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've found there's such a huge range in Prem sizing - simply making short clothing and labelling it "Prem" doesn't mean it will fit every early baby!

For premature babies using the baby's weight is the most accurate way to choose sizing. Some medical conditions such as IUGR can mean that a baby will be far smaller than others born at the same gestation. Every garment we sell has the weight range in the item's product description, as it can vary slightly between brands. To make it easy to chose the correct size for your baby our range is split into three main size groups, Micro Prem, Small Prem, and Prem.

Micro Prem: our littlest items up to approx 1.4kg (3lbs). This would be the equivalent of 0000000 (7 x 0) in size. Please be aware that there are not many babies that are able to wear clothes at this size, although we have had some 1.3kg babies that could be fully dressed!

Small Prem: 000000 (6 x 0) or a tiny prem size, ideal for baby's first clothing once they have graduated from an incubator. Small Prem clothing fits babies from between 1.3 and 1.8kg, to a maximum of weight of 2.4kg. Most of our stock is in this size as it is the most difficult to find. We do have a few items that fit 1.2-2kg, these are labelled as Extra Small Prem as they are in between the two sizes.

Prem: fits from 2.3kg up to either 3.2 or 3.6kg. 00000 (5 x 0) or a small newborn.

Anything that fits from 3.2kg upwards is classed as Newborn.

If you need to convert kilos and grams to pounds and ounces, we've got it covered with our weight conversion chart.

Our brands Itty Bitty Baby, Early Birds and Preemie-Yums both custom design especially for premature babies, resulting in properly sized clothes that fit baby snugly. Most of their items feature stretch knit cuffs around the wrists and ankles to help keep baby warm. Accurate sizing is an important issue so we are working hard to find suppliers that have this understanding and make correctly proportioned clothing!

Some Prem sized clothing available looks like chopped-off versions of the newborn items, short enough but very wide. Most early babies are fairly thin - wearing properly fitting clothes helps to keep them warm so baby can use his or her energy for growing instead.

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