Southwark Council is giving away trial packs of cloth nappies to encourage parents in the borough to ditch the disposables and move over to the real thing.
Chaucer ward's Cllr Richard Thomas, Southwark Council's executive member for environment and transport (pictured with his daughter Megan who wears cloth nappies), said: "Using cloth nappies can cut a household's rubbish in half and will help us reduce the number of disposables that are sent to landfill.
"Real nappies are a cheaper alternative to disposables and are easier to use than you think. Anyone deciding to switch to cloth nappies will be surprised at how far the modern versions have moved on."
Cllr Thomas is not contesting Chaucer ward in this year's council elections, instead standing as a Lib Dem candidate in a ward in the south of the borough.
