Our Top Pick
Pampers Swaddlers Overnights is the strongest all-round overnight diaper for babies and toddlers who fit sizes 3 through 7.
TL;DR: The Quick Answer
- Best overall: Pampers Swaddlers Overnights (now sold as Pampers ZZZ) absorbed more than 60 ounces in immersion testing without the core breaking apart (Forbes Vetted, 2026).
- Best budget: Luvs Triple Leakguard held 24 tablespoons of liquid before leaking at roughly $0.25 per diaper, about half the price of Pampers or Huggies (Forbes Vetted, 2026).
- Most absorbent tested: Coterie The Diaper held 28 tablespoons before leaking, the highest of 15 styles tested, at a subscription price starting around $95 per month (Coterie, 2026).
- Best for kids over 40 lbs: Goodnites Nighttime Underwear holds 24 ounces of liquid and fits from 28 to 165 pounds, so it covers bedwetting long after diapers stop fitting (Goodnites, 2026).
- Sizing up one size in your regular diaper solves many overnight leaks for less money than switching to a dedicated overnight diaper.

What to Look for in an Overnight Diaper
An overnight diaper needs three things: enough liquid capacity for 10 to 12 hours, a core that stays intact when saturated, and leg cuffs that seal against a sleeping child who rolls. Price per diaper decides whether the upgrade is worth making nightly. Here is the full criteria set used to rank every product below.
Total liquid capacity
An infant who sleeps 12 hours can produce far more urine than a daytime diaper is built to hold, so raw capacity sets the ceiling on dry mornings.
Time to leak under repeated wetting
Real nights involve several separate wettings, not one flood, so a diaper that reabsorbs quickly outperforms one with a high total capacity.
Core stability when saturated
Some diapers release fluff pulp once soaked, which leaves gel beads on your baby's skin and reduces the capacity you paid for.
Leg cuff design
Double or elasticized cuffs are what stop side leaks when a child sleeps on their stomach or side for hours at a time.
Waistband and back pocket
A pocketed or snug back waistband catches the upward leaks that soak pajama tops and crib sheets.
Fit at the size you actually need
A diaper that runs small forces you into the next size, which changes both the cost per diaper and the fit around the legs.
Wetness indicator visibility
An indicator line that runs high up the back tells you whether the diaper is saturated without unswaddling a sleeping baby.
Fragrance and dyes
Fragrance masks odor but can irritate children with eczema or reactive skin, so it is a preference worth deciding on before you buy in bulk.
Bulk and mobility
Thicker cores absorb more but restrict crawling and rolling, which matters if your child moves constantly in the crib.
Size range ceiling
Most overnight diapers stop at size 7, so families with older toddlers need to know when the brand runs out of sizes.
Cost per diaper
Overnight diapers are used once per night rather than six times a day, so the nightly premium is smaller than the sticker price suggests.
Availability and restock speed
Subscription-only brands cannot be replaced at 9 p.m. on a Sunday, which matters more than most buying guides admit.
In-Depth Reviews: 7 Overnight Diapers Compared
Each pick below is rated on tested absorbency, fit, materials and price per diaper. Independent testing data comes from Forbes Vetted, which put 15 overnight styles through immersion and leak tests in 2026.
#1 · Overall performance
Pampers Swaddlers Overnights (Pampers ZZZ)
Best Overall Overnight Diaper
Pampers Swaddlers Overnights is the strongest all-round overnight diaper for babies and toddlers who fit sizes 3 through 7. It combines high capacity with a fit that runs true to size, so most families can buy their normal size and stop there.
Key Features
- OVERNIGHT DIAPERS: Pampers are the #1 Brand*. For Sleep. (*Based on Nielsen volume sales L52W)
- EXTRA ABSORBENT: Made with 50% more absorbent zones vs ordinary diapers,* Pampers ZZZ baby diapers help keep baby's skin...
- BLOWOUT & LEAK PROTECTION: Pampers ZZZ feature a blowout barrier and all-around LeakGuard for up to 100% blowout and lea...
Quick Specs
- Size Range: Size 3-7 (16-41+ lbs)
- Price Per Diaper: $0.41-$0.60
- Fragrance: Yes
- Standout Spec: 60+ oz absorbed, core stayed intact
In Forbes Vetted’s 10-minute immersion test, this diaper soaked up more than 60 ounces of water and kept its absorbent core intact, with no fluff pulp release (Forbes Vetted, 2026). Core stability matters as much as raw capacity, because a core that separates dumps gel onto your baby’s skin.
