All-in-Two vs. Fitted Diapers: Which Cloth Diapering System is Right for Your Baby?
If you're building your cloth diaper stash, you've likely come across two popular options: All-in-Two diapers and Fitted Diapers. Both are reliable, reusable systems - but they work differently and suit different families.
Let's break down how each system works, the benefits of each, and how you decide which is best for your baby and your routine.
What is an All-in-Two (AI2) Diaper?
An AI2 diaper, like the Mother-ease Wizard Duo, is a two-piece diapering system made up of:
- A waterproof outer cover
- A snap-in absorbent insert
The insert snaps securely into the cover and absorbs urine, while the waterproof cover prevents leaks.
How it works
When your baby wets the diaper:
- Remove the soiled insert
- Snap in a clean insert
- Reuse the same cover (as long as no poop got on there!)
This means fewer covers are needed in your stash.
Benefits of AI2 Diapers
- Cost-effective stash building - Fewer covers required
- Customizable absorbency - Daytime and nighttime insert options
- Quick diaper changes - Goes on baby in one-step
- Trim fit under clothing
AI2 sytems are often chosen by families who want convenience wihtout committing to a fully sewn All-in-One diaper.
What Is a Fitted Diaper?
A Fitted diaper, like Mother-ease Sandy's Fitted or One Size Fitted, is a fully absorbent cloth diaper shaped to fit your baby's body. It includes elastic at the waist and legs for a snug, leak-free fit.
Unlike an AI2, a fitted diaper snaps around your baby on it's own, and then the waterproof cover is snapped around the diaper in a second step.
How It Works
- Put the absorbent fitted diaper on baby
- Add a waterproof cover over top
- When soiled, remove both the cover and the diaper, snap a clean diaper around baby, and reuse the cover over top of the clean diaper (as long as no poop got on there!)
Because the absorbent diaper is completely full coverage all around baby, fitted diapers are known for excellent leak protection and containment.
Benefits of Fitted Diapers
- Exceptional absorbency
- Excellent containment for heavy wetters
- Great for nighttime diapering
- Soft, full coverage around baby
- Reliable fit for newborns and breastfed babies
Many parents appreciate the security and simplicity of a fitted + cover system, especially during the newborn stage or overnight.
AI2 vs. Fitted: Side by Side Comparison
| Feature | AI2 | Fitted Diaper |
|---|---|---|
| 1 or 2 step | One-step on baby | Two-steps on baby |

Which Should You Choose?
Choose an AI2 if you:
- Are looking for a trimmer fit
- Want economical convenience
- Want to send your diapers to daycare
- Are looking for a modern fit
Choose a Fitted diaper if you:
- Need maximum absorbency
- Have a heavy wetter
- Want dependable night time protection
- Are looking for a workhorse diaper, and don't mind a fluffy cloth bum
Many Families Use Both
Cloth diapering doesn't have to be one-size-fits-all. Some parents use AI2s during the day, and fitteds at night. Others prefer fitteds for newborns and switch to AI2s as baby grows.
Building a stash that works for your baby's wetting needs and your convenience level is the real goal.
Both AI2 and Fitted diaper systems offer dependable, reusable diapering with long-term savings and environmental benefits.
The best system is one that fits your baby comfortably and matches your lifestyle.
And no matter which system you choose, you can feel confident knowing that all Mother-ease diapers are thoughtfully designed to be leak-free, durable, and exceptionally comfortable for your baby. From carefully engineered elastics to high-quality fabrics and absorbency options, every diaper is made to provide reliable performance wash after wash.
