LONDON families are invited to try a free seven-day pre-Christmas challenge for outgrown children's clothes, toys, books and baby belongings.

Outgrown, Not Wasted tackles one category each day rather than a whole-house clear-out. It aims to give useful belongings another life, save space and help families check what they own before buying more.

The first six days focus on clothes, toys, books, baby equipment, shoes and accessories, and larger items. On day seven, families choose what to do with everything they have sorted: keep it, pass it on, donate it, recycle it responsibly or sell it.

The challenge was created by Karolina Gudes, a mum of two from Broughton in North Wales and founder of Kidora, a UK family platform built around helping parents buy and sell preloved children's belongings and access family resources.

Karolina said: "Children grow so quickly that a winter coat or box of toys can become unused while still being in great condition. Giving those things another life can help another family and keep them out of the bin."

In March 2026, London's waste authorities launched a School Uniform Reuse Network to help schools organise swap shops and pre-loved uniform schemes, so families can pass on good-quality clothing.

For clothes and shoes, the charity TRAID accepts clean, wearable donations, including children's clothing. It has charity shops across London and offers a free home collection service where available. Parents should check its current collection arrangements and accepted-item guidance first.

For toys and children's books, The TOY Project in Archway accepts suitable new and used items. It asks donors to call ahead to arrange a drop-off time and does not accept baby equipment or children's clothing. Donated toys may support schools, families and community organisations or be sold to fund its work.

These organisations operate independently of Outgrown, Not Wasted, but show how reusing children's belongings can be part of everyday family life in London.

Parents might start with outgrown coats, forgotten toys or spare uniforms. Children can choose favourites to keep and items to pass on.

Parents should take extra care with second-hand baby equipment. Check for wear, damage, missing parts and product recalls before passing anything on, and follow the latest safety guidance. Not all used products are suitable for reuse.

Families do not need to join Kidora, buy anything or list items for sale to take part. The seven-day checklist, posters and ready-to-share resources are free for households, schools, nurseries, PTAs and community groups, and the challenge can be started at any time.
