Onesies for Newborns & Babies First Moments
Our baby onesies and bodysuits are made for the earliest days, when comfort matters more than anything else. Every piece in this newborn range uses soft cotton fabric that sits gently against delicate skin.
We keep the collection gender-neutral, so it works whether you're shopping ahead of the birth or after you've met your baby. A good onesie stays a wardrobe staple because it's simple: one piece, easy to get on and off, and comfortable enough for a nap, tummy time, or a quiet afternoon at home.
Shop our baby onesies collection and build a newborn wardrobe that's soft, practical, and ready for everyday wear from day one. We're trusted by 45,000+ Mummas across Australia and beyond, and every piece gets the same care as our knitwear and keepsake ranges.
Why Choose Our Baby Onesies?
Newborn dressing should be quick and fuss-free. Here's what goes into every piece in this collection:
-
Soft cotton waffle fabric with a touch of stretch, gentle on delicate skin
-
A relaxed, breathable fit suited to everyday wear and layering under a jumper or cardigan
-
Practical construction with zipper or snap closures built around fast, easy nappy changes
-
Newborn and 0-3 month sizing, cut with extra room to grow
-
Same-day dispatch from our Sydney warehouse, plus free Australia-wide shipping on orders over $119
Every baby bodysuit in the range is designed in Australia, so the fit and finish are built around what works for a newborn's first weeks.
Onesies Chosen With Intention
Not every onesie is for the wash pile. Some are for the moment just before it: the first outfit, the trip home, the photo that gets sent to family before anyone else has met the baby.
Our My First Outfit sets pair a footed cotton onesie with a matching knotted beanie, in soft plain shades like Baby Blue and Powder White, plus a few gentle prints for parents who want a little more personality. The beanie frames the face without overpowering it, so the focus stays on your baby rather than the styling.
For gifting, the range extends into Birth Announcement Bundles and Gift Packs, each one pairing a onesie with a Cuddle Me Comforter in Elephant or Flamingo. It's a considered alternative to another set of everyday basics, especially for a baby shower or a newborn you haven't met yet.
Whether it's worn once for photos or a few times before it's put away, this tends to be the outfit that gets kept rather than handed down.

Baby Onesies FAQ
What's the difference between a baby onesie and a bodysuit?
Not much. In Australia, "onesie" and "bodysuit" are generally used for the same one-piece garment that fastens between the legs. Some parents use "onesie" for a fuller outfit with sleeves and feet, and "bodysuit" for a simpler singlet-style piece, but the terms overlap more than they differ, and you'll see both used across our range and elsewhere.
What size onesie does my newborn need?
Our onesies are cut with extra room to grow. Newborn (0000) suits babies up to around 4kg and 56cm, while 0-3 Months (000) suits 3 to 5kg and up to 62cm. If your baby sits between sizes, sizing up usually means more wear out of the piece.
Are your baby onesies suitable for sensitive skin?
Our onesies use a soft cotton waffle fabric with a touch of stretch, chosen to sit gently against newborn skin. For sensitive skin, check the fabric composition listed on each product page.
Should I choose snap or zip onesies?
As a general guide, snap and press stud closures are easy to adjust as your baby grows, while a two-way zip can speed up nappy changes in the newborn stage.
How do I wash and care for baby onesies?
We recommend a gentle cold machine wash, then laying flat or hanging in the shade to dry. Avoid high heat, which can affect both the softness of the cotton and the shape of the fit over time, and check care labels if you're combining loads with other fabrics.
Can baby onesies be worn as sleepwear?
Onesies can form part of a newborn's sleep outfit, but sleepwear choices should always follow current safe sleep guidelines for room temperature and layering. If you're unsure what's right for your baby's age and the season, your maternal health nurse or GP is the best source of guidance.
