Newborn Blue Shark Onesie with a friendly mouth across the tummy

The blue shark onesie for babies puts the joke where everyone can see it. Instead of teeth around the face, the wide pink mouth is printed across the tummy, so the shark smiles whenever your baby is held up. The body is a bright royal blue and the flannel stays soft on the inside.

On the hood, two round eyes sit above a line of white teeth, with small fins on either side that keep their shape. Nothing scratches, nothing hangs loose, and the hood can be pushed back in a warm room without taking the whole outfit off.

Naps and first photos suit the Infant Blue Shark Onesie

These baby blue shark pyjamas have to be quick to put on, and the zip runs from the neck to the ankle for exactly that reason. An infant shark onesie also needs room over a bodysuit, and the flannel holds warmth during a cold morning in the pushchair.

Blue is also the shade that photographs best against a pale blanket, which matters more than anyone admits before the first baby album. Keep it for a weekend by the sea, a first Halloween or a winter walk that deserves a picture.

A shark for every age

A parent can wear the matching adult blue shark onesie for a photo in the same ocean blue. The baby navy blue shark onesie offers a deeper tone for a sibling. Every shade swims together in the shark onesies collection.

Frequently Asked Questions

They’re made to keep you warm on the sofa through autumn and winter, so yes, they’re cosy. The relaxed fit lets air move around, though, so you won’t get that stuffy feeling you get from tight pyjamas.
Machine wash at 30°C on a gentle cycle. Turn them inside out and pop them in a mesh laundry bag to protect the hood. Skip the tumble dryer and the iron. They air-dry quickly and fluff right back up on their own.
Yes, every onesie we sell is unisex. The roomy cut works for men and women alike, our kids’ styles fit girls and boys just the same, and our baby sizes are cut the same way for everyone. Just check the size chart to find your fit.