Testers reported that liquid spreads across the whole pad instead of pooling in one spot, which keeps a single saturated patch from pressing against the skin for hours. Pampers rates the diaper for up to 12 hours and says it has 50% more absorbent zones than its standard Swaddlers (Pampers, 2026).
Sizing runs from size 3 (16-28 lbs) through size 7 (41+ lbs), so it covers roughly 6 months through the end of diapering (Pampers, 2026). The adhesive tabs reattach cleanly, which helps when a toddler tries to wriggle out mid-change.
The scent is the real drawback. One Forbes tester said she could smell the diaper on her child from three feet away (Forbes Vetted, 2026). If your child has eczema or reactive skin, the fragrance and dyes here are a reason to look at Coterie instead.
Note that Pampers has moved this product to “Pampers ZZZ” packaging at most retailers. The product is the same; the box art changed, which causes confusion when reordering.
Pros
- Held more than 60 ounces in immersion testing without the core breaking apart.
- Spreads liquid evenly across the pad rather than saturating one area.
- Runs true to size, so you do not need to buy up a size to get 12 hours.
- Stocked at nearly every grocery store, pharmacy and big-box retailer in the US.
Cons
- The fragrance is strong enough to notice from several feet away.
- Costs roughly $0.41 to $0.60 per diaper depending on pack size and retailer.
- Uses dyes in the backsheet prints, which some sensitive children react to.
Best for
Babies 6 months and older who leak through standard diapers and whose skin tolerates fragrance.
Not ideal for
Children with eczema, known fragrance sensitivity or a history of contact reactions.
#2 · Fragrance-free mainstream
Huggies Overnites
Best Fragrance-Free Option You Can Buy Anywhere
Huggies Overnites is the best fragrance-free overnight diaper sold in mainstream stores. It matched Pampers on absorbency in lab testing and skips the fragrance, lotions and elemental chlorine that make some parents rule Pampers out.
Key Features
- Huggies Overnites Size 3 Diapers: 66 overnight diapers, size 3 (16-28 lbs), packaging may vary
- #1 Best-Selling overnight diaper* (*52 weeks ending 9/13/2025)
- Designed Differently for Nighttime Protection: Overnites baby diapers have extra absorbency for uninterrupted sleep
Quick Specs
- Size Range: Size 3-7 (16-41+ lbs)
- Price Per Diaper: $0.37-$0.76
- Fragrance: No
- Standout Spec: Pocketed back waistband
The diaper absorbed more than 60 ounces during the same 10-minute immersion test that Pampers passed (Forbes Vetted, 2026). Huggies rates it for up to 12 hours and builds it with a DryTouch liner, a curved fit, double grip strips and a pocketed back waistband (Huggies, 2026).
Fit is where it slipped. Two of the Forbes testers had multiple leaks with Overnites, and the diaper runs slightly small (Forbes Vetted, 2026). Huggies itself recommends sizing up from your daytime diaper because the Overnites fit is tapered (Huggies, 2026).
Materials are cleaner than the Pampers equivalent. Huggies makes Overnites without fragrance, lotions, parabens, phthalates, elemental chlorine and natural rubber latex, and the diaper is hypoallergenic (Huggies, 2026). The wetness indicator turns from yellow to blue.
Sizes run from 3 (16-28 lbs) to 7 (41+ lbs), and pricing lands between roughly $0.37 and $0.76 per diaper depending on pack size (Walmart, Amazon and H-E-B listings, September 2026). Buying the 132-count club pack is where the price drops meaningfully.
Pros
- No fragrance, lotions, parabens, phthalates or elemental chlorine.
- Matched the top performer on total liquid absorbed in immersion testing.
- Pocketed back waistband targets the upward leaks that soak crib sheets.
- Widely stocked, including club-size packs at Sam's Club and Costco-style volumes.
Cons
- Runs small, so many families need to buy one size up.
- Leaked repeatedly for two of the testers in independent panel testing.
- Small jumbo packs push the per-diaper cost past $0.70.
Best for
Babies who roll or sleep on their stomach, and families avoiding fragrance without paying subscription prices.
Not ideal for
Anyone buying in small pack sizes, where the cost per diaper stops making sense.
