Newborn to 3 Months Clothing Sizing

Working out what size clothing to buy for a new baby can feel surprisingly tricky. Many families assume sizing is consistent, but in reality newborn-to-3-months clothing can vary between brands, which can make planning ahead a little stressful — especially when you’re already adjusting to life with a new baby.

In Australia, this stage is commonly labelled 0–3 months, 000 (triple-zero), or sometimes for accessories it might be labelled XS. As a general guide, these sizes are often designed for babies weighing around 4–6kg, but the actual fit can differ depending on the purpose, design, brand, fabric stretch, and style of the garment.

Because there isn’t a single universal sizing standard, one brand’s 000 may feel roomy and last for several weeks, while another may be a neater fit from the start. Choosing soft, breathable fabrics, easy-access designs for nappy changes, and comfortable layering pieces can help keep your baby settled, comfy and cosy.

At Kids of Eltham, we help families navigate these choices every day. Our experienced team can guide you through practical newborn clothing options that allow for comfort, growth, and seasonal needs, so you can shop with confidence rather than guesswork.

If you'd like personalised fitting advice, pop in and visit us in-store, or, give us a call (03) 9439 5700 if you need guidance before you shop online. We’re always here to support families with caring, practical advice during those precious early days.
