Product description
The Grey Koala Critter Onesie turns a soft flannel romper into an animal: a character hood, a soft tummy panel and a zip down the front — sized for babies and toddlers from 56 to 110 cm.

The Grey Koala design
A baby koala, called a joey, lives in its mother's pouch for about six months. A sleepy grey koala for slow mornings and Australian-animal days.

The hood is the character
Each design is built into the hood — ears, horns, spines or fins stitched in place — so the animal reads from every angle, and the body stays a simple romper underneath.

Easy on, easy off
A zip runs down the front, which is what makes a costume usable on a wriggling baby: open it, change them, zip it back up.

Sent by the Aussie side
Her grandparents in Brisbane sent it, so she would have something from home. The video call was full of happy tears.

Frequently asked questions
Which size should I order?
Go by height. Size 70 fits 56–66 cm, 80 fits 66–70 cm, 90 fits 70–80 cm, 100 fits 80–90 cm, 110 fits 90–100 cm and 120 fits 100–110 cm. Between two sizes, take the larger — it leaves room for a layer underneath.
What is it made of?
100% polyester flannel, including the hood. Machine wash cold, inside out, and zip it up first.
Can my child sleep in it?
No. It is a costume and loungewear, not sleepwear. It is a loose, hooded plush garment; children should sleep in close-fitting sleepwear with nothing near the face. Take it off before naps and bedtime, and keep an eye on a baby in it so they do not overheat.
