Pin the best swimwear for babies of the year.

Swim Diapers

Grow-With-Baby Swim Diapers

Pictured in the style Boho Rainbow, this swim bundle from the Sarah-Jane Collection covers all the basics: It comes with a swim diaper, a matching hooded towel and a wet bag for holding wet swimsuits, diapers, snacks or sunblock. Little ones grow so fast (they need to stop doing that!), and these diapers will grow with them. These swim diapers fit from the infant stage through toddlerhood. By the time your baby outgrows these, they'll be potty-trained! 

Ages: newborn-toddler (10-25 lbs.) 

Available at, $45.95 for the diapers, towel and bag. 

Pair Down to a Swim Diaper

We love these unisex swim diapers from Primary for their cute style and comfortable, snug fit. They boast UPF 50+ to keep baby's bum safe and are free of more than 300 chemicals commonly found in garments. Keep your baby's skin free from irritants with swimwear that doubles as a diaper (like most swim diapers, they only contain waste, not liquid). 

Ages: 3/6 months-18/24 months

Available at, $11.50. 

Stylin' in a Diaper Cover

Keep it simple with this sunshine-print diaper cover from Pottery Barn Kids that lets your baby keep routine in their favorite diaper underneath. Add a monogram to make this simple nylon accessory more snazzy. 

Ages: 3/6 months-12/24 months

Available at, $15.50. 

Boardshorts and Swim Trunks

Quick-Drying Board Shorts

Australian children's wear company Cheeky Chickadee makes clothes with cute, vivid prints. Bonus: They ship free worldwide with orders over $45. We adore these board shorts dotted with hand-drawn cockatoos. They are lightweight so they dry quickly, and they come in larger sizes so siblings (or dad & son!) can go full twinsy at the beach or pool. 

Ages: 6/12 months-10 years

Available at, $19.54. 

Stay-Put Swim Trunks

These swim shorts from MORI sport a snug fit so they stay put when your little paddler makes a splash. Made from recycled nylon and elastane for stretch, they offer UPF 50+ protection. Pair these adorable trunks with a matching rash guard ($34) for extra protection against the sun's rays.

Ages: 3/6 months-3/4 years

Available at, $19. 


Sail Away With a One-Piece

Tiny little sailboats and a billowy silhouette with a tiny ruffle detail keeps baby cute and comfy (and also does a great job of hiding a bulky diaper). This one-piece from Janie and Jack also keeps your little bundle's skin safe with a UPF 50+ fabric. We love that older sibs and cousins can find coordinating prints

Ages: 0/3 months-18/24 months

Available at, $39. 

Twirl in a Skirted One-Piece

If you're looking for solid protection from the sun, check out this line of swimwear from Snapper Rock that blocks 98% of the sun's harmful rays. We love this playful number that features one of summer's favorite fruits along with a sweet, pink skirt. 

Ages: 3/6 months-4 years

Available at, $48. 

Tankinis & Bikinis

Go Seam-Free in a Two-Piece

We're a sucker for a seersucker, and this two-piece set from SwimZip couldn't be cuter. With no seams or tags and adjustable straps, it's the perfect suit for a fuss-free afternoon in the water. It comes in pink, peach and navy gingham; each fabric blocks out 98% of the sun's harmful rays. 

Ages: 6/12 months-5T

Available at, $20. 

Bloom with a Tulip-Back Tankini

A two-piece bathing suit makes diaper changes a cinch. This sweet set from Ruffle Butts features a UPF 50+ seersucker fabric with (naturally!) a ruffled bottom and a chic tulip back (meaning it's slightly open at the waist to show off those ruffles). You can also monogram this swimwear for a super-cute customized look. 

Ages: 3/6 months-4T

Available at, $27.50

Rash Guards

Stay Sun Safe in a Full-Body Rash Guard

When you want all-over protection from the elements, a full-body rash guard is in order. UV Skinz offers an extra layer of protection with a fabric that is certified UPF 50+. This guard comes in three adorable prints: Hibiscus Floral Geo, Peony Pink Geo and Pink Flamingo Dot. For head-to-toe protection, you can also order a matching sun hat

Ages: 3/6 months-3T

Available at, $46.95. 

Make Things Easy with a Two-PIece Floral Set

This multi-floral suit from the Gap really adds a pop of color to a sunny day. A rash guard offers extra protection with long sleeves, but this two-piece option comes with the convenience of a separate bottom. 

Ages: newborn-24 months

Available at, $29.95.

Zip It Up in a One-Piece Baby Rash Guard

This rash guard from Tea Collection features an adorable ruffle leg line and an 80% nylon/20% spandex blend that provides UPF 40+ protection. A front zipper means you don't need to wrestle baby out of a wet suit when it's time for a change. 

Ages: 3 months-4T

Available at, $42.
