Pieces need to be long-lasting, durable, wash well and have the potential to be passed on to future siblings (The Independent)

With the average baby going through approximately 4,000 nappies before they’re potty trained and each nappy taking more than 300 years to break down, it’s easy to feel like feeding, watering and clothing your offspring finds you on a slippery slope to landfill bedlam.

With the mounting concern that we’re destroying our planet for future generations, and with thousands of microscopic fibres entering rivers and oceans with just one single clothes wash, now more than ever is the time for households to up their green status – so, to kick things off we’re looking at kids’ wardrobes.

According to the Waste and Resources Action Programme (Wrap) more than 300,500 tonnes of clothing end up in UK landfills every year. This needs to reduce massively and a good place for parents to start is by buying clothes that are designed to last.

Of course, sustainability encompasses many things; from reducing the environmental impact of production processes, cutting out harmful chemicals, and ensuring ethical guidelines are in place when it comes to safe working practices in factories, and workers getting paid fairly to do so. But when it comes to dressing kids, sustainability means quality too.

Pieces need to be long-lasting, durable, wash well and have the potential to be passed on to future siblings, so it’s important for parents to buy with longevity in mind.

To inspire your next purchase to be that little bit greener, we’ve picked out the best sustainable brands, highlighting our favourite pieces which have all been given the seal of approval by our mini testers.

Muddy Puddles sunsafe rash vest and bottom set

In the fight to protect the oceans with sustainable fashion, this year British children’s brand Muddy Puddles launched UV protective swimwear and it’s made a huge splash with us. Made entirely from recycled plastic bottles, the Save our Oceans collection is the perfect beach wardrobe for this summer’s keen mini-surfers, rock-poolers and sand-castle builders, taking design inspiration from the world beneath the waves, with mammal prints, vibrant colours and thought-provoking slogans.

IndyBest pick: Muddy Puddles sunsafe rash vest & bottom set

We tested the surf suit, swim shorts and rash vest and bottom set and they were all a hit. The built in UPF 50+ means they can play safely, and we loved the high neck and full-length sleeves for fuller sun protection, while the “recycle to save me” slogan incorporated in the fun whale design is eye-catching. With prices starting from £15 the collection won’t cost you a fortune either.

First known for its natural and sustainable skincare products – from eco nappy subscriptions made using chlorine-free fluff pulp to hypoallergenic baby moisturisers – so when the brand launched its babywear line, it could only follow the businesses’ conscious ethos, and we’re very impressed. The 100 per cent organic cotton babywear range is not only completely adorable, it’s also helping to conserve rainforests and fund healthcare clinics women in Sierra Santa Cruz, in partnership with the World Land Trust– a British charity dedicate to the conservation, protection and sustainable management of natural biosystems and biodiversity.

The cardigans currently go up to 18-24 months, but we would love to see these in larger sizes.

The verdict: Sustainable kids' clothing brands

You can’t deny the efforts that brands are going to, to make its businesses more sustainable, and teaching this to our kids is paramount. Muddy Puddles save our oceans collection really impressed us – particularly the sunsafe rash vest and bottom set – in terms of quality, fabrics, eco messaging and still keeping costs affordable. We also love the green thinking of The Bonniemob and has to be applauded for introducing zero d printing to the kids’ market, and we were impressed with the kids denim-look shorts.
