Reusable nappies: everything you need to know

DEFRA recently released their 2023 report on 'The life cycle analysis of nappies'.

The report shows that reusable nappies are proven to be better than disposable even after washing and drying is taken into consideration.


The report also showed reusable nappies produce 25% less co2 emissions than single-use disposable nappies and that the environmental impact of production is 90% less in reusable nappies than single-use disposable nappies!

So more than ever, there really has never been a better time to make the switch.

Change can feel overwhelming, so where do you start?

TMM in partnership with Modern Cloth Nappy has got you covered...


Some parents make the switch straight away, others go part time. Either way - any change is a positive step. We’ve got you covered for both.

Using reusable nappies part-time: Based on using 2-3 reusable nappies per day on a part-time basis we recommend you have 8-10 nappies with washing every 1-2 days.

Using reusable nappies full-time: For full-time use we would recommend 18-25 nappies. This is based on using 6-8 reusable nappies per day and to allow 1-2 days between washing.

Changing Times for Cloth Nappies:

When it comes to changing nappies, we recommend you change your baby’s nappy around every 2-3 hours, earlier if soiled. You can boost your baby’s nappy for night-time use. This is a guide; you may find you achieve longer or shorter times in modern cloth nappies depending on your babies age and how much they wee/poop.


Cloth nappies don’t sit as high up babies' backs as disposables do. For cloth nappies, it should sit just above the hips and leave enough room to fit three fingers at the front. 

This leaves a little space for sitting up and movement.

It may take a few times to get used to which fit suits your baby best to avoid any leaks or them being uncomfortable. 

Cloth nappies grow with you. As your baby grows, you can simply adjust the fit.

The style of nappy you use determines whether you’ll need to add in any extra absorbency. 

The absorbency required depends on whether your baby is a heavy wetter or not, and if you are using your nappies overnight.

This can be a case of test and learn to discover what suits your baby best.


Simply flush any solids down the toilet or dispose of the biodegradable liner in the bin (if used), then store your nappy in a bucket or wet bag until wash day. 

We have several storage options - we’ve linked some here. 

We recommend that you do not leave nappies anymore than 2-3 days between washing.

The MCN recommended wash routine suggests:

  • PRE-RINSE (40 mins approx on a rinse & spin cycle)
  • LONG WASH PROGRAMME (2.5 hours minimum at max 60°c)
  • HANG DRY (or tumble dry on low if essential)

 We recommend regular washing at 40°c to prolong nappy life.

The best way to dry our reusable nappies and inserts is by hanging on a line or you can tumble dry on low if essential.

Switching to reusable, sustainable products are not only kinder to the skin, but helps leave little carbon footprints for our little people.

We know the change can be a scary one and you may have questions.
