Pros

Highly absorbent and soaks up liquid quickly, holding up well for naps and longer stretches between changes.
Durable enough to last through multiple children; one person reported 3.5 years of use across two kids with a top-load washer.
Gets softer with each wash and cotton retains less odor over time compared to synthetic alternatives.
Trim enough to fit inside pocket diapers or covers when trifolded, without adding bulk.

Cons

Sizing runs large for smaller babies; a few people found the small size too big for newborns well within the stated weight range.
Stitching durability is inconsistent; several people noticed fraying or threads coming undone within months of regular use.
Less soft than bamboo inserts out of the package, though softness improves after repeated washing.

Prefold cloth diapers are flat, layered rectangles of cotton that you fold around the baby and secure with pins or a fastener, trifold into a diaper cover, or stuff into a pocket diaper as an insert. They require a separate waterproof cover to work as a complete diapering system.
Unlike some prefolds from larger children's clothing brands that use polyester filling sandwiched between two cotton layers, these are cotton through all layers. All-cotton construction tends to be more absorbent and avoids the ammonia odor buildup that can happen with synthetic fills.
OsoCozy offers both "Traditional" (longer) and "Better Fit" (shorter) cuts. Traditional prefolds work well if you want to pin or fasten the diaper directly on the baby. Better Fit prefolds are sized to trifold neatly into a cover without extra bulk from folding over excess length.
New prefolds arrive stiff and not yet absorbent. They need 3 to 5 hot washes before the natural cotton oils are stripped and the fabric actually absorbs liquid, so plan to prep them well before the baby arrives.
Unbleached cotton gives these non-toxic cloth diapers a natural ivory color rather than bright white. After washing and drying on high heat, the fabric quilts up and softens considerably.
Sold in packs of six, so most families need several packs to build a full rotation. A common recommendation is at least 18 prefolds on hand to wash every 3 to 4 days.

Pros

Works well as a booster layer inside cloth diapers for extra absorbency, especially overnight.
Easy to clean and wicks moisture effectively when paired with other inserts.

Cons

Shrinks noticeably in the dryer; stretching them back out restores the size, but it's an extra step.
The three-layer version is very thin and may not provide enough absorbency on its own.
Absorbency is inconsistent; one person found even the six-layer version didn't absorb at all.

These are liner inserts, not standalone diapers. You place them inside a cloth diaper cover or pocket diaper to add absorbency, and they're compatible with most diaper pant styles.
Sold as a set of 10, which is enough to rotate through a day's worth of changes before washing.
Available in a three-layer or six-layer version; the thicker option adds more absorbency for heavy wetters or overnight use.
The edges are reinforced with stitching to hold up through repeated washing without fraying, which is a common failure point for non-toxic cloth diaper inserts made from natural fibers.
Cotton construction means they can be machine washed and reused, keeping them in the rotation alongside your existing cloth diaper setup.

Pros

The outer shells are well-made and hold up better than many competing cloth diaper covers.
Two-size system means less bulk on the baby compared to one-size-fits-all designs.
Easy to launder and stains come out with sunning or a periodic bleach cycle.
Double as swim diapers, adding extra utility beyond everyday use.
Simple snap-on design that works well for people new to cloth diapering.

Cons

The cotton inner doesn't wick moisture away from skin, so it feels noticeably wet at change time; most people add extra liners or switch to disposables overnight.
Takes a long time to dry because the inner is sewn as one piece rather than separating out.
The outer shell can hold a urine smell after a few liner changes even with wiping between swaps.
A few people noticed stitching starting to unravel after only a short period of regular use.

Two-piece system: a fitted cotton Inner handles absorbency, and a waterproof Outer snaps over it for containment. You swap the Inner at each change but can reuse the Outer multiple times before washing, so you need far fewer covers than liners.
The Outer doubles as a reusable swim diaper on its own (just skip the Inner), which is a practical bonus if you're already investing in the system.
Each Inner has a "butterfly" layered core, meaning the absorbent material is shaped to stay trim between the legs while still concentrating thickness where it's needed. That layered structure also helps water and detergent penetrate during washing.
Two rows of waist snaps let you size the waist and leg openings independently, so the fit works on babies with different proportions (big belly and skinny legs, or the reverse).
Esembly started as a Brooklyn diaper laundering service in 2009, washing 15,000+ cloth diapers a week for a decade before designing their own system. The product line grew directly out of that hands-on laundry science and feedback from thousands of families.
For families researching non-toxic diapers, the bundle is a low-commitment way to try cloth: three Inners and one Outer is enough to test the system part-time before building a full stash.

Pros

Soft texture that fluffs up nicely after a couple of washes.
Single-layer design dries much faster than multi-layer inserts, which also makes handwashing easy.
Stains release well and hair comes off without effort.

Cons

Absorbency is limited; one person reported needing to change roughly every hour.
The tan color bled noticeably during the first wash, which raised concerns about dye for at least one person (26 others found this helpful).

Flat diapers are the simplest style of cloth diaper: a single layer of fabric you fold yourself to fit your baby. The fold you choose determines the fit, so one diaper works from newborn through toddler sizes without needing different products as your baby grows.
Because you're folding a single layer of fabric (not multiple sewn-together layers), flats rinse cleaner in the wash and dry significantly faster than prefolds or fitted cloth diapers. They can even be line-dried in humid climates.
You'll need a few extras to make these work: a fastener (snappis or pins) to hold the fold in place, plus a waterproof diaper cover over the top. Alternatively, you can skip the folding entirely and just pad-fold them into a rectangle to lay inside a cover or stuff into a pocket diaper.
Muslin weave is softer and more pliable than the birdseye weave OsoCozy also offers, which can make it easier to get a snug fold around smaller babies.
As non-toxic cloth diapers go, flats are about as straightforward as it gets: one piece of unbleached cotton, no dyes, no waterproofing treatments, no snaps or elastics. The tradeoff is a learning curve with folding.
OsoCozy uses only cotton across its diaper line rather than synthetic or blended fabrics, and has been a dedicated cloth diaper brand (not a side product from a larger baby company) for years.

