The Best Swim Gear for Babies, According to Swim Instructors

Summertime usually means spending a lot of time at the pool or the beach. If you have a baby, you’ll most likely want them to join in on the festivities (especially if there’s a kiddie section at said pool or beach). And that’s a good thing, according to the swim instructors we spoke with, who told us that the best way to encourage a love of water is to get little ones in it as soon as possible, so they’re comfortable by the time you can sign them up for more formal lessons (which the folks we talked to highly recommend, as drowning is the second-leading cause of death among children ages 1 to 4 years old, according to the Centers for Disease Control.)

Luckily, it doesn’t take much to introduce babies to water (hello, bath time!), and there are programs all over the country that can help when your kiddo is ready to go from tub to a bigger pool. There is also a lot of gear — including swim diapers, wetsuits, and even toys — to help make that first dip fun enough for your little one that she’ll want to go back for more, according to our experts. Read on for the best things that our pros — among them Jim Spiers, CEO of New York City– and Houston-based aquatics education program SwimJim; Heidi Reiss, a co-owner of Brooklyn-based kids’ swim school Aquabeba; Brendan O’Melveny, chief aquatics officer and baby swim specialist at Imagine Swimming; and Mary O’Donoghue, senior aquatics director at the YMCA of Greater New York — recommend using to introduce babies 36-months-old and younger to the water.

Best overall swim gear for babies

Depending on the program, babies can start swim lessons as early as 2 months. At this age, they’re not exactly swimming, but rather — along with their parents and caretakers — learning to be comfortable in the water. All a baby needs to get started is a pair of reliable swim diapers and a swimsuit, which together are crucial for keeping fecal matter contained, our experts say. (If poo does escape into the pool, it has to be shut down for health reasons.) Three of our experts recommend reusable swim diapers, and both O’Melveny and Reiss prefer ones by Finis. “Swim diapers should have stronger elastic around the waist and thighs. The less openings, the better,” says Spiers. O’Melveny agrees that Finis diapers work well: “They’re simple, effective, and have a wide range of sizes, colors, and prints to choose from.”

When it comes to swimsuits, Reiss and O’Melveny say you don’t necessarily have to get your baby a traditional one if you get a good swim-diaper cover, like a Happy Nappy from British company Splash About — which Reiss requires young swimmers to wear at Aquabeba lessons. “Splash About has the best product on the market to date,” says Reiss. “It is made of neoprene and fits over the swim diaper. It’s secure around the waist and thighs to lock everything in.” O’Melveny agrees, saying that the wide bands keep everything solid from getting into the pool, which in turn keeps water (and swimmers) healthy. Reiss also likes that they look like bathing suits, and says they’re even good for older babies who might be potty trained, but still have to wear a diaper in the pool, and might not be thrilled about that. “Children forget to use the bathroom when they get into the water,” she says. “They need that layer of protection, and because it mimics a swimsuit, it’s not stigmatizing or traumatizing.” The Happy Nappies come in a bunch of fun prints and colors in sizes from newborn up to 3 years.

Best disposable swim diapers

Two of our experts say using disposable swim diapers is also fine (as long as they’re covered by a swimsuit), noting all the major brands make them — like this inexpensive set from Huggies. Reiss says you could even put a disposable one under the Finis diaper if you’re really worried about accidents in the pool. Regular diapers, however, should not be used under any circumstances, according to our experts. Because they are designed to absorb liquid, they will become bloated in the water and eventually erupt, spilling gel beads everywhere. “Swim diapers do not have that,” says Spiers. “They’re literally just to contain any kind of fecal accident, and not necessarily the urine and stuff like that.”

Best wetsuit for babies

While the swim instructors we spoke to say they try to keep the water temperature warm enough to be comfortable for young children — around 90 degrees at Imagine Swimming, for instance — sometimes that isn’t possible, especially if it’s a shared public pool. “Most pools are much colder, and a wetsuit can be really helpful,” says O’Melveny. So if you want to put your baby in wetsuit for more coverage, he recommends one by Warm Belly. But, he cautions, “if you have a warm pool less is more,” because “if their bodies are all covered, they don’t get the tactile sensation of being in the water,” which he says offers all kinds of neuromuscular benefits, especially to infants. “They get so much more feedback from the water [than when they’re moving] in the air,” he says. “We generally recommend getting them in the pool with a diaper and diaper cover, but if the water or air is cold, it’s better that they’re warm enough to stay in the water for more than a few minutes.”
