To put on a cloth diaper, you fold or place the absorbent layer under your baby, bring it up between the legs, fasten it snugly at the sides, and then add a waterproof cover if your system uses one. Done correctly, the diaper holds fluids in, sits close to the body without pinching, and stays put through a full wet cycle. The exact steps depend on the type you own, so this guide covers the main styles and the fit checks that apply to all of them.

Before You Start: Gather Your Supplies

Having everything within reach makes diaper changes faster and reduces the chance of a mess on the change table. Keep these items ready:

Shopping for one? See our guide: Cloth Diapers or Disposable (2026): Which Is Better for Your Baby?.

  • A clean, dry diaper of your chosen type
  • Diaper cover, if your system uses a separate waterproof layer
  • Flushable liners or a diaper sprayer for solids, if you use them
  • Cloth wipes or disposable wipes and a lidded pail or wet bag for soiled items
  • Diaper cream, applied only where needed and only if your pediatrician recommends one

Step-by-Step: Putting On a Prefold or Flat Diaper

Prefolds and flats are the most versatile option, and they take a little practice. Most parents find the process comes quickly after a few changes.

  1. Lay the cover flat with the waistband toward the back, then lay the prefold inside it. Center the thickest part of the prefold where the baby’s bottom will sit.
  2. Lift your baby’s legs gently, slide the diaper under the bottom, and bring the front up over the belly.
  3. Fold the front panel down slightly so it sits below the navel, which helps prevent leaks at the waist.
  4. Pull the legs of the cover outward and check that the prefold is tucked inside, not bunched up.
  5. Fasten the cover snaps or hook-and-loop tabs at the front, keeping them snug but not tight.

Fold Options for Prefolds

A tri-fold works well for newborns, since the extra layers in the center absorb a lot of urine. As your baby grows, a “bi-fold” or a simple rectangle laid in the cover gives more coverage at the back. Try one fold for a week, and switch if you see leaks at the legs or the back.

Step-by-Step: Putting On an All-in-One or Pocket Diaper

All-in-one (AIO) and pocket diapers are the simplest to use, and they’re a good choice if you have a caregiver who needs an easy routine.

  1. Open the diaper fully and check that any inserts are in place. For pockets, stuff the insert into the pocket opening and make sure it lies flat.
  2. Place the diaper under your baby, with the back higher than the front.
  3. Bring the front up, then fasten the tabs or snaps at the sides. Adjust the rise to fit your baby’s size, using the lowest setting for a newborn.
  4. Run a finger between the elastic and your baby’s thigh. You should be able to fit one finger snugly, not two.

Checking the Fit to Prevent Leaks

Most leaks come from fit problems, not from the diaper itself. Check these three areas after every change:

Area What to check Fix if wrong
Waist Front sits at or just below the navel Lower the front panel or adjust the rise
Legs Elastic is snug, with one finger fitting between leg and elastic Loosen the snaps one setting, or tighten if gaps show
Back Cover reaches the lower back without wrinkling Move the rear insert or try a different fold

Common Mistakes to Avoid

  • Fastening the cover too tightly, which can leave red marks and restrict movement.
  • Forgetting to tuck the prefold inside the cover, which causes leaks at the legs.
  • Placing the absorbent layer too far back, which leaves the front dry and the back soaked.
  • Using a diaper size that’s too big for a newborn, since gaps at the legs let urine escape.
  • Skipping a check after every change, so a loose tab or bunched insert goes unnoticed for hours.

A few supplies make daily use easier. Look for these product types:

  • Prefold diapers are affordable, absorbent, and flexible to fold, which makes them a practical staple for both newborns and older babies. View on Amazon
  • Waterproof diaper covers with snaps or hook-and-loop closures keep prefolds and inserts in place without leaking through clothing. View on Amazon
  • Wet bags give you a sealed place to store soiled diapers between changes and washes. View on Amazon

FAQ

Do I need to use a cover with every cloth diaper?

Prefolds and flats need a waterproof cover, but all-in-one and all-in-two diapers already have a waterproof outer layer. Pocket diapers are also self-contained once the insert is in place.

How tight should the elastic be?

The elastic should be snug enough that you can fit one finger between the leg and the elastic. If you can fit two fingers, tighten it one setting. If the leg marks stay red after the diaper is removed, loosen it.

How often should I change a cloth diaper?

Check and change the diaper whenever it’s wet or soiled, and at least every two to three hours during the day. Newborns usually need more frequent changes. If you notice persistent rash or other skin concerns, talk with your pediatrician.

Conclusion

Putting on a cloth diaper takes a few practice rounds, but the steps are consistent across types: layer the absorbent part correctly, fasten snugly, and check the fit at the waist, legs, and back. Once you have the routine, changes become quick and leak-free. For washing and care, see How to Wash Cloth Diapers.
