SIZE GUIDE

for Premature Baby Clothing

Choosing the right size clothing can be difficult at the best of times - let alone for tiny babies where just a few centimetres makes a big difference. We quickly discovered that there's such a huge variation in premature sizing, surprisingly there's no official size standards for prem clothing!

When it comes to premature babies, the most accurate way to get the correct size is based on the baby's weight. Every garment we sell has the weight range in its product description, as it varies slightly between brands. You can also look out for our three main sizes, Micro Prem, Small Prem, and Prem.


Mini Micro Prem
We have a few bereavement gowns in this very tiny size, a beautiful option for dressing angel babies weighing under 1lb (450 grams).

Micro Prem
Our littlest clothing range, for babies up to approx 1.4kg (3lbs), and probably the equivalent of 0000000 (7 x 0). Please be aware that most babies this weight will be in an incubator and aren't able to wear clothes, although we have had some 1.3kg babies that could be fully dressed!

Extra Small Prem
There are a few items that fit approx 1.2-2kg, they are in between the Micro and Small Prem sizes.

Small Prem
000000 (6 x 0), a tiny prem size which is perfect for baby's first clothing once they graduate from the incubator. Small Prem should fit babies up to approx 2.4kg.

Prem
Fits from about 2.3kg up to either 3.2 or 3.6kg, depending on the individual clothing item. These are 00000 (5 x 0), usually the best fit for older prems or those smaller newborns.

Newborn
Anything that fits from babies from a minimum weight of 3.2kg and upwards.


We've searched for manufacturers that custom design especially for premature babies, resulting in beautiful clothes that are properly sized and fit your baby snugly. Natural fabrics like 100% Cotton or Merino are best for keeping baby warm, this combined with accurate sizing means your baby will stay warm and use that precious energy for growing!

Some brands of prem sized clothing looks like shortened versions of the newborn items, the length is ok but they can be a very wide fit. For these, baby will probably need a snug fitting layer underneath or extra blankets to help them stay warm, especially from Autumn and through Winter. I still find it incredible that staff in one baby shop told my mum to buy their range of teddy bear clothing for my 26 weeker - a teddy bear is easily 4 times fatter than a prem baby and it's never going to fit properly! Please also keep in mind that doll and teddy bear clothing isn't made to the same standard as baby clothes so it's really not a good option for dressing your premmie in.

Occasionally we receive items that seems to be larger or smaller than the labelled size, in which case we will put it into the appropriate size group. When this occurs we will make a note of the size difference in the products’ description. If you find an item fits for far more or less than the stated weight range then please let us know! We can pass on your feedback to our manufacturers and hopefully improve the fit for future little babies.
