Thoughtfully designed for comfort, fit, and performance
Lilly & Frank fitted diapers are designed to hold everything in while staying soft and comfortable against your baby’s skin. Every detail is intentional — from the fit, to the materials, to how they perform in real life.
Absorbent everywhere
Unlike many diaper styles, fitted diapers provide full absorbency from waist to leg, helping prevent leaks and blowouts.
Soft, flexible fit
Gentle elastics and thoughtful shaping allow for movement without gaps, digging, or compression leaks.
Built for heavy wetters & overnights
Ideal for naps, nighttime, and babies who out-pee other diaper styles.
Handcrafted with premium materials
Each Lilly & Frank fitted diaper is sewn in small batches using high-quality, natural fibers and thoughtfully selected designer knits. These materials are chosen for softness, durability, and beauty — creating diapers that feel as good as they perform.

Built-in absorbency where it matters.
Our fitted diapers include an 8-layer snap-in insert paired with a double-layer booster for customizable absorbency. This setup provides reliable protection for daytime use, naps, and overnights — without folding, stuffing or guesswork.
One diaper, adjustable fit.
A simple fold-over rise allows you to adjust the diaper as your baby grows. Just fold and snap to customize the fit — no additional sizing pieces or inserts required.
Adjust the rise snaps for your baby’s size.
Place the fitted diaper on your baby and fasten.
Do I need a cover?
Fitted diapers are highly absorbent on their own. Many families choose to use them without a cover at home or outside during warmer months, changing once the diaper feels damp.
Covers are typically used for:
- Naps and bedtime
- Travel or outings
- Families who prefer a fully waterproof system throughout the day

Fitted Diaper FAQs
What is a fitted diaper?
A fitted diaper is a fully absorbent cloth diaper that fastens like a disposable but is made entirely of soft, breathable fabric. Because it’s absorbent from waist to leg, it offers unmatched leak protection — especially for heavy wetters, naps, and overnight use.
Are fitted diapers worth it?
Fitted diapers are often chosen by families who:
- Need reliable leak protection
- Have heavy wetters
- Want a natural-fibre option
- Value comfort, craftsmanship, and longevity
They’re not the simplest diaper — but for many families, they’re the most dependable.
How many fitted diapers do I need?
This depends on how often you plan to wash and whether you’ll use fitted diapers full-time or primarily for sleep and heavy wetting.
Many families start with:
- 3–6 fitted diapers for part-time cloth, naps and overnight
- 14–21 fitted diapers for fuller daytime use
You can always build your stash over time.
Why are fitted diapers more expensive?
Each Lilly & Frank fitted diaper is hand-sewn in small batches using high-quality, natural fibres. We also use carefully selected designer knits — often sourced from specialty European fabric shops — chosen for both beauty and durability.
These diapers are made to perform, last, and feel good against your baby’s skin — not to be disposable or mass-produced.
This is quiet luxury, built for daily use.
How absorbent are they?
Toddler, One Size, and Petite fitted diapers come with:
- An 8-layer snap-in insert
- A double-layer booster
This combination provides customizable absorbency suitable for heavy wetters and overnight use.
Are newborn fitted diapers available?
Yes. Newborn fitted diapers are available for families who plan to cloth diaper from birth and want a truly newborn-sized fit without folding or adjusting a one-size diaper in the early weeks.
How do I adjust the size as my baby grows?
Lilly & Frank fitted diapers use a fold-over rise system that allows you to customize the fit through multiple stages. This helps reduce bulk while maintaining absorbency where it’s needed most.
Is a fitted diaper hard to use?
Not at all. If you can put on a disposable diaper, you can use a fitted diaper.
The main difference is that fitted diapers are absorbent on their own and may be paired with a cover when waterproofing is needed.
Do I need a cover?
Sometimes — not always.
Many families use fitted diapers without a cover at home, especially during the day or in warmer months, changing once the diaper feels damp.
Covers are typically used for:
- Naps and bedtime
- Outings or travel
- Families who prefer a fully waterproof system all day
Is a fitted diaper right for you?
Ideal choice if you:
- Want a natural-fiber, high-absorbency option
- Need reliable protection for overnights or heavy wetters
- Value small-batch, thoughtfully made quality
You may prefer our All-in-Two system if you:
- Are brand new to cloth diapering