#3 · Sensitive skin, heavy wetters
Coterie The Diaper
Best for Sensitive Skin and Heavy Wetters
Coterie The Diaper absorbed more liquid before leaking than any other product in independent testing, and it does so without fragrance, dyes or chlorine bleach. It is the pick for children whose skin reacts to mainstream diapers.
Key Features
- THE BABY DIAPERS: Minimize leaks, blowouts, and the cause of moisture-related diaper rash. Coterie Diapers can absorb ov...
- THE BABY WIPES: Coterie unscented baby wipes are made with 99% water and 100% plant-based fibers. Each wipe is up to 30%...
- DESIGNED FOR NEWBORN + SENSITIVE SKIN: Our sensitive baby wipes and diapers are dermatologist tested, hypoallergenic, an...
Quick Specs
- Size Range: Newborn-7 (up to 41+ lbs)
- Price Per Diaper: $0.46-$0.90
- Fragrance: No
- Standout Spec: 28 tbsp before leaking, highest tested
In the Forbes leak test, where water was added two tablespoons at a time until failure, Coterie took 28 tablespoons before leaking – the highest result among 15 styles (Forbes Vetted, 2026). Coterie’s own lab testing puts capacity above 16 ounces in size 4, with up to 12-hour protection (Coterie, 2026).
Coterie does not sell a separate overnight diaper. The company’s position is that one diaper should handle day and night, since infants do not have day-night sleep rhythms from birth (Coterie, 2026). In practice that means you are buying a premium daytime diaper and using it overnight.
The brand says The Diaper is made without more than 200 chemicals, including fragrance, lotion, latex, dyes, parabens, phthalates, chlorine bleach and VOCs (volatile organic compounds) (Coterie, 2026). Testers also noted the wetness indicator runs higher up the back than competitors, so you can check saturation without a full unwrap.
Price is the barrier. Subscriptions start around $95 per month, working out to roughly $0.46 per diaper in size 3 and higher in larger sizes (Coterie, 2026; Forbes Vetted, 2026). Using Coterie only at night, instead of around the clock, keeps the monthly spend near $30.
Pros
- Held the most liquid of any diaper in independent leak testing.
- Made without fragrance, dyes, chlorine bleach and more than 200 other chemicals.
- Wetness indicator extends further up the back for easier overnight checks.
- Sizes run from newborn through size 7, so one brand covers the full diapering span.
Cons
- Roughly two to three times the per-diaper cost of Huggies or Pampers.
- Subscription-first model means no late-night restock at a local store.
- No dedicated overnight version, so heavy wetters may still need a size up.
Best for
Children with eczema or reactive skin, and heavy wetters where nothing else lasts the night.
Not ideal for
Families on a tight diaper budget or anyone who prefers to buy in person.
#4 · Budget
Luvs Triple Leakguard
Best Budget Overnight Diaper
Luvs is the best value overnight option, at roughly $0.25 per diaper – about half the cost of Pampers and Huggies overnight lines. It also outperformed most dedicated overnight diapers in leak testing.
Key Features
- Triple Leakguards with 3 absorption areas help keep baby's skin dry
- Nightlock Technology locks away wetness for up to 12 hours of overnight protection
- Super soft on baby's skin for a comfy feel
Quick Specs
- Size Range: Newborn-7 (up to 41+ lbs)
- Price Per Diaper: ~$0.25
- Fragrance: Light
- Standout Spec: 24 tbsp before leaking at half the price
Luvs held 24 tablespoons of water, or a cup and a half, before leaking in Forbes Vetted’s incremental leak test (Forbes Vetted, 2026). Only Coterie held more. Across a panel of children aged 16 months to 3 years, Luvs never leaked, including on 12-hour nights.
Luvs is not marketed as an overnight diaper. The brand positions it for day and night use, which is why it costs less than products with “overnight” on the box. For many families that distinction is the whole savings.
The construction is thin and lightweight rather than plush, which makes it a better fit for warm rooms, summer months and travel. Several testers with eczema-prone children reported no skin irritation during testing (Forbes Vetted, 2026).
Two caveats. The diaper runs small, so sizing up is common, and it has a light fragrance plus dyes in the backsheet prints. Sizes run from newborn (up to 10 lbs) through size 7 (41+ lbs).
At $0.25 per diaper, the annual math matters: US families spend about $100 a month per child on diapers, while the median family can only afford about $65 (Urban Institute analysis of NDBN Diaper Check 2024).
