How to Choose the Perfect Swimwear for Your Child?

The first trip to the pool with your little one is a big and exciting event for every parent, opening the door to a wonderful adventure with swimming. Before you pack your bag, however, you'll need to tackle the challenge of choosing the right swimsuit that will give your child maximum comfort and safety.

What to keep in mind when choosing swimwear for your child?

Choosing your little one's first swimsuit is an important task that affects their comfort, safety and willingness to learn to swim. When putting together a pool kit, it's best to focus primarily on your child's comfort and the quality of the materials, rather than just the look of the clothing.

  • The right size is essentialDon't buy swimwear "to grow into" – overly loose swim shorts can slide off, while a suit that's too tight will pinch and cause painful chafing.

  • Material quality and safety – Choose certified fabrics (e.g. OEKO-TEX®) that are free from harmful substances and safe for your child's delicate skin.

  • Bright colours for safetyNeon shades (yellow, orange, bright green) make your child far more visible in the water and on the beach, making it easier to keep an eye on them and improving safety.

  • Easy to put onChoose models with practical zippers or snap fasteners at the crotch, which make quick nappy changes and undressing easier without unnecessary tears.

Why shouldn't a child be naked at the pool or on the beach?

Letting your little one go without clothes at the pool or on the beach carries serious hygiene and health risks. The delicate skin around a child's intimate areas is extremely prone to bacterial infections, irritation and minor injuries caused by sand or rough surfaces.

In addition, public pools have strict sanitary rules that require the use of special swim nappies to prevent embarrassing "accidents". Appropriate swimwear, especially in the open sun, also provides an essential barrier against harmful UV radiation.

What features should the perfect pool swimwear have?

Good swimwear has to cope with specific conditions such as chlorinated water and intense sunlight. Here are the most important features you should look for before buying:

Swimwear feature

Meaning and benefits for your child

Quick-drying material

Protects your child's body from sudden chilling after leaving the water and prevents irritation.

High elasticity

Ensures the material fits the body perfectly and doesn't restrict movement during water play.

No rough seams

Flat, soft finishes prevent painful scratching and chafing of delicate skin.

Chlorine and salt resistance

Guarantees that the swimwear won't lose its properties or vibrant colours after frequent washing and swimming.

UV protection (UPF 50+)

Blocks harmful sun rays, which is crucial during play at open-air pools and on the beach.

What is the best swimwear for a baby, and what for an older child?

A child's needs change very dynamically along with their age and motor development. The youngest babies can't yet regulate their body temperature on their own, so they need proper warmth during their first swimming lessons. Older, more active children generate heat through movement, so in their case freedom of movement and support in learning to swim become key.

Child's age

Recommended type of swimwear

0-3 months

A thick neoprene wetsuit (e.g. with a fleece lining) covering the arms and legs, combined with a swim nappy, protecting against rapid chilling.

3-6 months

A neoprene "wrap"-style wetsuit (Velcro fastening) or a suit without legs. The child starts to move more, which helps them stay warm.

6-12 months

A classic double nappy system (reusable nappy + insert/suit) or a lightweight wetsuit, adjusted to the water temperature at the pool.

Over 1 year old

Classic swim shorts/trunks for boys or one-/two-piece swimsuits for girls. It's worth considering swimwear with a built-in buoyancy system (e.g. a float suit) to help with learning to swim.

Extra accessories: what comes in handy at the pool or on the beach

Putting together the perfect pool set goes beyond just choosing swimwear. Here's a list of incredibly useful extras that will give your child full comfort and safety by the water:

  • Swim nappies An essential item for little ones who aren't potty-trained yet – they effectively keep messes inside and don't soak up water.

  • Swimming goggles Protect sensitive eyes from stinging chlorine and prevent fear of accidental splashing to the face.

  • Swimming cap Required at most pools; fabric models are the most comfortable for children as they don't pull the hair when being put on.

  • Earplugs Protect against water getting into the ear canals, minimising the risk of a painful ear infection after swimming.

  • Hooded towel or poncho Perfect for quickly wrapping up and warming your little one right after they leave the water, protecting them from the cold on the way to the changing room.
