All-In-One (AIO): The absorbent part and water-resistant part are all sewn together and do not come apart. The easiest of cloth nappies to use and it’s ready to go when dry; no prepping, folding or stuffing needed.
Aplix: The sticky strip fastening for nappies. Although it gives a snug fit it is not as durable as poppers and can easily be pulled off by toddlers.
Birth to Potty (BTP): These are size adjustable nappies that fit from birth through potty training. These are a popular choice as they are economical as you will not need to purchase new sizes as your child grows. They can be a poor fit on smaller babies.
Bamboo: A natural fibre that has antifungal and antibacterial properties. It is highly absorbent and super soft. Bamboo is an eco-friendly crop that requires less land, water and no pesticides.
Booster: An absorbent insert that is either laid in, popped on stuffed into the pocket of your nappy.
Cotton: A natural fibre with good absorbency. It wears well due to its robust fibre.
Cover: see “wrap”.
Crossover poppers: Poppers that are placed on the securing tabs of the nappy that pop together for smaller waists. The tabs cross-over when the cross-over poppers are used.
Dry pail: The process of storing used nappies before washing. Modern cloth nappies are not to be soaked in chemicals or any liquids before washing, they are stored in a large wet/dry-bag or bucket.
Fitted: These nappies have no water-resistant layer and are only made of absorbent material so need a cover/wrap to use with them. They are generally made with hemp, bamboo or cotton. These can be slow drying nappies but generally they are really good for night times and heavy wetters.
Flat Nappy: A piece of absorbent fabric that requires folding before use, a cover is needed over the top.
Hemp: Hemp is a natural fibre that is extremely durable and naturally antimicrobial. It is the most environmentally friendly fabric used in cloth nappies as it’s an eco-friendly crop that is fast growing and requires less water, fertilisers and pesticides than cotton crops. It has super absorbency although slow but stable.
Hip popper: Poppers that are placed on the securing tabs near the hips to prevent wing-droop.
Hook and loop: see “aplix”.
Insert: This is the absorbent part of the diaper, usually made from either microfibre, bamboo, hemp, or cotton. Either pad shaped or a folded square.
Liner: An optional extra that is put between baby’s skin and the nappy and catches any solids. These can be disposable or reusable (and washed with the nappies) but is not absorbent. Common types are Fleece reusables or Bamboo disposables. You can also get Stay-Dry liners that wick moisture away from your baby's bum.
Microfibre: A fast absorbing man-made fabric that holds the liquid between the fibres rather than absorbing it into them. It dries very fast although not as absorbent as other fabrics. Microfibre should not be placed directly next to baby’s skin, stay-dry lined, a liner or stuffed into a pocket is fine, otherwise it can cause irritation as it pulls moisture from baby’s skin. Microfibre is prone to compression leaks so pair it with a bamboo or hemp booster to stop compression leaks.
Minky: a velvety, fluffy polyester fabric commonly used as an outer in modern cloth nappies or as an absorbent core. It’s extremely soft but it does not hold a lot of liquid.
Nappy bucket: Traditionally nappies were soaked in a chemical solution in a nappy bucket. Modern cloth nappies do not need to be soaked; wet\dry bags are an alternative. Nappy bucket can also be known as a nappy pail.
One-Size (OS): see “birth to potty”.
OSFM: An abbreviation of One Size Fits Most (see "birth-to-potty")
Pocket Nappy: A two-piece system; the water-resistant pocket and an insert you stuff into the pocket for absorbency. Pockets can be stuffed with different inserts (Bamboo, Hemp, Microfibre etc) to suit your baby's needs. The pockets need to be stuffed before use and inserts removed for washing.
Popper and Pocket: A two-piece system (water resistant cover and absorbent insert) that can be used in two different ways. It can either be used as a Pocket Nappy by stuffing the outer water-resistant shell with an insert of your choice or the insert can be laid in and popped/snapped on.
Poppers: Plastic press studs that fasten and adjust the nappy, known for their durability and resistance to nappy curious toddlers. Also known as snaps.
Prefold: see “flat nappy”.
Rise: The rise of a nappy refers to the measurement from the waist at the front, to the waist at the back of the nappy. Different sized nappies have different rise measurements. You can adjust them with poppers, to make smaller or undo them to make larger as your baby grows.
Shell: see “wrap”.
