Zipped baby clothes for happier families!

Sleep Thief was started by two new mums to bring fun, functional and faff-free clothing to the lives of parents all over the world. And we’re doing this while being kind to the environment and future friendly.

We problem solve. For us, poppers are the worst: easy to rip apart, impossible to do up! That’s why we will only ever use zips where we can.

Our tried-and-tested, rainbow zip placement really does make life easy. With an ankle-to-ankle fastening, we make changing fast and easy. Check out our gorgeous products to see what we mean.

100% Organic Cotton

Sustainability is a bit of a buzz word at the moment, but one which we really care about. We want our little Sleep Thieves to grow up in a world that people care about, and one where we as parents are making the right decisions.

That’s why all our products are 100% organic cotton. This raw cotton is sourced in Turkey and approved by the Global Organic Textile Standard (GOTS). All our dyes are kind to babies and the environment as they are OEKO-TEX® Standard 100 certified.

UK Born & Bred

We are very proud that all our clothes are designed by us in London and made by our ‘Extended Family’ in the UK.

This ranges from our factory and fabric dyers in England to our pattern cutters and photographer. Each one of these people has played an important part in the Sleep Thief story.

The Bigger the Better

Our sizing is on the larger size of the baby-clothing spectrum. 

We believe in the longevity of clothing and don't want you to have to rush to buy another Mischiefsuit within a couple of weeks of buying your first one!

Our 'footens' also add length to the leg. Once your Sleep Thief's feet are too big, the footens simply become an addition to the leg and can stop at the ankle.

Our Sleep Thief models pictured are both nearly 2 years old and are wearing size 18 - 24 months with footens gathered at the leg. Also, these suits have not been washed yet and we allow for 10% shrinkage, due to the nature of organic cotton, hence the baggy trouser brigade!

Why the zip location?

Our 2 most frequent questions are

"Why doesn't the zip go down the front of the suit?" and "Why don't you add a zip to the front as well as on the legs?"

It's quite simple. We haven't added a zip on the front because we want your little ones to be comfortable.

We don't want a zip annoying them around their neck or pressing into them on their fronts.

And we don't have the zip on the front because that's what annoys us about the current zipped babysuits on the market.

They go down one leg, making it a hassle to remove and replace the other leg. Most also only have a one way zip too, meaning you have to undo the whole babysuit even for a nappy change.

We have come up with our innovative design for faff-free fun times with your Sleep Thieves!
