Cloth nappy questions

How will using cloth nappies save me money?

Using cloth nappies saves approximately $2,000–$3,000 from birth to toilet training compared with buying disposables. The savings multiply if you use the same nappies for your next baby, and you save more again with cloth wipes.

How many nappies should I buy for full-time use?

We recommend 24–36 nappies for full-time daytime use, depending on how often you wash and how long they take to dry. For the best rotation and drying times over the long term, 36–40 nappies is ideal.

I'm not sure if I want to do cloth yet. Where should I start?

Starting cloth doesn't have to be all or nothing. Lots of families use cloth part-time. You'll need about 6–9 nappies for a full day. Our 3 Nappy Trial Packs are an easy way to try before you commit.

How do I wash my cloth nappies?

To keep your Designer Bums nappies in the best condition, read the care and washing instructions before first use. You'll find everything in our Care Instructions.

Can I use Designer Bums nappies at night?

Our All-In-Two nappy isn't a dedicated night nappy, but many customers use them overnight with extra boosting. Our Large Nappies with extra inserts work well for nights.

How long will my nappies last?

Like any clothing, cloth nappies don't last forever, but with the right care Designer Bums nappies are built to last through your growing family. Many are passed down to the next baby or resold pre-loved.
