1. Gerber Unisex 5 Pack
Stretchy, breathable material
Unisex design for all genders
Sizes to fit up to 24 mos.
Five-pack for variety
One design may make parents hesitant
We can’t think of any baby that wouldn’t look positively adorable sporting a cute bear onesie. Once again, Gerber comes to the rescue with their 100% cotton onesies, but this time, it’s unisex and fits babies up to 24 months!Read more
It’s sometimes difficult to find separate pants, shirts, skirts, dresses, etc. to fit your baby when they don’t immediately grow according to their age, and that’s when onesies save the day. While most stop sizing at 12 months, parents can take comfort in the fact that Gerber offers extended sizing for those babies who are either fussy and don’t want real clothes yet or just aren’t growing as quickly as others.
These Gerber Baby onesies are made from 100% cotton. They stretch easily to make it over Baby’s cute little pumpkin head and feature a metal snap closure on the bottom for fast access during diaper changes. The snap is positioned strategically higher on the onesie for optimal convenience.
There are 35 different packages you can choose from. --You read that right: thirty-five. Each set contains five varied onesies. That’s five different designs times thirty-five sets...leaving you with 175 different onesies. Some of our favorite themes include Love You Kitty, New Duck, Princess, Fox, and Animal.

Bottom snap closure
Nickel-free, and made with soft material

Ignore the “Boys” tag on this; exempting one or two options that specify gender, little girls and boys can both rock these with equal flair. Each set includes six varied machine-washable onesies with snap closures and expandable shoulders.Read more
The expandable shoulders allow you to pull the onesie down and off of the baby, in case they make a mess and it’s too much of a hassle to try to bring the bodysuit up over their head. The snaps at the bottom make diaper changes easy, and the variety of designs means even if they make a mess of one, there are five more in the set for them to model.
Carter’s Simple Joys Boys’ 6-Pack featured short-sleeved onesies of varying materials. Fabrics change based on size and design but are largely cotton with nickel-free snaps.

Marvel has taken the world by storm, and we like that they’ve included babies in on that action-packed adventure. Everyone has a favorite superhero, and eventually your baby will, too in these soft, super bodysuits!
The blends of materials that these onesies are made from making them more durable than the standard blend. It is a blend of fabrics that provide the onesie with a cotton and polyester blend. Polyester blends provide a more breathable design and do not shrink during washing.

Criteria Used for Evaluation
Babies can be fussy. They might not care what they look like (or if they do care, they can’t articulate that) but they certainly care how comfortable their clothes are. We suggest straying from itchy, scratchy fabrics as much as possible, and investing in styles where hardware like buttons and snaps won’t irritate sensitive baby skin. Many of these items are made from organic cotton and all of them get softer with continued use. Make sure you consult the sizing guides to ensure that your little pea is properly fitted and not constricted by their onesie or swimming in it! And consider investing in a natural detergent or one meant for babies, as the wrong kind of soap can cause reactions in infants and toddlers.
The reason we had listed (mostly) 100 percent cotton onesies, is because it is non-allergenic. When dealing with a newborn baby, we think that the least reactive fabric is the better route, which is why any onesies listen above that are a cotton blend, tend to lean towards older baby ages. Just like going organic, the type of fabric you choose to wrap around your baby is your own. Our goal is to help you make the best choice!
Truly, you’ll never run out of options when it comes to baby clothes. Onesies especially are a staple in many baby wardrobes and so have all kinds of fun and funky designs to choose from! We know sometimes the most overwhelming part of shopping is the sheer amount available to you. We’ve made sure all of our choices come highly recommended for many reasons, including their stylishness. We’ve also made an effort to include some variety so there will be a little something for everyone. We’ve got your long sleeves, we’ve got your short sleeves, we’ve got your sleeveless! We’ve got awesome superhero designs and understated colors with cute sayings--we’ve even found a pack of plain ol’ white onesies!
We know your baby is the most important person in your life, and we want you to know that we care, too. Plenty of research went into picking out not only the right onesies but the reasoning behind why they are right for you and your baby. From styles, to ease of changing, to fabric makeup and flexibility, we’ve thought about it all.
Clothing your child shouldn’t be something to stress over, and we’ve tried our best to make it a fun and unique experience, by finding a onesie that suits every fashion style and lifestyle. Here you'll find the listed criteria that we’ve used to carefully and thoughtfully select every onesie we’ve listed above, and we hope that you’ll be as satisfied with the results as we are.
Other Factors to Consider
When it comes down to it, going organic is similar to going “green.” It’s a personal choice within your family, and whether one is better than the other depends on a parent’s level of comfort dressing their baby in certified organic fabric or fabric that is 100 percent pure, but may not be organic. To us, there is no right or wrong here–just a personal choice, and we are happy to provide both options for a happy family and an even happier baby. Our list was comprised of the best onesies in both categories so that neither was left more superior than the other.
Frequently Asked Questions
q: Do the variety-pack onesies come with all the colors/designs shown in the pictures?
Yes, all variety pack onesies are true to the images that are shown.
q: Are these all 100 percent cotton?
All the onesies listed are 100 percent cotton unless otherwise specified in the Pros/Cons or Benefits sections.
q: How should I wash this outfit?
Most cotton, as well as blends, are safer being washed in cold water to avoid shrinking, fading, discoloration, and general wear-and-tear. All can be machine washed.
q: My daughter weighs 16 pounds, what size would you suggest?
All onesies differ based on the maker and size range. Sizing charts are available, the general rule is to go a size or two up just in case.
q: Why are onesie one of the safest sleepwear for newborn babies?
Onesies are great sleepwear for newborns because of the ‘fit’ design. Babies who wear clothing that is too loose when they are sleeping run the changes of SIDS. One piece designed outfits with a built-in secure closure system helps avoid the ride up over their face.
q: Should I buy a few sizes bigger than what my baby wears?
Yes, please do. If you buy the next one or two sizes up from what your baby wears this will give optimal wear time and save on your expenses. Babies grow rapidly and often times you can buy clothing a bit bigger and work with it until it is too tight to wear anymore.
