The Best Baby and Toddler Swimsuits (2026 Guide)

Summer is right around the corner, which means baby and toddler swimwear are starting to pop up everywhere. From one-piece and two-piece sets to rash guards and toddler sunglasses, there are so many cute options to choose from. 

When shopping for baby and toddler swimsuits, comfort, fit, and sun protection matter just as much as style. Trust me on this! Features like UPF 50+ fabric, easy diaper access, and designs that stay put during play matter. They can make a big difference for long days at the pool, beach, or splash pad!

Here are our top picks for swimsuits that your babies and toddlers will WANT to wear without fussing AND offer great sun protection.

Best Swimsuit Colors for Kids

Before we dive in (get it?!), here’s a quick but important note on choosing the best swimsuit colors for kids.

When it comes to swim safety, color matters more than you might think. Bright, neon, and high-contrast colors are the easiest to spot in the water—especially in pools and open water. Think about the bottom of a pool, which is usually a light blue. If your child is wearing a similar shade or muted tones like gray, tan, or pastels, they can blend in and be much harder to see.

Choosing bold colors like neon orange, green, pink, or yellow can help your child stay more visible, giving you extra peace of mind during swim time.

What to Look For in a Baby Swimsuit

When choosing a baby swimsuit, the big priorities are sun protection, easy changes, and comfort!

• Easy on and off – look for front zippers, stretchy neck openings, or two-piece sets that still offer good coverage 
• Diaper access – look for snaps at the bottom, two-piece sets that still offer good coverage, or zippers that allow for easier changes 
• Full coverage for sun protection – look for long sleeve swimsuits, high necklines, full body sets, or rash guards; UPF 50+ fabric is ideal 
• Comfort – check the seams and tags to ensure they wouldn’t rub; look for soft and stretchy quick-dry fabrics to prevent irritation

What to Look For in a Toddler Swimsuit

For toddlers, the priorities shift slightly from babies. We look more for mobility, visibility, comfort, and sun protection.

• Easy on and off – continue looking for zippers, stretchy neck openings, or two-piece sets
• Diaper access if needed or quick access for the bathroom – if your toddler is still in diapers, getting something with snaps is still ideal; for potty trained toddlers, look for two-piece sets to make it easier for your child to navigate in the bathroom!
• Comfort & fit – look for tagless options, soft seams, and stretchy material that provides good coverage
• Visibility – since toddlers are more on the move, you want to be able to spot them easily! Opt for bright, neon and contrasting colors for safety
• Sun protection & coverage – look for UPF 50+ protection and long sleeve swimsuits for added protection from the sun’s rays
