Frequently asked
Are reusable nappies really better for the environment?
They can be, mainly because they cut waste, but the benefit depends on how you wash them. Studies have found the difference is smaller than people expect and depends on washing habits and how long the nappies are used. 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.
