents have told us over the years that they size their kids up for overnight diapers in order to better contain nighttime accidents.
Comfortable
A good diaper should be comfortable and feel soft along your child’s thighs and waist and not apt to cause rashes. Some of the cheaper diapers we tried were not soft, and thus caused red marks along my daughter’s legs; this is a no-go. Diapers should also keep your baby’s skin dry to avoid diaper rash.
Secure
Few things are worse than finding your baby naked with a diaper hanging off their leg after a nap. The best way to keep a diaper secure is to pick one with sticky, durable tabs that wrap around your baby’s waist. The cheaper diapers we tried had a tendency to come unfurled, and the best stuck through long naps and outdoor adventures.
Easy To Find
A few of the diapers we researched ahead of putting together the testing panel were out of stock or not easy to buy online. Ideally, a good diaper should be one that you can find (or that arrives at your door via a subscription or delivery service) without significant effort. We prioritized this in our decision-making process.

Frequently Asked Questions (FAQs)
One might think that when buying diapers size 3 means the same exact size in each brand—but we didn’t find that to be true. Where sizing becomes most relevant is when you wrap the rear flaps around your baby’s belly. This is a very good indication of whether or not the diaper size is right: Do the flaps touch one another when wrapped around your baby? If so, it’s too big. Can you see your baby’s belly when those flaps are fully stretched? If yes, the diaper is too small.
Educator Shanna Jonathan also recommends pulling the seam flaps between the baby’s legs up, before you put the diaper on, to prevent leaks. Dr. Carolyn Birbiglia also notes: “Ideally you should be able to fit two finger tips under the waistband without feeling tight constriction.”
“If you are noticing leaks and blowouts regularly, it is time to change diaper sizes even if your little one is still in the weight range for the size you are buying,” says Jonathan.
Birbiglia also recommends watching for red marks on the baby’s legs, hips or groin. These indicate that a diaper is too tight; and if the diaper is closer to their hips than their belly button, or their bottom doesn’t seem quite as covered as it once was, it’s time to size up too.
“The diaper itself should come with size guidelines to help parents choose what size is likely best based on the baby’s weight,” Birbiglia says. We found during testing that you’ll need to size up earlier in some brands (like Honest Company) compared to others.
Diapers should be flexible. Consider tensile strength, which refers to how well a diaper can stretch and contort while maintaining its structural integrity. Once a baby starts to really move, their diaper needs to stretch and move with them or it will either leak or simply fall off. Though this is important throughout the diaper, tensile strength is mostly important in those rear flaps that wrap around your child’s waist. A diaper without good tensile strength might come off more easily; the tabs also tend to rip off the diaper itself when you’re trying to put the diaper on.
“To prevent rash, allow the diaper area to dry completely before putting a clean diaper on,” Jonathan says. “I recommend fanning the area with the clean diaper. I also always apply a thin layer of Aquaphor to their diaper area with each change.”
Birbiglia also recommends changing your child’s diaper as soon as you can, especially after they poop; for young babies, this may mean changing diapers almost every hour. But as your child gets older, diaper changes will become less frequent. When their sensitive skin sits in a soiled diaper, a rash is more likely to occur.
One pro tip: If your baby is prone to diaper rash, look for a fragrance and dye-free option (like Bambo and HealthyBaby). Make sure the diaper is secure, too; a diaper that moves around a lot can cause friction.
Note On Giving Back: After testing diapers for this guide, we donated just over 1,000 diapers to local diaper banks and relief nurseries, including Moms Helping Moms in New Jersey.
