Baby & Child Size Guide

If your baby is born full term and is an average size [ 2.7-4kg / 6-9lbs ], we advise you to select our 'Newborn' size or if you would like a little growing room, our 0-3 months size. First size is for smaller than average babies. Don’t forget your new baby grows very quickly in the first few weeks.

Many customers like to order a garment closer to the baby’s age for snugger fitting garments like sleepsuits and vests but a bigger size for roomier garments like snowsuits where clothing is worn underneath.

Our children’s range is designed for the height and weight of your child and the age group is approximate.

Our garments are true to size and British standard measurements.

In order to work out the correct size for your child measure directly on your baby/child's body.

Measure the whole length from head to foot of the child to get the correct size in cm/inches.

All our products can be washed with care at 30° and tumble dried with care on a low heat setting.

Please follow care instructions printed on inside care labels.
