Looking for V3 Nappy Bundles?

Just add your favourite nappies to cart and the following discounts will be automatically applied:

6% off 6 nappies or more
12% off 12 nappies or more
24% off 24 nappies or more



Each material has been maliciously chosen to serve a specific purpose, some materials are designed to act quickly, and others are in it for the long haul.  This is just one of the many benefits of Bubakin Modern Cloth Nappies, we know not all children have the same toilet habits and inferior absorbency is one of the main causes of leaky nappies (especially overnight).

What’s more, you can adjust the position of your Inserts and Boosters inside the nappy to account for your child’s specific needs, whether they are boy vs girl, tummy sleepers or heavy wetters.

CORE Insert

  • Our V3 inserts have been designed to bring you the best of both worlds, the V3 CORE Insert consists of 5 layers in total, the 2 outer layers consist of 80/20 Bamboo Terry and draw moisture away quickly into the 3 core inner layers which consist of 70/30 Bamboo Cotton Fleece.
  • The CORE Insert is designed to be stuffed inside the shell pocket as the absorbent layer, or you can snap into place and lay the insert on top of the lining (close to baby’s bottom) with the front flap folded neatly over the top.

Mini Booster/Liner

Consisting of 4 thirsty layers of 70/30 Bamboo Cotton Fleece (the same material on the inner layers of the CORE insert) this insert might be little but it super thirsty and can be used in the following ways:

  • Pop the mini booster/liner on top of the lining of your nappy shell (against baby’s bottom) and tuck under the front flap to hold in place, you can then easily remove the number twos and simply plop them into the toilet.
  • If you are experiencing some leakages, pop this little wonder insert UNDERNEATH you CORE insert inside the pocket, this will boost your absorbency and provide extra protection for heavy wetters/toddlers/tummy sleepers

    I love these inserts. I’ve replaced some of my other inserts with these because they are so thirsty. We can get 4 hours on the bum with no leaks! Impressive design and I love that the insert snaps in to the pocket to keep it still with my crocodile rolling child.
