Fitted diapers that have a waterproof outer layer and the absorbent soaker that is typically sewn in. Fasten with hook/loop or snaps. Most day cares prefer this type of cloth diaper because of how similar they are to disposable diapers (in the sense of putting on and taking off).
Similar to an AIO, but the soaker isn’t attached, so you have two separate pieces which decreases drying time. Usually the separate pieces can be attached with snaps or laid in.
Outer layer is waterproof and inner layer is a stay dry material like micro fleece. Closures are either hook/loop or snaps and have a pocket opening that allows you to stuff an insert, prefold, doubler, micro fleece insert or a terry wash cloth. Can adjust overall absorbency by adding an additional layer into the pocket.
Sized, contoured and fitted to baby’s shape with elasticized waist and leg openings. You would fasten with plastic snaps or Aplix Velcro. Fitted diapers still need to be covered with a waterproof cover, however they skip the folding and securing of a prefold and act as another barrier to hold in messes.
Provide a waterproof outer layer for non-waterproof diapers.
Doublers or Newborn inserts
Pad-like absorbent soaker, often made out of micro fleece, hemp, organic cotton or bamboo, that can be added to a diaper to increase absorbency or you can use these for newborns to achieve a trimmer diaper.
One-layer diapers that are like “old-fashioned” diapers; require folding and pinning.
Hook & Loop
Velcro-like closures typically made from Aplix or Touchtape.
Hybrid Hybrid diapers consist of a washable, reusable cloth diaper cover which can be used with either biodegradable disposable inserts or washable cloth inserts.
Wool soakers with long legs forming pants.
Rectangular shaped diapers that must be folded into the shape of a diaper. They are like flats, but have multiple layers with more layering in the middle. May see descriptions like 4x8x4, which would mean 4 layers in the outer sections and 8 in the inner section. Will need to use a diaper cover over a prefold and most prefer to fasten the prefold with a Snappi.
