Difference Between Onesies and Sleepers

Our onesie and sleeper guide gives you the lowdown on newborn naptime 'fits.

What is a onesie?

A onesie is an infant and young baby one-piece they can wear both day and night. Made from soft, comfortable fabric, it features a roomy envelope neckline for ease and snap or zipper closures for quick outfit and diaper changes. Yay! Our onesies are made from cotton, recommended for newborns to protect their sensitive skin from irritation. It also helps regulate your baby’s fluctuating temperature because it's much more breathable than other fabrics. We have a collection of onesies with covered feet and padding on the soles for when baby is ready to crawl, so their tootsies are protected from the floor.

Onesies For Preemies

Specifically designed for babies who are 3lbs, 4lbs and 5lbs, our premature baby collection has onesies with flat seams for extra comfort, soft self closures and the ability to open flat for easy changes.

What’s the difference between sleepers and onesies?

"Sleepers" and "onesies" are used interchangeably, since they’re basically the same thing. But a sleeper usually has enclosed toes, making it what your baby will be most likely to sleep in. Sleepers with mittens are a great idea to cover their hands when it's cold out. It's also handy to have both footless and covered foot picks for changes in seasons and environments.

Types Of Onesies and Sleepers

Zip-Up Onesies

Babies look cute whatever they wear. But if you want to make your life easier (when half asleep), a zip-up onesie makes changing them so much easier. And it looks adorable, too... Having the zipper at the front instead of at the back (like adult's clothing) means you don’t need to turn them over when they’re on their mat, making it a lot easier to change diapers. Winning... We have lots of zipper onesies in different textures and animal prints, from newborn sizes to 12-18 months. Trust us, you’ll go gaga for them...

Zip-Up Sleepers

A zip-up sleeper is a practical pick. You'll find zippers on cotton as well as fleecy sleepers. Usually found on the middle of the sleeper, it goes across the length of the baby. Messy mealtime? No one will know: You can have them in and out of one of our sleepers in the time it takes them to gurgle. Grandma, Grandpa and other guests will find baby spic 'n span and ready to cuddle.

Mitten Sleepers

Another feature new parents will love? The mitten sleeper. Babies are kept safe from scratching themselves or you with their nails (which can be sharp). A mitten sleeper will also have covered feet to keep baby’s hands and toes toasty when out in the stroller.

Footless Sleepers

A footless sleeper is an infants and toddler one-piece that covers the body from the neck to the ankles, leaving their feet uncovered. Those little feet will get hot in summer, so it's the perfect time for footless picks. Just like covered ones, they come with zippers, buttons or snaps. 

Zipper Or Snap Sleepers?

Can't decide about zippers or snaps? Your baby probably won’t have a preference at this stage, so let’s talk through both onesie styles so you can figure it out. Onesie zippers usually start at the neckline, go across the body and end at the leg. Snaps also open at the neck and go down the seams of both legs. It's up to you which you pick to put your tot in: both are easy for them to wear. Having a mix of both is a good idea, because you'll need lots; that's why we have onesie multipacks.

FAQs

What’s the difference between onesies and sleepers?

There’s a clear difference between a bodysuit and a sleeper, but not between a sleeper and a onesie. Bodysuits are like a cousin in the babywear family, with snaps and no leg coverings. Sleepers and onesies are like sibs or fraternal twins: sleepers need to cover your baby’s feet or hands.

How many sleepers does a newborn need?

Babies sleep a lot, so make sure you have plenty of sleepers to change them into for their nap after feeding, bathtime and burping. We recommend you have around six to eight to rotate each day. Older babies or toddlers might not need as many changes, since they start to get into a routine and wake up less in the night.

How many onesies do I need?

It's always good to have a few onesies handy: newborns' temperature changes and you’ll probably have to change their sleeper or onesie at least three times a day. We recommend you have around six to eight onesies, and we have multipacks in twos and threes. They’re easy to machine wash and can go in the dryer and be ironed.