It's a two-part system: an absorbent inner diaper goes against baby's skin, and a waterproof outer cover goes over it. Three inner diapers and one cover come in the bundle, plus an extra liner for overnight or heavy wetters.
The inner diapers have adjustable snap buttons so each one spans a range of sizes rather than being single-use at one weight. You'll get more wear out of fewer diapers as baby grows.
The outer cover doubles as a swim diaper, which is a practical bonus if you're already investing in the cloth system.
For parents exploring non-toxic diapers, cloth is the most direct way to reduce chemical contact since the layer against skin is unbleached cotton rather than synthetic materials with absorbent polymers.
HealthyBaby also makes disposables and actively encourages "combo diapering," using cloth at home and disposables on the go, so the bundle is designed to work alongside their other products rather than replace them entirely.
Pre-washing the inner diapers and liners before first use is necessary to get full absorbency and proper fit; they won't perform well straight out of the package.

Unbleached Organic Cotton Birdseye Flat Diapers

Birdseye flats are single-layer cotton squares you fold yourself before placing inside a waterproof diaper cover. The folding method you choose (origami, kite, pad fold, etc.) lets you customize absorbency and fit as your baby grows, so one size works from birth to potty training.
Part of Buttons' all-in-two system: the flat acts as the absorbent insert, and the wipeable cover can be reused across multiple changes before washing. You'll need a separate cover to use these.
Flats dry faster than prefolds or multi-layer inserts, which matters if you're line-drying or doing laundry frequently. The tradeoff is a longer diaper change since you're folding each time.
Buttons recommends 3 to 4 wash-and-dry cycles before first use to remove natural cotton oils and bring the fabric to full absorbency. Skipping this prep step can cause leaking.
For parents building a non-toxic cloth diapers stash on a budget, flats are typically the most affordable insert option. Buttons is a family-run operation based in Idaho; their products are manufactured in China.

Pros

Absorbent and reliable, especially for overnight use with an added insert.
Washes well and holds up over multiple wash cycles.
Fits well on larger or average-sized babies.

Cons

Velcro fasteners (rather than snaps) can snag on other items in the wash.
Cut is wide across the seat, so it may not work well for slim or narrow-bottomed babies.
Takes a long time to dry; air drying in particular leaves the cotton stiff and rough.
Bulkier than some alternatives, which is more noticeable during daytime use.

Fitted cloth diapers need a separate waterproof cover over them to prevent leaks. The fitted shape with elastic at the legs and waist handles containment; the cover you pair it with handles moisture-proofing.
Constructed with three full-width layers of organic birdseye cotton plus multiple center pad layers of organic flannel. Birdseye weave is the same material used in traditional prefold and flat diapers for over a century, chosen for its absorbency and durability.
Snap closures instead of hook-and-loop (Velcro), so there's nothing to snag other laundry or wear out over time.
Sold individually rather than in multi-packs, which lets you mix sizes or try one before committing. Most competing non-toxic cloth diapers in this style are sold in bundles.
Sewn in the U.S. by stay-at-home moms and grandmothers, not factory-produced. OsoCozy positions itself specifically around keeping small-scale cloth diapering alive.
Unbleached cotton needs 3 to 5 prewashes before it becomes fully absorbent, so plan for some prep time before first use.

How to Swap to Non-Toxic cloth diapers:

Here's how to swap to non-toxic cloth diapers:

What to know about cloth diapers

Cloth diapers sit directly against your baby's skin for hours at a time, covering a large and sensitive area of the body. Because of this constant, prolonged contact, the materials they are made from and how they are finished matter.

Welpr focuses on the fabrics used, whether they are organic or conventionally grown, and what dyes, finishes, or waterproofing treatments are applied.
Babies have thinner, more absorbent skin than adults, so material quality in diapers deserves extra attention.

Review the cloth diapers you already have

Check the labels or product listings for your current cloth diapers. Look at what fibers they are made from and whether the manufacturer mentions any certifications or details about dyes and finishes.

Look for terms like "organic cotton," "GOTS certified," or "OEKO-TEX Standard 100" — these indicate the fabrics have been tested or produced with fewer chemical treatments.
Start by reviewing the diapers your baby wears most often or overnight, since those have the longest skin contact.

Use your current cloth diapers more safely

If you are not ready to replace your cloth diapers right away, a few simple steps can reduce what comes in contact with your baby's skin. New diapers especially can carry residues from manufacturing.

Wash new cloth diapers at least 3–4 times before first use to help remove residual dyes, finishes, and fabric treatments.
Use a non-toxic laundry detergent and skip fabric softeners or dryer sheets, which can leave synthetic coatings on the fabric.

Choose cleaner cloth diapers

When shopping for new cloth diapers, prioritize ones made from certified organic natural fibers without chemical treatments. Simple, undyed or naturally dyed options tend to have fewer added finishes.

Look for diapers made with GOTS-certified organic cotton, hemp, or bamboo for the layers that touch skin, and be cautious of vague claims like "natural" or "eco-friendly" without a recognized certification to back them up.
