Size guide

Our sizing

We want your little one to be comfy and carefree in whatever they wear so we hope this guide will help you find the perfect fit. 

Our sizing is based on 75% percentile babies and children, so will fit true to size for them. If your child is bigger or smaller for their age you can size up or down accordingly!

All our bottoms and all-in-ones are sized to fit cloth nappies which means there's a bit of extra room in the body of the garment so your little one can wriggle around comfortably. These styles also fit well over disposable nappies.

Don't forget...

We offer 6 month returns so can replace your style with another size if it’s not exactly what you’re looking for.
