Sleep Thief

Sleep Thief creates fun, functional, faff-free children's clothing, all with the aim of making the lives of parents, carers and children easier.

The company was founded by mum-friends Effie Dower and Sophie Swallow who recognised the need for innovation in baby clothing. Both Effie and Sophie were constantly annoyed by poppers and heard the same complaints from parents everywhere they went. So, Sleep Thief was launched with the aim to create parent-approved, popper-free baby clothing.

Sleep Thief's launch item - the Mischiefsuit, a zipped babygrow - showcases a unique zip placement, is made from 100% GOTS certified organic cotton and has foldable feet, while proudly being designed and manufactured in the UK.

Sleep Thief's look is fun, fun, fun. They think that life needs to be lived lightly and happily, that clothes can be cute and cool, that clothing brands can be creative and caring. This runs through the veins of Sleep Thief: from its branding to our products, there is a sense of playfulness and fun, just like babies the world round.

Sleep Thief are also passionate about the environment that we live in and the world we are leaving to our children. They focus on future-friendly fashion by using certified organic cotton and OEKO-TEX Standard 100 dyes and zips, which are kind to your kiddies and the planet. By using these materials, Sleep Thief creates clothes with longevity that can be passed from child to child, and hopefully generation to generation!

Being made in the UK, Sleep Thief has amazing relationships with the people in their network and manufacturing process, and work every day to improve this and promote the hard work they do. By doing this Sleep Thief are also minimising their carbon footprint by keeping distances travelled to an absolute minimum.


Our products are all manufactured, dyed and embroidered in Leicester.
