Getting the size right for a new baby can feel confusing, especially when all the zeros start to blur together. The reassuring part is that if you go a little bigger, babies grow so quickly that they will soon fit into your gift.
In Australia, sizes 0000, 000, and 00 roughly follow the newborn months, and this guide is designed to help you choose something that will actually be worn for more than a few weeks!
If you are unsure, sizing up is usually the safer option, because looser pieces can be worn for longer, and some babies even start straight in 000 or 00.
And when you would rather not think about sizing at all, Pitter Patter Baby’s curated hampers take out the guesswork, with clothing and essentials chosen to feel thoughtful and practical.
We keep sizing simple by mostly featuring size 000 clothing in our hampers, because this 0–3 month size suits many newborns soon after birth without being outgrown in the first couple of weeks.
Australian Baby Sizes Explained: 00000 to Size 0
Australian baby clothing sizes are often labelled by a number of zeros, but sizing can vary between brands. Here’s a simple guide to help you choose.
AU Size |
Typical Guide |
Gift-Buyer Takeaway |
00000 |
Premature or very small baby |
Choose this only if you know the baby is premature or very small |
0000 |
Very Newborn |
Lovely for right-now photos, but often outgrown very quickly. |
000 |
0–3 months |
A safe choice when buying clothes and you’re not sure of the baby’s size. |
00 |
3–6 months |
A good option if you want your gift to last beyond the newborn stage. |
Why Sizes Vary Between Brands
Even when the label says the same size, fit can vary between brands, so it helps to treat the size as a guide rather than a guarantee. When you’re buying clothes as a gift, choosing flexible, easy-to-wear pieces reduces the risk of a poor fit. If you’re unsure, buy fewer items in each size because babies grow very fast.
If You’re Gifting Right After Birth
First visit or “welcome baby” moment.
Pick 0000 if the gift is meant for the immediate newborn stage and you know that the bub is very tiny. If you’re considering delivery to a hospital, we strongly recommend a home address where possible due to fast discharge times
If You’re Gifting for the Next Few Months
The safest default.
Choose 000 when you want your gift to be worn soon, but not necessarily in week one. For many gift buyers, this is the best compromise.
If You Want the Gift to Last Longer
Or you think the baby will grow fast.
Choose 00 if you want the family to have something ready for the next stage. This works well because families often receive lots of tiny outfits early on but fewer everyday pieces are sized to be used closer to the end of the baby's first year.

Newborn Baby Gifts in Australia: Checklist
- If you don’t know the baby’s size, choose 000 or 00, or skip clothing altogether and gift wraps, blankets, or books.
- Think about the season where the family lives. Cooler nights and humid days change what’s practical.
- Avoid loading up on tiny outfits. Balance cute pieces with items that last beyond the first few weeks.
- Double-check delivery details, especially unit numbers, business names, or hospital ward and room information.
- If you’re gifting a nappy cake, allow extra time for delivery compared to gift hampers.
