What is the difference between a Toddler romper, onesie, and coverall?

Ever wonder why you can’t seem to remember every baby terminology when you go baby clothing shopping? Although it may seem terribly complicated, brands love to call baby clothing different names, causing new moms like you to be confused about which is which.

You already have enough on your plate, having to take care of a new infant, and the last thing you need is unnecessary confusion in your busy lives. However, we are here to debunk your worries and teach you that many baby clothing items you may know are called something you thought was something different. 

Toddler Rompers vs. Jumpsuit

A toddler romper, also known as a jumpsuit, is similar to a onesie, but has more leg and arm room to keep your infant covered. It is usually worn by newborns and toddlers and can range in many different prints and styles. Rompers are usually designed with the intentions of making it easier to take it on or off, and quicker diaper changes, making it convenient for parents when your toddler is at home or on a family stroll in the park.

With Free Birdees, they have a wide selection of toddler romper patterns ranging from Heavenly Pink Unicorns to Blue Lagoon Rhinos. Free Birdees’ rompers also include snaps along the left shoulder to make it easier for parents when changing your toddler.

Being one of the best bamboo baby clothes Free Birdees has to offer, they have an amazing selection of toddler rompers for all ages, including toddler boy rompers 2t and toddler rompers 3t, and the cutest toddler romper patterns! By age four, toddlers are transitioning to other clothing, so finding sizes of toddler boy rompers 4T are usually not available.

Maybe you already have heard of this, for it is something all ages have adopted to wearing. However, be aware that an adult onesie is fairly different from a baby onesie. A baby onesie, a huge staple in your toddler’s closet, is similar to a t-shirt, but can be sleeveless, short/long sleeve.

In addition, most baby onesies have a snap up crotch flap to make diaper changing easier for parents. A baby onesie can also be referred to as a bodysuit, side snap bodysuit, or a creeper. For the most part, toddlers wear a onesie to conceal their diaper and to wear something adorable and comfortable!


Although coveralls are still a one-piece, there are some major differences compared to baby rompers and onesies. For one, it completely covers your toddler’s body, hence the name “coverall”, and it usually has a zipper or snaps down the center. Coveralls are usually worn as baby pajamas, but can be used as an in-house outfit or play outfit right after nap time/bed. It can also be known as a sleeper, pajamas, and one-piece footie.

In Free Birdees’ collection of bamboo coveralls, they offer over 20 different prints to make sure there is something for everyone. It comes with a zipper across the whole body making diaper changes and outfit swaps a breeze!

Not to be confused with Free Birdees bamboo footies, their bamboo footies are the exact same thing as their coveralls except there are anti-skid footpads. Therefore, you can make the choice of whether your toddler likes to feel the floor with their bare feet (coveralls) or want the extra padding on their feet (footies).

What is the difference between a jumpsuit and toddler romper?

Again, this can be a questionable subject when we are talking about the differences between a jumpsuit and a romper. There are a few differences between the two, however, some people and brands may associate a jumpsuit and a romper to be the same thing, for they are very similar.

By definition, a romper is considered a type of jumpsuit; therefore, rompers can be jumpsuits but not all jumpsuits can be rompers. Despite their similarities, we will explain the differences there are to distinguish the two, and you can make the choice if you believe they are synonymous or two different items. 


There are many ways to define a jumpsuit. However, for toddlers, jumpsuits are considered a one-piece type of clothing. It is a one-piece garment consisting of a blouse or shirt with attached trousers.

In addition, jumpsuits can come in many different styles, including full-length sleeves, full-length pants, half/mini sleeves, short sleeves, short pants, etc. However, the one thing similar to all these styles is both pieces are attached (one-piece). 


If you were wondering if a romper is a jumpsuit, then yes, you can consider a romper a type of jumpsuit. Whatever you call a romper, just know it consists of a shirt and shorts. By definition, a romper can be considered a one-piece or two-piece combination of shorts and a shirt. However, in today’s fashion world, it is considered a loosely fitted, one-piece garment combining a shirt/blouse and shorts worn by young children.

Rompers can also come in many different styles including toddler long sleeve rompers. In the end, rompers and jumpsuits are commonly used as interchangeable terms, for they serve similar purposes and are both one-piece clothing. However, most true rompers are not full pants (short/ short length skirts). You can be the judge to decide whether the few differences make them different baby clothing.
