Infant Swimwear Guide: What to Look for in Baby's First Suit

Choosing your baby's first swimsuit is an exciting milestone, but with so many options available, it can feel overwhelming. Whether you're planning pool time, beach days, or swim lessons, the right swimwear will keep your little one comfortable, protected, and ready for water fun. Here's everything you need to know about selecting the perfect infant swimwear.

Sun Protection is Priority #1

Babies have delicate skin that's especially vulnerable to sun damage. Look for swimwear with built-in UPF (Ultraviolet Protection Factor) ratings of 50+, which blocks 98% of harmful UV rays. Rashguards and swim shirts with long sleeves offer the best coverage, protecting arms and torso without the need for constant sunscreen reapplication in those areas.

Fit and Comfort Matter

Infant swimwear should fit snugly without being restrictive. Here's what to check:

  • Leg openings: Should be secure but not too tight—you should be able to fit a finger comfortably between the fabric and baby's leg
  • Diaper area: Look for suits with a roomy fit to accommodate swim diapers
  • Neck and armholes: Should allow easy movement without gaping or chafing
  • Length: Rashguards should cover the torso completely, even when baby is moving and stretching

Easy On, Easy Off

Changing a wiggly baby is challenging enough without complicated swimwear. Look for features like:

  • Snap closures at the crotch for quick diaper changes
  • Stretchy, flexible fabrics that slide on easily
  • Wide neck openings or zipper closures on rashguards
  • Two-piece sets that make diaper changes simpler than one-pieces

Quality Fabric is Worth It

Infant swimwear takes a beating from chlorine, saltwater, sunscreen, and frequent washing. Invest in quality fabrics that:

  • Dry quickly to prevent chills
  • Resist fading and stretching
  • Are chlorine and saltwater resistant
  • Feel soft against sensitive skin (avoid rough seams or tags)

Consider Your Activities

Think about how you'll be using the swimwear:

For pool time: A simple rashguard and swim diaper or swim trunks work great

For the beach: Full-coverage options like long-sleeve rashguards and swim pants offer better sun and sand protection

For swim lessons: Streamlined fits without extra ruffles or accessories help instructors hold baby safely

Don't Forget the Extras

Complete your infant's swim setup with:

  • A wide-brimmed sun hat with chin strap
  • Reusable swim diapers
  • A hooded towel for warmth after swimming
  • Baby-safe sunscreen for exposed areas

Sizing Tips

Babies grow fast, so here are some sizing guidelines:

  • Check the weight and height ranges, not just age recommendations
  • When between sizes, size up—swimwear should last the season
  • Buy at least two suits so you always have a dry backup
  • Consider buying the next size up for later in the summer

Safety Reminders

While the right swimwear is important, remember that no swimsuit is a flotation device. Always:

  • Supervise infants constantly around water
  • Use Coast Guard-approved life jackets for boating
  • Keep baby within arm's reach at all times
  • Never rely on swimwear for water safety

Making the Most of Your Purchase

To extend the life of your infant's swimwear:

  • Rinse in cool, fresh water after each use
  • Hand wash or use gentle cycle with mild detergent
  • Air dry away from direct sunlight
  • Avoid wringing or twisting the fabric
  • Store in a cool, dry place between uses

Choosing the right swimwear for your infant sets the stage for happy, safe water experiences. Focus on sun protection, comfort, and quality, and you'll find suits that work beautifully for your little one's aquatic adventures.
