7 Best Swimsuits for Babies and Toddlers

Getting your baby comfortable in the water means using the right swimsuit. Here’s a breakdown of our favorite swimsuits for babies.

Water literacy is one of the most important things your baby will learn. Part of the process of becoming a little swimmer is wearing the right baby swim gear.

When picking out the right swimsuit for your baby, there are a few things you want to keep in mind when it comes to functionality:

  • Coverage from the sun. During the summer months, whether you are at the beach or lounging around in an inflatable kiddie pool, the sun is beating down in a big way. The soft skin of babies is especially prone to sunburns, and while sunscreen is an effective screen, blocking some of the sun’s harmful rays, a swimsuit with coverage provides an actual sunblock.
  • Space for swim diapers. The swimsuits in this collection do not include swim diapers, which is something your little swimmer will need when hitting the water, whether it’s your backyard above ground swim pool or the neighborhood water park. (Check out our full breakdown on the best swim diapers for your baby)
  • Quick-Dry, Comfortable Fabrics. Look for swimsuits that are high in polyester. This is a durable, long-lasting fabric that also dries relatively quickly and that is hypoallergenic and sits comfortably on the skin of your baby. Swimsuits or clothing that is perpetually soggy can ride and chafe, making those swim sessions and the time after uncomfortable.

Of course, there are other things to consider, such as price and style, but those three are the basic functionalities every baby’s swimsuit should check off.

Below is a collection of my favorite swimsuits for babies, whether you are looking for your baby boy, baby girl, or something unisex.

Baby Swimwear – FAQs and Buying Guide

What should I look for when shopping for baby swimwear?

Ultimately, the baby swimsuit you choose should align with what you want for your child.

Here are the key things to look for:

Sun protection.

Because babies have such sensitive skin, sheltering them from extended UV exposure is critical. The best way to help protect them is to cover them up.

Sunscreen and sunblock have a place, for sure, but the surest way to reduce sun exposure is simply covering them. Most swimwear for babies is not like your traditional one-piece swimsuits or swim briefs, exposing shoulders and back to the sun.

Temperature regulation.

Swimsuits provide a layer that can warm up a toddler in the pool (wetsuits for toddlers are a great example of this) and also keep them cool in warmer environments.

The amount of coverage the swimsuit has plays a role in how cool/warm your baby will be. Swimsuits made of neoprene (the same material found in open water swimming wetsuits) are especially warm, with a solid layer of insulation, making them perfect for cooler aquatic environments.

Materials and fabrics.

Swimsuit fabrics generally fall into a couple of categories. Durable fabrics like polyester and nylon reduce excess stretch and thinning and hold the swimsuit’s color over time. Stretchy fabrics like elastane (also known as Spandex or Lycra) give the fabric stretch for a snug and comfortable fit, but don’t last as long.

While there’s something to be said for ballin’ on a budget and getting the cheapest suit you can find, often the stitching and seams on cheap swimsuits are ragged and flimsy, chafing your baby’s skin.

Your baby’s swimsuit is an investment, and choosing a quality baby swimsuit will only encourage both of you to hit the water more often.

Bathing Suit for Babies

Does my little swimmer need to wear a swim diaper with a bathing suit?


Swim diapers are a necessity when taking your baby to the pool or beach. They are an oft-misunderstood piece of the puzzle when it comes to baby swimwear, and parents will often use a regular diaper.

But swim diapers, while they don’t hold pee, will keep doo-doos in the pool and out of the swimming pool.

Swim diapers don’t balloon out when they get water-logged. They are designed for extended use in the water, and they are usually made with fabrics that don’t chafe the soft skin of your toddler when wet.

Regular diapers soak up all of the liquids they can find (pee or not), and in a pool, this form of diaper will quickly become an anchor for your baby and toddler.

There are two kinds of swim diapers:

Disposable swim diapers. As you can probably guess, baby wears it once and then it finds its way to the garbage. While they look a lot like regular disposable diapers, they are specifically designed to not get water-logged with fluids. Available in both pull-down and tear away.

Reusable swim diapers. Usually available as a pull-down or with snaps or Velcro closures on the sides, reusable swimming diapers have a soft mesh on the inside and can be cleaned after use (note that most swim pools do not allow you to clean the diaper in the sinks in the locker room).

There are lots of benefits to both, but ultimately you want a swim diaper that matches the needs of your child.

Baby Swimsuit Buying Guide

What swimwear do children need by age?

Babies are growing quickly, and as they grow, the swimwear they rock out in at the pool will change. What a three-month-old will need will be different than an 18-month old.

Here’s a generalized age-by-age breakdown of each age group and recommended swimwear:

0-3 months. At this age, the big priorities are keeping your baby warm and being mindful of sensitive skin. Newborns have particularly sensitive skin which can get irritated by chafing of the swimsuit. They also feel the chills easily, so look for swimwear that is soft on the skin and will keep them warm while in the water. Thermal baby swimwear is worth a look for particularly chilly pools.

3-6 months. At this age, your baby is starting to get a little adventurous with their arms and legs, so look for a swimsuit that gives them excellent range of motion while also keeping them nice and warm (and comfortable!) in the water.

6-12 months. As your baby continues to grow, they will find themselves getting more comfortable in the water and will be eager to test out their splashing skills for longer. Extended periods of time in the water mean an increased likelihood of accidents, so diaper up. As toddlers are getting wiggly and splashy, a baby swimsuit that is made of neoprene is an excellent choice for both keeping them warm and giving you a good grip on your baby.

12-18 months. Okay, now baby is starting to exert some independence. Toddler swimsuits with floatation devices in the suit are a good choice for babies this age. (Floaties for toddlers do not replace proper supervision in the water.) Swimwear at this age should encourage more confidence and help your toddler learn how to float in the water.

What is the best kind of baby swimwear for outdoor pools and the beach?

There’s not many things better than lazy summer days hanging out by the water, whether that’s a backyard pool (these inflatable kiddie pools are worth a look for a low-cost way to cool off for adults and kiddos alike) or the water-s edge at the beach.

But with the great outdoors comes some added concerns when it comes to choosing the right swimwear for your baby.

Swimwear that doubles up as UV protection is an excellent bonus. Rash guards are ideal for warmer days at the beach where baby wants to avoid overheating while blocking the sun.

For cooler days, there are plenty of wetsuits for babies and toddlers that regulate your baby’s body temperature while also blocking UV rays.
