Nappy basics
Parts of a reusable nappy
Fleece liner
A fleece top layer next to your baby’s bum is what will keep them dry and comfortable. Modern microfleece works by wicking away wee from the surface so it can be absorbed by the nappy or booster. The pile of the fleece also helps hold poo stay put.
A big help!
Fleece liners will take the brunt of most poo explosions which is why they are so important, even in a pocket nappy which has it’s own top layer of microfleece they can help to prevent stains.
I believe they should be included!
Fleece liners protect both your baby and your nappy investment which is why I supply a free homemade one if not already provided by the manufacturer. It’s also helpful to use an additional biodegradable liner on top when away from home.
Nappy / Insert
The second or middle layer is the absorbency, which can take a variety of forms depending on nappy type. In an all-in-1 nappy or 2-part nappy absorbent pads will already be sewn in, in a pocket nappy it will be removable in the form of a “booster“, in a terry square or flat it will be formed as layers in the folding.
How do they work?
Different fabrics hold more or less than others, but also dry slower or faster. The most common are as follows:
Cotton - dries fast but doesn’t hold as much liquid as bamboo or hemp
Bamboo - holds more fluid than cotton but takes longer to dry
Hemp - holds the most so ideal for nights, but takes the longest to dry
Outer layer
The PUL (Polyurethane Laminate) outer layer is what keeps the liquid (or solids) inside the nappy and your baby’s clothes dry.
Is it comfortable?
Modern PUL is breathable and so it’s not classed as completely waterproof, however it creates the best conditions for both air circulation and protection. It’s also soft and comfortable even around the leg elastics, and allows nappy brands to compete with stylish and desirable prints.
Why do types of nappies all look different?
The outer layer can be attached in an all-in-1 nappy or pocket nappy shell, or in the form of a separate wrap or cover over a folded terry or 2-part nappy. It’s also what wet bags are made from.