Pros
- About half the per-diaper price of name-brand overnight diapers.
- Held 24 tablespoons before leaking, second only to Coterie in testing.
- Thin build works better than plush diapers in hot rooms and while travelling.
- Full size range from newborn to size 7.
Cons
- Runs small, so most families size up one step.
- Has a light fragrance and printed dyes.
- Not sold as an overnight product, so absorbency claims are not night-specific.
Best for
Budget-conscious families, hot climates and parents who want one diaper for day and night.
Not ideal for
Very heavy wetters who already leak through a sized-up standard diaper.
#5 · Softness for the price
Millie Moon Overnight
Best Softness for the Price
Millie Moon Overnight sits between mass-market and premium diapers on both feel and cost. It is the pick for parents who want a soft, low-irritant diaper without moving to a subscription brand.
Key Features
- Size 4 count 58. overnight diapers All-Night Absorbency for over 12 hours of leak protection. Absorbs up to 15% more liq...
Quick Specs
- Size Range: Size 3-6
- Price Per Diaper: $0.71-$1.12
- Fragrance: No
- Standout Spec: 15% more capacity than its daytime diaper
Millie Moon rates the overnight version for more than 12 hours and says it absorbs up to 15% more liquid than its standard Luxury diaper, using what the brand calls an EverDry layer (Millie Moon, 2026). The wetness indicator turns purple when the diaper is full.
The diaper is made without lotions, latex, fragrance and elemental chlorine (Millie Moon, 2026). Reviewers consistently rate softness above brands at the same price, which is the brand’s main selling point over Huggies.
Fit is the variable to watch. Independent reviewers report that Millie Moon runs big, so children between sizes usually do better sizing down rather than up (Reviewed, 2026). That is the opposite of the advice for Huggies and Luvs.
Pricing swings widely by pack. Walmart listings in September 2026 ranged from about $0.71 per diaper in a size 4 58-count to $1.12 per diaper in a size 6 42-count. Buy the largest pack available or the value case disappears.
Availability is narrower than the mainstream brands. Millie Moon sells mainly through Walmart and Target, and the overnight line is newer than the Luxury line, so it carries fewer verified reviews.
Pros
- Rated for 12-plus hours with 15% more capacity than the brand's daytime diaper.
- Made without fragrance, lotions, latex and elemental chlorine.
- Softer hand-feel than mass-market diapers at a similar price.
- Purple wetness indicator is easy to read in low light.
Cons
- Runs big, which can cause gaps at the legs on slimmer babies.
- Per-diaper cost passes $1.00 in smaller packs.
- Sold at fewer retailers than Pampers and Huggies.
Best for
Parents who want premium softness and clean materials without a subscription.
Not ideal for
Slim babies who already have gaps at the leg cuffs, and anyone buying small packs.
#6 · Plant-based, low bulk
The Honest Company Overnight
Best Low-Bulk Plant-Based Diaper
The Honest Company Overnight is the best choice for parents who want plant-based materials and a slim profile. Honest built this version on a thinner core that adds capacity without the bulk of a traditional overnight diaper.
Key Features
- Improved and ready to snooze! Now in new gender-neutral prints and with a wetness indicator so you know when it’s time f...
- Clean Conscious Overnight Diapers are designed with safe plant-based materials and sustainable fluff pulp that’s respons...
- Night Absorb Core: Super absorbent material with advanced leak protection to help keep your baby’s diaper dry all night ...
Quick Specs
- Size Range: Newborn-7
- Price Per Diaper: $0.39-$0.77
- Fragrance: No
- Standout Spec: Ultra-thin core, 20% added capacity
Honest states the ultra-thin core absorbs faster and adds up to 20% more capacity than its standard diaper, without extra bulk (Honest, 2026). Moisture barrier cuffs run along both legs to block side leaks and blowouts.
Materials are the reason most people choose this brand. Honest makes the diaper without chlorine or bleach processing, latex, synthetic fragrances and lotions, and sources its fluff pulp from sustainably managed forests (Honest, 2026).
Absorbency does not lead the category. In independent testing, Honest’s training pants soaked up a lot of water in immersion but leaked for every tester during real wear (Forbes Vetted, 2026). Treat this as a good diaper for average wetters rather than a solution for a child who soaks through everything.
