Sizing Guide

Buying for a Newborn?
We've simplified our sizing! Our Newborn and 0-3M sizes are now combined into a single Newborn size, eliminating any guesswork due to their minimal differences. Based on feedback, we've also adjusted the nappy area for an easier fit. We've tested this new sizing on little ones as early as 10 days old up to 8 weeks. With the ability to roll the sleeves and legs up or down, our combined sizing works perfectly.

Buying for a little one approaching 3 months? Based on our original sizing, if your little one is nearing 3 months old, we recommend upsizing to the 3-6M to get the most use out of your Ribbed Romper.
