Sizing

Baby Size Guide

All our sizes are based on age ranges. When in doubt, size up — babies grow quickly and a slightly larger fit is always more comfortable.

When to size up

If your baby is between sizes or on the heavier side for their age, always go up. Comfort matters more than a perfect fit.

Gifting tip

Buying as a gift? Choose one size up from the baby's current age — they'll grow into it and you'll get more use out of it.
