Baby on the way but you already have a wardrobe full of miniature outfits eagerly awaiting their debut? We don’t blame you. Baby clothes are super cute. They’re tiny. They’re adorable. They’re very easy to buy just one more outfit.

A newborn outfit that is a must is a onesie (also known as a baby growsuit). Newborn onesies are a full body suit designed to make dressing your baby easy while keeping them snug as a bug. You can layer them up underneath with a singlet for extra warmth and can be worn day or night. Some newborn onesies come with press studs while others come with zippers, two way zippers or Velcro.

Onesies are also really practical because you don’t need to worry about your baby’s top riding up or pants falling down like you do when they wriggle around in two-piece outfits, this also means it helps secure their nappy in place.

Another thing to note when shopping for a onesie is to think about the quality of materials. We recommend super soft cotton (and if it’s organic, even better) that promotes breathability and is really gentle on your bub’s skin.

The position of the zip or the press studs is important too, as you want something that makes dressing your baby easy. Growsuits with a diagonal zipper or across the torso create a wider opening to put bub inside. Two way zippers allow you to take bubs legs out and do a nappy change without needing to undress their top half (great for winter!).

If you’re currently shopping for onesies for your bub, we’ve got you sorted with our Best Onesies in Australia in 2023 List. We compiled this list after surveying Australian parents in the TBE community about the onesies they used and loved with the newborn. Here are the results:
