Clothing & Shoes Size Chart
Our sizing is based on the 75% percentile babies & chidlren, so will fit true to size for them. If child is bigger or smaller for their age you can size up or down accordingly!
All our Baby and Toddler Trousers, Dungarees, Babygrows and Playsuits are sized to fit cloth nappies. Cloth nappies are bigger than conventional ones, so we’ve left a bit more room in the body of the garment so your little one can wriggle around comfortably. These styles also fit well over disposable nappies.
