The smallest newborn babies clothes in Australia are generally size 0000, which is for newborns weighing up to 4kg and measuring up to 56cm in height.
Size 0000 | Newborn
This size 0000 is a safe bet unless the baby is particularly smaller or bigger than average. It's great for newborns from roughly 0 to 4-6 weeks old with an approximate height of up to 56 cm and a weight of up to 4 kg. For a "home outfit" this is the best size to choose.
Most newborns will be in size 0000 (newborn size) for 2-6 weeks and then move to size 000 | 0-3 months. From size 000 | 0-3 months, it is best to check approx weight and length of garment on the size chart. Remember, every baby grows differently and similar to adult clothes, the sizes vary from brand to brand.
Size 00 can be anywhere from 0.5 to 2 inches (1 to 5 cm) smaller than size 0. Size zero often refers to thin individuals (especially women and adolescent girls), or trends associated with them.
Newborn baby clothes sizes
Whereas size 0-3 months should fit your baby up to 12 pounds, and you can always roll up sleeves and pant legs for a few weeks while baby grows into the larger size. If your baby is predicted to be petite, or you have a preemie, Newborn or Preemie sizes make a little more sense.
1. Size 00000. The smallest on the market, size 00000 is designed to fit babies who are born prematurely or are particularly small. As a general rule, they weigh less than 2kg and are under 55cm in length.
Size 000 is intended to fit babies from 0-3 months, and size 00 is for babies from 3-6 months. Some bigger newborns might be ready to go straight into a size 00. You might have to roll up the sleeves, but it won't be for long.
You should dress your baby one-to-two layers to sleep—make sure they don't have any strings or ties—and never cover baby's head. Until the baby can roll on their own, a swaddle or sleep sack can be one of those layers.
The longest a baby usually wears newborn is about 1-2 weeks after their due date (even if born early- by the due date they are usually in newborn size). Therefore, for a new baby gift, I would go with a 3M (0-3M) or 6M (3-6M) size to get a little longer wear.
A “000” (triple zero) capsule is the largest size available. In cases where capsule sizes are indicated with "0" names, 000s are the largest, while 0s are smaller.

A size zero figure typically refers to the body size of a woman. A bust size of 31 inches, waist size of 23 inches and hip size of 32 inches is generally considered as a size zero figure.
If you're buying for your unborn baby, in general it's best to buy 0-3 month clothes, as newborn size can be outgrown very quickly. It's important to never dress them in clothes that are much too big though, especially sleepwear. It could be a suffocation risk.
Full-term babies born with the average birth weight will typically wear newborn size clothes for anywhere from two to six weeks, but some might need to move up sooner while some might skip the newborn-size clothing altogether.
It's recommended that you wash the clothes no earlier than 4-6 weeks before the baby's arrival. Anything between that and the baby's birth is also fine.
0 – 3 month – Plan on two outfits and a sleeper each day, but don't overbuy in this range as your child will grow quickly. 3 – 6 month – Plan on one to two outfits a day plus a sleeper.
3-month-old baby weight and length
The average weight of a 3-month-old baby is 12.9 pounds for girls and 14.1 pounds for boys; average length is 23.5 inches for girls and 24.2 inches for boys.
'Size zero' was first used in 1966 for British supermodel Twiggy, who had a fragile figure. Now, 'size zero' is a women's clothing size in the US system, equivalent to a UK size 4, with a waist measurement of 23 inches, the average girth of an 8-year-old girl.
So a 24 is equivalent to a size 0.
