Baby cloth diaper guide
Cloth diapering a baby doesn't have to be complicated. At its core it's three things — a waterproof cover, an absorbent layer, and a wash routine that keeps them clean. This guide walks through how to pick the right system for a newborn, an infant, a toddler, or a potty-training kid, which EcoAble products fit each stage, and how to build a stash that actually works day to day.
The short version: if you're just starting, a starter kit for daytime plus an overnight set for nighttime covers the core system. From there you add inserts for capacity, boosters for heavy wetters, and swim or potty training options as the baby grows. Full-time cloth diapering for one baby typically needs 18–24 diapers in rotation with laundry every 2–3 days.
Where to start
If you've never used cloth diapers before, don't order a stash of 24 diapers on the first purchase. Fit varies between babies, and what works brilliantly for one family doesn't always work for another. The most reliable approach is a small starter purchase to test fit and comfort, then scale up once you know the system works for your baby.
What you need by age and stage
Different stages need different products. Most of the system stays the same — it's the absorbency, quantity, and specialty pieces that change.
Daytime system
A daytime cloth diaper has three parts: a waterproof outer cover, an absorbent layer, and something that wicks moisture away from baby's skin. The simplest system uses a cover with a snap-in insert — one garment goes on at a time, easy to change.
EcoAble Cloth Diaper Starter Kit
The Starter Kit is the easiest entry point: one waterproof cover plus three inserts, sized for 10–35 lbs. Enough to test the system for 2–3 days of daytime use before ordering more.
- Adjustable cover fits from infant to toddler sizes
- Three snap-in rayon inserts included
- Soft PUL outer — no plastic crinkle
EcoAble Baby Heavy Duty Diaper Cover
The Heavy Duty Cover with Leg Gussets is the standalone version of the cover in the starter kit. Leg gussets add a second barrier against leaks — particularly useful for newborns with runny breastfed poops, and for heavy wetters at any age.
A no-gusset version is available on Final Sale at a lower price if you don't need the extra barrier.
If a cover is only wet (not soiled), wipe it clean and let it air dry — then reuse it with a fresh insert. Most families get 2–3 uses out of a cover before it needs to go in the wash pile. This is why a daytime stash doesn't need one cover per change.
Nighttime system
Overnight is the hardest test for any diaper — longer wear (often 10–12 hours), higher output, and a baby who moves in sleep. Daytime diapers usually can't handle this without leaking. Nighttime needs a dedicated system with more absorbency and all-around coverage.
Overnight Cloth Diaper Set
The Overnight Set is the bundled nighttime solution: a fitted diaper plus a waterproof cover, sized to work together from 10–35 lbs. This is the starting point for overnight cloth diapering.
EcoAble Baby Hemp Night Fitted Cloth Diaper
The Hemp Night Fitted is the absorbent layer sold on its own. Hemp holds significantly more liquid than microfiber or cotton of the same thickness, which is why it's the go-to overnight fabric. Use with a waterproof cover.
EcoAble Baby Stay-Dry Hemp Night Fitted Cloth Diaper
The Stay-Dry Hemp Night Fitted is the same hemp absorbent core but with a fleece layer against baby's skin. The fleece wicks moisture away, so baby feels dry even when the diaper is holding a lot of liquid. This matters most for babies who wake up fussy when they feel wet.
Disana Baby Fitted Cloth Diaper
The Disana Fitted is a traditional tie-front fitted diaper in 100% organic cotton. Simpler construction than snap fitteds and fits very snugly thanks to the ties — some parents prefer it for that reason. Also available as a set with booster pads.
Pocket and all-in-one diapers have absorbency concentrated down the middle. Babies who sleep on their side or stomach roll toward the edge of the absorbent area, which can leak before the center catches it. Fitted diapers are absorbent all the way around the body — including the sides — which solves this. That's why every nighttime setup on this page uses a fitted diaper, not a pocket.
Choosing a cover: PUL vs wool
The cover is the waterproof layer. Two materials do this job well and work differently — modern synthetic PUL, and natural merino wool. Most families use PUL; some switch to wool for overnights or for skin sensitivities.
| PUL covers | Wool covers | |
|---|---|---|
| Examples | EcoAble Heavy Duty | Disana Wool, Reiff Overnight Wool |
| Waterproofing | Fully waterproof PUL laminate | Water-resistant via natural lanolin |
| Breathability | Breathable, but less than wool | Very breathable — naturally temperature-regulating |
| Washing | Regular machine wash with diapers | Hand wash only; lanolize every few weeks |
| Between-change reuse | Wipe and reuse 2–3 times | Air dry between uses; can last weeks between washes |
| Cost | Lower upfront | Higher upfront, but needs fewer covers in rotation |
| Best for | Daytime, newborns, families who want simple washing | Overnights, skin sensitivities, minimalist stashes |

Inserts and boosters
Inserts are the absorbent layer that goes inside the cover or fitted diaper. Boosters are extra absorbent layers stacked on top of inserts for heavy-wetting situations. Understanding the difference lets you customize capacity per use.
Rayon Snap-in Inserts
The Rayon Snap-in Inserts are the standard daytime inserts. Rayon from bamboo is soft, absorbent, and runs cooler than microfiber — which matters on warm days and for babies with sensitive skin. Sold in 3-packs. These are the same inserts included in the starter kit.
EcoAble Hemp/Cotton Booster Inserts
The Hemp/Cotton Booster Inserts are 4-layer inserts made of 55% hemp and 45% cotton — higher absorbency per thickness than any other fabric EcoAble sells. Used as a booster (stacked under a regular insert) for overnight use or heavy-wetting days. Also used on their own as the primary insert if bulk is an issue.
