Questions parents ask
Size by weight + height, not by age. Babies grow in irregular jumps; the labels lie. If you're between two sizes, size up — bamboo stretches a little but shouldn't feel tight. Our chart matches Carter's, Kyte, and Kickee, so if a recent zippered footie fit, the same size here will too. Full size guide at /size-guide.
