General aspects

Inserts ensure the absorption of moisture and are placed in the middle of the wool cover or are folded around the child. How much your baby pees and how often you change the nappy determines the type and amount of inserts.

Inserts are typically made of cotton, viscose, bamboo, and hemp, or a mixture of the materials. Each material has its own characteristic of how effectively moisture is absorbed. Inserts made of pure cotton absorb moisture quickly, so they are convenient to lie on top. Materials such as bamboo and hemp are highly absorbent and are often used as “booster” underneath.

Folding insert

A folding insert is a larger piece of fabric that can either be folder around the child or directly put in the nappy.

Because of the variable use folding inserts will accompany you throughout the entire time of changing nappies, from the first day until the last. The inserts are often made of 100% organic cotton (terrycloth or muslin) or hemp/cotton.


A liner is a thin single layer of fabric, which is placed on top insight the nappy. One distinguishes mainly between two fabric types: Cotton and wool.

Liners made of 100% organic cotton are ideal as top layer. They absorb the moisture quickly and pass it on downwards, but still allow moisture feedback. Liners made of 100% wool are often used for children who are sensitive to moisture.


A booster is a highly absorbing insert that is made of several layers of fabric, often from hemp and/or bamboo. It can be used in many ways.

Insight a prefold/muslin nappy or directly in the cover. They are best placed underneath a fast absorbing insert of e.g., cotton. Long boosters absorb on the total length whereas short boosters provide some extra absorption where needed: For boys rather at the front and for girls in the middle of the nappy.

“What do I need ? – That is probably the most confusing question at the beginning”


A newborn doesn’t pee a lot, hence inserts of cotton are sufficient. With time more absorption will be needed, which is then provided through boosters or multiple layers of different fabrics. There is no straight forward answer to the question “What do I need”, because every child is different and every parent prefers a different system. However, some general things apply:

  • The classical muslin nappy is folded around the child and  hold together with a nappy clip. This is probably the cheapest option to start with wool nappies. 
  • Liners made of terrycloth (100% organic cotton) reliably catches the still liquid faeces of newborns, hence, the wool cover gets dirty less often
  • Folding inserts made of terrycloth (100% organic cotton) can be folded around the child like a nappy or along the narrow side for newborn covers. Once the child grows up the insert can still be used for short changing intervals or above highly absorbent inserts, such as hemp and/or bamboo boosters. 
  • Prefolds are cloths of cotton fabric that are multilayered in the middle (where most absorption is needed) and single layered at the sites. They are either folded around the child like a nappy or folded and used as a classical insert 
  • Especially at the beginning you can also use all types of fabrics, even washcloths and towels 
  • An additional booster made from hemp or bamboo provides some extra absorption and can be combined with all systems mentioned above

Infants and toddler

When the child grows up you will probably need other combinations of inserts and boosters compared to a newborn. From my perspective, one thing is important: Just try out different combinations and you will find the one that works best for you, and your child.

  • A fast absorbing layer of pure cotton is often placed on top. It absorbs the moisture quickly and passes it on downwards, but still allows moisture feedback.
  • Beneath comes an absorbing layer of hemp and/or bamboo, or multiple layers of cotton: Either as booster or folding insert
  • In addition, you can use all inserts from the list of the “newborn”, simply folded and placed directly insight the wool cover

Great, but what about poep?

No worries! That is easy. One can distinguish between relatively fluid faeces from a newborn and solid poep. The insert can be added directly to the laundry, and faeces from breastfeeding and melk formula are easily washed out. Once the poep becomes more solid there are two possibilities: Either you give the poep directly into the trash/toilet, or you use a thin nappy liner made of cellulose or viscose. The nappy liner goes into the trash together with the poep. Please do not use the toilet as it only decomposes slowly. To reduce trash most nappy liners can also be washed a couple of times together with the inserts if only urine was in the nappy.

Washing as a routine and how to save water

To save water, you can pre-wash the inserts in the washing machine so that they no longer smell. Then you add another laundry (bed linen, towels, washcloths, etc.) and wash everything together. Keep in mind that inserts made from hemp or bamboo will need some more time to dry compared to inserts of pure cotton quality.