Disana Diaper Booster Pads
The Disana Booster Pads are 100% organic brushed cotton. Simple, unbleached, and pair naturally with Disana fitted diapers. A good option if you're building a full-natural-fiber stash.
For heavy-wetting days or overnight, put the booster (hemp/cotton) under the regular insert. This way the booster catches what the top insert doesn't, and the top insert stays in contact with skin to keep it feeling dry. Flipping the order is a common mistake.
Swim & potty training
3-in-1 Hybrid Cloth Diaper
The 3-in-1 Hybrid handles three different use cases in one garment, for kids ages 1–10:
- Potty training pants. Athletic mesh lining gives a "wet" sensation during accidents that helps build potty awareness. Unlike regular cloth diapers that wick moisture away, this one lets the wearer feel the accident — which is the point.
- Backup cloth diaper during the accident-prone early potty-training weeks. Pulls on and off like underwear.
- Swim diaper with the insert removed. Same garment, dual-use, so you don't need a separate swim diaper purchase.
Not a primary everyday diaper — the mesh lining isn't as comfortable for all-day wear as the rayon-lined starter kit covers. Buy it when potty training starts, or if you need a swim diaper.
How many diapers you need
Most families underbuy when they first start. Running short means you can't keep up with laundry, which leads to panic-buying disposables or washing too often (which wears diapers out faster). A reasonable stash lasts 2–3 days between wash days.
The basic formula
Count how many diaper changes your baby needs per day. Multiply by 3 (for 2–3 days of wear plus buffer). That's your minimum stash size.
| Age | Changes per day | Minimum stash | Comfortable stash |
|---|---|---|---|
| Newborn (0–3 mo) | 10–12 | 24–30 diapers | 30–36 diapers |
| Infant (3–12 mo) | 6–8 | 18–24 diapers | 24–28 diapers |
| Toddler (1–3 yr) | 4–6 | 12–18 diapers | 18–22 diapers |
| Potty training | Varies, often 4–6 | 12–18 including 3-in-1 Hybrids | 18–22 with extras |
Plus overnight and accessories
Nighttime runs separately. Count 3–4 overnight sets (fitted + cover) so you have one for tonight, one for last night in the wash, and 1–2 as backup.
Inserts don't need to match the number of covers one-to-one. Since covers get reused 2–3 times, you typically need about 2× as many inserts as covers.
Start with the starter kit plus an overnight set — enough for 1–2 days of testing. If the system works, order the rest in a second purchase. This approach catches fit or detergent issues before you've invested in the full stash.
Wet bags and accessories
Wet bags are waterproof zipped pouches for storing used cloth diapers until you get home to the wash pile. Every cloth diapering family needs at least one — ideally one small for the diaper bag and one large for the car or at home.
Small Wet/Dry Bag (12×14 inches)
The Small Wet/Dry Bag holds 2–4 used diapers. Fits in a standard diaper bag. Uses:
- Daily outings — park, grocery store, appointments
- Storing damp swimsuits after the pool
- Packing dirty items in carry-on luggage
Large Wet/Dry Bag (16×27 inches)
The Large Wet/Dry Bag holds a full day's worth of diapers (8–12). Uses:
- Pail liner — put it inside your diaper pail, fill it up, then pull the whole thing out on laundry day
- Travel — keep clean and dirty diapers in one bag during trips
- Daycare — send a day's worth of diapers to daycare and bring the used ones home
- Beach and pool days — clean swimsuits and dry clothes in one compartment, wet in the other
The zipped separation lets you put clean items in one side and dirty items in the other. For daycare, that means fresh diapers in the dry compartment, used diapers in the wet compartment — no mixing, no cross-contamination.
Getting the fit right
EcoAble baby cloth diapers are one-size adjustable — snap settings let a single diaper fit a range from roughly 10 lbs to 35 lbs. The adjustability is what lets you use the same stash from infant through toddler, but you need to set the snaps correctly for each stage.
Snap settings by weight
- 10–15 lbs (small newborn through ~3 months): Rise snaps at the shortest setting (usually the top row of snaps, snapped to the bottom). Waist snug but not tight.
- 15–25 lbs (3–18 months): Medium rise setting. Waist can be set wider as the baby grows.
- 25–35 lbs (toddler): Rise snaps unsnapped (or at the longest setting). Waist at the widest usable position.
Signs of good fit
- Legs: Elastic sits in the leg crease, no visible gap, no red marks
- Waist: One finger fits comfortably between the waistband and the belly
- Rise: The top of the diaper sits around or just below the belly button
- No absorbent material visible sticking out of the cover — it should all be inside
Common fit problems
- Gaps at the legs (leaks around the thighs): Too loose, or wrong rise setting — tighten snaps or adjust rise shorter.
- Red marks after use: Too tight — loosen snaps.
- Leaks despite good-looking fit: Usually absorbency, not fit. See why cloth diapers leak.
Babies under 10 lbs — including many 0–6 week-olds — may be too small for one-size diapers even on the shortest setting. For tiny newborns, prefolds folded into a newborn-size cover often work better until the baby grows into the one-size range. Most families switch to one-size diapers around 10–12 lbs.
Care and washing
A proper wash routine is what separates families who love cloth diapers from families who struggle with them. The four care guides below cover everything you need:
- How to prep new cloth diapers — new natural-fiber diapers need 3–5 wash-and-dry cycles before they reach full absorbency. Skip this and you'll get leaks from day one.
- How to wash cloth diapers — the 4-step wash routine for HE and standard machines.
- Cloth diaper safe detergents — tested list of detergents that clean thoroughly without buildup.
- Wool diaper cover care — if you're using Disana or Reiff wool covers, their care is different from PUL.