Pricing runs roughly $0.39 to $0.77 per diaper depending on pack and retailer, which puts it above Huggies and below Coterie. Club boxes at Walmart are the cheapest route.
The design range is the tie-breaker for many buyers, since Honest rotates seasonal prints across its overnight line while most competitors run a single character design.
Pros
- Thin core delivers overnight capacity without a bulky fit.
- No chlorine processing, latex, synthetic fragrance or lotions.
- Moisture barrier cuffs on both legs target side leaks.
- Plant-based positioning with fluff pulp from sustainably managed forests.
Cons
- Absorbency trails Coterie, Pampers and Luvs in independent testing.
- Related Honest products leaked for all testers in panel testing.
- Costs more than Huggies for less tested absorbency.
Best for
Average wetters whose parents prioritise plant-based materials and a slim fit.
Not ideal for
Heavy wetters and 12-hour sleepers who need maximum capacity.
#7 · Kids over 41 lbs, bedwetting
Goodnites Nighttime Underwear
Best for Kids Who Have Outgrown Size 7
Goodnites is the answer once your child passes 41 pounds and runs out of diaper sizes. It fits from 28 to 165 pounds, holds 24 ounces of liquid, and looks like underwear rather than a diaper (Goodnites, 2026).
Key Features
- GoodNites Girls' Nighttime Bedwetting Underwear: 34 (2 packs of 17) overnight underwear for girls, size large; fits chil...
- Confidence for kids at night: Helps keep kids dry; GoodNites bedwetting underwear for girls provides up to 100% leak fre...
- Extra protection where girls need it: Our bedwetting underwear provide unbeatable leak protection** to help keep pajamas...
Quick Specs
- Size Range: 28-165 lbs
- Price Per Diaper: $0.72-$1.28
- Fragrance: No
- Standout Spec: 24 oz capacity, FSA/HSA eligible
Sizing runs XS (28-43 lbs), S/M (43-68 lbs), L (68-95 lbs), XL (95-120 lbs) and XXL (120-165 lbs), which maps to roughly ages 3 through the teen years (Goodnites, 2026). No diaper brand comes close to that range.
Goodnites rates capacity at 24 ounces, described as three 8-ounce bottles of saline, using what the brand calls Quicksorb protection and double leg barriers (Goodnites, 2026). The material is odor-absorbing and hypoallergenic.
Bedwetting is far more common than most parents assume. About 15% of children still wet the bed at age 5, dropping to roughly 4% by age 8, and it resolves on its own at about 15% per year (StatPearls, NCBI Bookshelf, 2024). Nighttime underwear is a management tool, not a treatment.
One testing caveat: Goodnites released a large amount of fluff pulp during a 10-minute immersion test and was cut before the wear-testing round (Forbes Vetted, 2026). In normal use the product is not submerged, but it is a fair signal about core stability under heavy saturation.
Goodnites is FSA and HSA eligible in the US, which effectively discounts it for families with those accounts (Goodnites, 2026). Pricing runs about $0.72 to $1.28 per unit depending on pack size.
Pros
- Fits from 28 to 165 pounds, far beyond where diaper sizing stops.
- Holds 24 ounces, the highest rated capacity in this guide.
- Underwear-style design is discreet under pajamas for school-age kids.
- FSA and HSA eligible, which lowers the real cost for many families.
Cons
- Released fluff pulp under heavy saturation in lab testing.
- Costs up to $1.28 per unit in small packs.
- Pull-on design cannot be adjusted for fit the way tabbed diapers can.
Best for
Potty-trained children who still wet at night, and any child over 41 pounds.
Not ideal for
Babies and young toddlers who still need a tabbed diaper for lying-down changes.
How to Stop Overnight Diaper Leaks Without Switching Brands
Most overnight leaks are a fit problem, not a capacity problem. Before buying a new brand, size up one step in the diaper you already use and re-check the leg cuffs. That single change resolves a large share of nighttime leaks at no extra cost.
Should You Size Up for Overnight Diapers?
Yes, in most cases. Jennifer Saxton, founder and CEO of Tot Squad, advises going one size larger when a diaper leaks at night, because the next size up contains more absorbent material and regular diapers cost less than overnight-specific ones (Forbes Vetted, 2026). Huggies gives the same advice for its own Overnites line, which has a tapered fit (Huggies, 2026).
Two exceptions apply. Millie Moon runs big, so sizing up creates leg gaps. And a diaper that is too large leaks at the thighs even when the core is barely used.
