Please note our pyjamas are designed to be a snug fit (it is considered safest for children to wear snug fitting cotton pyjamas at night). We recommend buying the larger size by age (e.g. if your child is 4, buy the 4-5 rather than the 3-4). If you have any questions please do not hesitate to get in touch - firstname.lastname@example.org
Please note all sizes are in cm.
