Frequently asked
?
Are reusable nappies really better for the environment?
Yes, beyond the break-even of about 7 weeks of use, assuming a typical UK electricity mix. The manufacturing impact is paid back relatively quickly. Washing at 60°C vs 40°C significantly affects environmental balance — wash at 40°C with a full load.
?
What's the best way to start with reusable nappies?
Start with a trial kit (5-10 nappies from a nappy library or rental scheme) before committing. Most local councils have free nappy advice services. Birth-to-potty one-size nappies are the most economical — they adjust from newborn to 35 lbs.
