Sizes start at 1-3 months. To keep him snug when he gets out of the water, have a look at our baby boy towels and baby boy swimwear.
Knit or woven: two kinds of swimwear
- Stretch knit: close-fitting, brief or trunk style. Great with a swim nappy because it doesn't sag.
- Woven: short swim shorts, light and quick-drying. More comfortable once he's walking and playing at the water's edge.
How to work out the size
Go by height: 69–71 cm is size 6-9 months, 72–74 cm is 9-12 months and 83–92 cm is 18-24 months. The swimwear should fit well at the waist and legs without leaving marks. Styles with an adjustable drawstring give you leeway if he's between sizes.
A great beach day with baby
Pick prints you love, but think about how they'll be used too: if you go to the pool every day, have a spare pair. Pair it with sun cream, a hat and shade when the sun is strongest, following your paediatrician's advice.
Briefs or shorts for crawling?
If he's still crawling or learning to sit up, knitted swim briefs move less and hold the nappy better. Save the woven swim shorts for when he's walking.
Frequently asked questions
What size swimwear should I buy for an 18 month old baby?
For an 18 month old, size 18-24 months usually works well, equivalent to 83–92 cm. If he's still under 83 cm, 12-18 months will be a closer fit. The most reliable way is to measure him standing up and enter his height on the product page. More detail in the size guide.
Which swimwear is most comfortable for a baby boy in a nappy?
Stretch-knit swim briefs are the most comfortable with a swim nappy, as they hold without gaping and don't slip down when he moves. Woven swim shorts also fit over a nappy, but they're looser and better once baby is walking.
What is the drawstring on baby boy swim shorts for?
The adjustable drawstring lets you tighten the waist so the shorts don't fall down when he gets out of the water and they're heavier when wet. Handy if baby is between two sizes. Always check the bow is tied securely and tucked inside if possible.
How do you dry baby boy swimwear quickly?
Gently squeeze it out without wringing and hang it in the shade somewhere airy. Woven quick-dry styles are ready in no time. As a general rule, wash cold and inside out, without tumble drying, and follow each item's care label.
What goes with baby boy swimwear for the beach?
Pair it with a hooded poncho towel to dry him off and keep him warm when he gets out of the water, and a light T-shirt for time in the shade. You'll find ponchos and towels in our baby boy towels, with prints that often match the swimwear.
What types of baby boy swimwear does tuc tuc sell?
tuc tuc sells baby boy swimwear in stretch knit brief styles and quick-dry woven fabric with a drawstring, in shark, dinosaur or surf prints with the odd raised detail. Sizes start at 1-3 months and every item complies with the EU REACH regulation.
