AIO - All-In-One - AIOs are fitted diapers that have a waterproof outer layer. This layer usually consists of fabric that has a PUL (PolyUrethane Laminate) backing, polar fleece, or wool. These are the closest in similarity to disposable diapers since they are a one-piece, single-use (before washing) diapering system. The absorbent soaker material is often sewn into the diaper; it may also be detachable to aid in drying time. DAYCARE, GRANDPARENT, DAD APPROVED.

Thirsties All in One

  • Single use, just like a disposable. Once it is dirtied, into the wash it goes.
  • EASY
  • Snaps (in this case) don't wear out and prevent a curious toddler from taking off her diaper!
  • Longer drying time
  • Wear items like elastic, PUL (waterproof material), velcro get washed everytime.
  • Usually the most expensive system.

AI2 - All-In-Two - AI2s are very similar to AIOs with the exception that the absorbent soaker material is not attached to the diaper in any way. The soaker is usually a second, separate piece that must be used in conjunction with the diaper. This will definitely aid in drying time. Once snapped together, acts like a one-piece diaper, easy-on, easy-off.

  • Reusable shell - if baby is wet, simply snap out soiled liner and snap in new. This way, you can get away with only buying 12 covers/shells if you have 18-24 inserts.
  • No pulling out an insert from a pocket which can get pretty gross!
  • Good for travel - 6 soakers take up less space than 6 AIOs
  • GroVia even has the option of using soft, truly biodegradable soakers which act like a hybrid disposable (perfect for travel, sickness, laundry day!)
  • The thick soakers do take longer to dry than a polyester-based pocket diaper.
  • Other caregivers (Dad, Grandma, etc.) many times don't get the snap-in/snap-out aspect so they just grab an entirely new one to use. (shell not reused)
  • More difficult to add boosters or doublers to customize absorbency.
  • Not recommended for newborns and tiny babies. This system works best with more solid poop.

Covers and Wraps - Covers come in many styles and shapes, but their function is to provide a waterproof outer layer for non-waterproof diapers (prefolds, fitteds). Most fasten with snaps or Velcro. Some covers pull-up, like underpants. Diaper covers are usually made from polyester, PUL, waterproof nylon, fleece or wool.

  • Economical
  • Covers can be reused multiple times before washing if they are not soiled
  • Some come in a One-Size version (like Thirsties Duo Wrap and FLIP)
  • Can put any type of absorbent material inside (prefold, hemp doubler, microfiber doubler
  • Wool covers are breathable and wonderful for sensitive skin babies because they allow breathability
  • Two step system and squirmy baby can get impatient.

Doublers - Doublers are additional inserts (for pocket diapers) or swaths of material that add to the absorbency of a diaper. Hemp absorbs 3x as much as cotton and less bulky. We put a hemp doubler behind a cotton micro-terry insert for naps and nighttime. You can also wrap a prefold around the insert for increased absorbency.

Fitted Diapers - Fitted diapers closely resemble disposable diapers like an All-In-One, however they are not waterproof and require a cover too. They are contoured and fitted with elastic around the legs and back. They fasten with Velcro or snaps and are usually ultra-soft. These diapers are usually sized by weight: Size 1, Size 2, Size 3. They typically do not adjust size from birth to potty like one-size diapers.

  • Trimmer fit
  • Absorbency touching all points of contact with baby
  • Great for infants and small babies when poo is quite runny.
  • Great night diapering solution
  • Also good solution for toddler naps and long car rides due to extra absorbency
  • Ultra soft fabrics touching baby skin - great for sensitive skin babies.
  • Can get expensive having to buy several sets of diapers as the baby grows. These usually

Liners - Liners are thin layers of cloth or paper that are placed inside the diaper to aid in the cleaning of solid waste. Some are flushable. Liners allow the poo to stay on top and the liquids to soak through to the diaper. So when you go to change a diaper, you can lift the solids off with the paper (toss away) and then are left with a less-soiled diaper to clean.

These are recommended once baby is on formula or solids. Not needed with exclusively breastfed babies.

Highly recommended for daycare!! Daycare can simply toss the soiled liners and you don't come home to poopy diapers that have been soiled for hours.

: We had new plumbing in our 130 year old house and a basement - all water/waste is directed to a "poop-grinder-pump" and ejected out a 2" pipe to the sewer line.
I WOULD NOT flush even biodegradable liners in this plumbing system. They don't have time to biodegrade from flush to pump!

Same with an old septic system!

One Size - One Size diapers grow with your baby. Most will fit from birth to potty training (7-35 lbs) - usually by adjusting the rise of the diaper by snapping down the front. Almost all diapers are one-size these days.

  • Grows with baby - only have to buy one set
  • Great when you have 2+ kids in diapers - children can wear the same diaper at different settings.
  • Pretty bulky on a newborn
  • Some complaints that 8-35lbs is stretching the truth a bit. More like 10-30 - but every kid is different!
  • Caretakers can get confused by all the snaps
  • Some don't like the snaps showing on the front once toddler is at the highest settings.

Pocket Diapers - Pocket diapers are like AIO or AI2s. They have an outer layer of a waterproof material and an inner layer of a stay-dry material, like microfleece or suedecloth. They close with velcro or snaps. They have a pocket opening that allows for the absorbent inserts/doublers to be stuffed in the pocket during use and then removed for laundering. Pocket diapers are a popular choice among users because the amount of stuffing can be customized to the baby.

  • Can choose the stuffing absorbency depending on the need (nap, nighttime, outing) or material (hemp, bamboo, microfiber)
  • A must for nighttime (put a hemp doubler behind the microfiber insert for 12+ hour protection!)
  • Most pocket diapers use microfleece against baby's skin, which wicks away moisture from baby.
  • Microfleece and shell dry quickly
  • Once stuffed, these are a one-piece that acts just like putting on/off a disposable, so these are also dad/grandma/daycare approved.
  • Depending on the brand, sometimes you have to flip up an interior pocket to pull out the insert. Mild ick-factor.
  • Adds a second step to laundry b.c. of re-stuffing requirement. (I combat this by NOT re-stuffing and simply stacking the inserts inside a drawer so that I can stuff depending on the time of day).

Prefolds - Prefold diapers are rectangular shaped diapers that must be folded into the shape of a diaper. They have multiple layers with more layering in the middle. The amount of layers varies according to the size you choose, generally ranging from newborn to toddler. You may see a prefold described as being 4x8x4. This describes how many layers there are in the outer and inner sections: 4 layers in both outer sections and 8 layers in the inner or middle section. Prefolds are usually the most economical type of cloth diapers available. They must be used in conjunction with a cover. Prefolds can be attached using a snappi (no more pins!) or it can also simply be folded in a rectangle and laid inside a cover.

  • Will fit every baby
  • Economical
  • Recyclable (my husband covets them for washing his car!)
  • Natural fibers are more easily cleaned
  • Flat piece of cloth is more easily cleaned than a diaper with crevices and seams
  • Durable! These will last for all of your babies (as opposed to the "fancier" pockets, AIO, etc)!
  • Great solution for newborns who go through so many diapers a day!
  • Longer drying time.
  • Learning curve to master folding and 'pinning' technique
  • Bulky on baby
