What size do I get?

Please refer to our sizing guide and garment measurements below. Note that we only suggest height and weight measurements since all babies vary in size, however please refer to the length noted below when choosing a size. Generally speaking, our Swaddles are for babies 0-3 months, our Sacks from 3-10 months, and our early Walkers from 10 months+. Please lay flat to dry to keep your Slumber items at their current size and shape or allow up to an 8% differentiation in length after first dry cycle due to our products being untreated with any chemicals and solvents. The legs in our Walkers meet a snug fit guideline.
