Set with sun hat or swimsuit on its own
- Swim set: swim bottoms or bloomers with a matching UPF 50+ sun hat. The most complete option for first trips to the beach or pool.
- Knitted swimsuit: simpler, to pair with a hat you already have.
Sizes for the first months
Babies grow very quickly: 59–62 cm is size 1-3 months, 63–68 cm is 3-6 months and 69–71 cm is 6-9 months. If summer falls between two sizes, choose the larger so it lasts the whole season.
Sun and babies: common sense
A UPF 50+ sun hat helps cover the head but is no substitute for shade. Avoid the middle of the day, keep baby in the shade most of the time and ask your paediatrician about using sun cream at this age.
Is it suitable for baby swimming?
For baby swimming classes or the paddling pool, check the swimwear fits over a swim nappy without being tight. If in doubt, the next size up is usually the most comfortable.
Frequently asked questions
What size swimwear does a 3 month old baby wear?
A 3 month old usually wears size 3-6 months, for a height of 63–68 cm. If they're still under 63 cm, 1-3 months will fit, but not for long. You can enter their height on the product page and we'll suggest the size. More measurements in the size guide.
What does UPF 50+ mean on a newborn swim hat?
UPF 50+ is the fabric's ultraviolet protection factor: the higher it is, the less radiation gets through. At tuc tuc, it features on the sun hats in our newborn swim sets. Even so, baby should mostly be kept in the shade.
Can a newborn go to the beach in swimwear?
Yes, as long as you take sensible precautions: shade, avoiding the sunniest hours, a hat and plenty of fluids. Before bathing them or using sun cream, check with your paediatrician, who will advise what's suitable for baby's age.
What's included in a tuc tuc newborn swim set?
Depending on the style, it includes frilly swim bottoms or a T-shirt and bloomers set, plus a matching UPF 50+ protective sun hat. The designs feature heart, fruit or little bee prints with appliqué details.
Is swimwear a good gift for a baby born in spring?
Yes, it's a practical and original gift if you choose a size that will fit in summer: for a spring baby, 3-6 or 6-9 months. Add a poncho towel from our newborn towels for a complete gift.
How do you care for a newborn's swimwear and sun hat?
Rinse both in fresh water after each use. As a general rule, wash cold and inside out, without fabric softener or tumble drying, and dry in the shade. Follow each item's care label to keep the fabric and raised details looking their best.