Do Overnight Diapers Actually Hold More Than Regular Diapers?
Usually, but not always. Overnight diapers typically have extra material in the absorbent core and better leak guards at the leg cuffs, according to Dr. James Treat, a pediatric dermatologist at the Children's Hospital of Philadelphia (Forbes Vetted, 2026). The gap is narrower than marketing suggests: Luvs, a standard diaper, out-absorbed several dedicated overnight products in testing.
Are Diaper Booster Pads Worth It?
Booster pads are inserts that add capacity to a diaper you already own. Forbes Vetted does not recommend Sposie Booster Pads, citing mixed feedback from online reviewers and from the subject-matter experts it consulted (Forbes Vetted, 2026). If you try them, watch for bunching, which creates a channel for leaks rather than blocking them.
Is It Safe to Leave a Baby in One Diaper for 12 Hours?
It is safe if the diaper keeps urine away from the skin and there is no stool in it. Most diaper rash happens when waste is held against the skin, per Dr. Treat (Forbes Vetted, 2026). Diaper dermatitis affects an estimated 25% to 50% of babies depending on age, with the highest rates between 9 and 12 months (Journal of Tissue Viability, 2022). Change a soiled diaper immediately, even overnight.
Frequently Asked Questions About Overnight Diapers
What is the best overnight diaper?
Pampers Swaddlers Overnights is the best overall overnight diaper for babies in sizes 3 through 7, based on absorbency, core stability and true-to-size fit. Coterie The Diaper holds more liquid but costs two to three times as much. Luvs offers the best price-to-performance ratio at roughly $0.25 per diaper.
At what age do babies need overnight diapers?
Most babies start needing one around 4 to 6 months, when night sleep consolidates into long stretches. The American Academy of Sleep Medicine recommends 12 to 16 hours of sleep per 24 hours for infants 4 to 12 months and 11 to 14 hours for ages 1 to 2 (AASM, 2016). Those stretches are longer than a standard diaper is designed to cover.
How many overnight diapers will I use per month?
Roughly 30 to 40, since overnight diapers are used once per night with occasional changes for stool. At $0.50 per diaper, that is about $15 to $20 a month. US families spend about $100 a month per child on diapers overall, and half of families with young children report struggling to afford enough (NDBN Diaper Check, 2026).
What is the difference between overnight diapers and regular diapers?
Overnight diapers have more absorbent material in the core and stronger elastic leak guards at the leg openings (Forbes Vetted, 2026). They are built for a single 10 to 12 hour wear rather than a 2 to 3 hour wear. They also cost more per diaper, which is why sizing up a regular diaper is worth trying first.
Can overnight diapers cause diaper rash?
Not by themselves. Rash comes from urine and stool sitting against the skin, which raises skin pH and overhydrates the outer skin layer. A high-capacity diaper that wicks moisture away reduces that contact. Fragrance and dyes are a separate issue and can cause an irritant reaction in sensitive children (Forbes Vetted, 2026).
Are expensive overnight diapers worth the money?
Only for specific situations: heavy wetters, eczema-prone skin, or after cheaper options have already failed at a sized-up fit. Coterie held the most liquid in testing, but Luvs held nearly as much at a fifth of the cost. Start cheap, move up only if you are still stripping the bed.
What should I use once my child outgrows size 7 diapers?
Goodnites Nighttime Underwear, which fits from 28 to 165 pounds. Pull-on alternatives include Coterie The Pant, which fits size 3 (14-24 lbs) through size 6 (33-62 lbs) at about $0.59 per unit in size 4, and Pampers Ninjamas at about $0.60 per unit in small/medium, 38-70 lbs (Forbes Vetted, 2026).
Final Verdict
Pampers Swaddlers Overnights is the best overnight diaper for most families: it held more than 60 ounces without its core breaking down, fits true to size, and is stocked everywhere. Skip it if your child reacts to fragrance and choose Huggies Overnites or Coterie instead.
For value, Luvs Triple Leakguard is the smarter first move. It held 24 tablespoons before leaking at about $0.25 per diaper, which beats most dedicated overnight products on cost per dry night. Buy one pack sized up from your daytime diaper before you spend more.
Once your child passes 41 pounds, Goodnites is the only realistic option, and its 24-ounce capacity and 28 to 165 pound range mean you will not be shopping again for years.
