Size Guide
Sleep Onesie
Please use your child's height to find the most appropriate and safe size for them. The Sleep Onesie should be fitted around the neck to avoid your child slipping through. 2.5 TOG and 3.5 TOG Sleep Onesies should not be used in a 5-point harness or car seat for safety reasons.
