How it works

Below are descriptions of the different styles of nappies and photos showing how you use each one. If you would like a comparison of every nappy model, please view our nappy comparison which summarises the features of each product.


All-In-Ones (AIOs)

AIOs are the closest to a disposable nappy in form because the absorbent inserts are sewn in, so the nappy is made up of only one piece. This makes it a lot easier when washing and preparing the nappy because you won’t lose the single parts when washing and putting the nappies back together again.

AIOs are generally the easiest system for other carers to use who are unfamiliar with cloth (grandparents, daycare, babysitters etc.). They also tend to be rather slim and well-fitting nappies, perfect for during the day. AIOs tend to the most expensive nappies and may take a longer time to dry depending on the design.

For full-time use we recommend 20 nappies or when used in combination with night nappies (TotsBots Bamboozle + PUL cover), we recommend 16 AIOs, 3-5 night nappies plus 1-2 PUL covers.

BumGenius Organic AIO Biobaumwolle

1. The inside of the BumGenius Organic nappy has two absorbent panels that are attached to the nappy at both ends.
2. Place a nappy liner on top of the nappy.

3 & 4. Close the nappy using the snap buttons to ensure a good fit.

TotsBots Easyfit AIO Minky

1. The TotsBots Easyfit has a long double-sided sewn-in minky insert. At the back there is a pocket covered by a flap.
2. Fold the absorbent panel so that more absorbency will be where it is needed. More at the front for boys or more in the middle for girls.

3. Fold the insert into the pocket and flatten out. An extra insert can be added here if necessary. Close the flap over the pocket.
4. Lay the stay dry fleece and/or nappy liner on top of the nappy.

5. Close the nappy using the snap buttons or velcro and ensure a good fit.

Hybrid AIOs

Hybrids are a type of AIO where the inserts can be removed and reattached through a snap button. If the absorbent insert is wet, you can replace it with a fresh insert and reuse the cover. If the cover is dirty or also saturated, then you would put both the cover and inserts in the washing. By having extra inserts and reusing the cover, this means less washing and less costs overall.

Another advantage is that you can use disposable inserts for times when you might resort to disposable diapers such as during long-distance travel, camping or when the child has diarhoea. The disposable inserts are placed inside the cover instead of cloth inserts and are then thrown away after use. A major advantage of disposable inserts over disposable diapers are that they are usually 100% biodegradable, unlike one-use diapers which take hundreds of years to biodegrade.

For full-time use we recommend 10-15 complete Pop-Ins plus 10 extra absorbent inserts (soakers and boosters). Night boosters are included in the boxes of 5 and 10 nappies. If using Pop-Ins in combination with TotsBots Bamboozles with a PUL cover for nights, we recommend 10 complete nappies, 10 extra inserts, 3-5 Bamboozles and 1-2 PUL cover of each size.

Pop-In AIO Bambus/Minkee

1. A Pop-In cover (centre) with two bamboo inserts.
2. The absorbent insert can be attached to the nappy cover by popping-in the four snap buttons (two at the top, two at the bottom).

3. The top booster insert can be folded to increase absorbency where needed. More at the front for boys or more in the middle for girls.
4. Place the nappy liner on top of the nappy.

5. Close the nappy and ensure a good fit using the velcro tabs.
6. The wet insert (yellow) can be unbuttoned and replaced with a fresh insert (grey) in the same cover.


At the back or sometimes front of the nappy, there is an opening large enough to stick your hand into - the “pocket” - and this is where the absorbent inserts or boosters are stuffed into. An advantage of this system is that you can add enough absorbency as required by your baby. A single insert will usually suffice for a smaller baby, while two inserts will be needed for an active toddler or for the heavy wetter. At night a third insert such as a night booster or hemp insert can be added for extra security.

Usually the inserts need to be removed again from the pocket before being washed. The best time to do this is just after changing your baby and before putting them into your nappy pail or washing bag. You can just pull out Of course you’ll also need to stuff the inserts back into the pockets before using them again. Some mums do this while sorting through the dried laundry, so that they have a stack of nappies ready to go at changing time.

Fitted nappies and covers

Fitted nappies look similar to pockets or AIOs, however they don’t have an integrated waterproof layer. Instead the entire nappy is made out of absorbent material (rather than only the inserts) and it needs to be worn with a waterproof cover. The advantages are that together with a cover they become an almost leakproof system lasting up to 10-12 hours and are therefore awesome night nappies!

They also contain a high percentage of natural fibres (bamboo, cotton or hemp), so they are great for those who wish to avoid synthetic fibres in direct contact with their babies’ bottoms.

Of course they are not only super night nappies and can be worn during the day as well, but as they are often much thicker than pockets or AIOs. This means that they don’t always fit under regular trousers or stockings and you may need pants that are a size bigger for your little one to wear.

Fitted nappies in general take longer time to dry as they often contain several layers of absorbent natural fibres sewn together that cannot be separated.

TotsBots Bamboozle Fitted Nappy & TotsBots PUL Flexiwrap

1. Open up the PUL cover and lay flat. Open up the Bamboozle fitted nappy and lay flat on top of the cover. The sewn-in insert can be folded to adjust absorbency.
2. Lay the stay dry fleece and/or nappy liner on top of the nappy.

3. Close the nappy using the velcro closures.
4. Finally close the cover over the nappy using the velcro closures.
