Size Guide
Finding the Perfect Fit
Every baby is unique, and their growth never follows one exact chart. To help you choose the most comfortable size, we recommend taking a quick moment to measure your little one before ordering. Using simple measurements like height, weight and chest or waist will make it easier to pick the size that feels just right. If your baby falls between two sizes, choosing the larger option usually gives a little extra room to grow and keeps them comfy for longer.
